DIY: Rear Brakes on an Audi S4

1. Park the S4 on a level, flat surface. Use a tire iron to loosen the lug nuts that hold the rear wheels on. Lift the back of the car with a jack and lower it onto jack stands placed under the car at the proper places.
2. Finish removing the lug nuts and the wheels. Set the wheels out of the way. Remove the brake caliper spring clip on the outside of the caliper with a pair of pliers. Loosen and remove the caliper bolts located at the top and bottom of the brake caliper facing the wheel well.
3. Slide the caliper off the brake rotor. Support the brake rotor by tying it to a nearby suspension piece, so there is no weight on the soft brake line.
4. Remove the brake pads from the caliper and the caliper carrier. Disconnect the line for the brake wear sensor. Remove the bolts that hold the brake caliper carrier to the car. Set the carrier aside. Remove the brake rotor set screw, located in the face of the rotor. Pull the rotor straight off the hub.
5. Clean the area where the rotor mounts to the hub. Slide the new rotor onto the hub. Now is a good time to upgrade to cross-drilled rotors, which provide superior cooling. Install the rotor set screw. Bolt the caliper carrier back on.
6. Open the lid to the brake fluid reservoir located in the engine bay. Using a syringe, remove about ½-inch of the brake fluid. Place the Audi brake caliper tool over the piston in the caliper. The tool has metal dowels that fit into holes on the piston. Turn the tool so that it retracts and turns the piston into the caliper to make room for the new, thicker brake pads.
7. Install the new brake pads. Slide the caliper back over the new rotor. Install and tighten the caliper bolts. Connect the brake wear sensor, ensuring it is routed correctly. Reinstall the brake caliper clips. Repeat for the other side. Place the wheels back on the car and lower it. Fill the brake fluid reservoir with fresh brake fluid. Pump the brakes until the brake pedal feels firm again.

12. Reattach the weather stripping and reconnect the door panel. Raise and lower the window to confirm a successful window regulator replacement.

How to Troubleshoot a 2003 Audi Allroad Quattro

1. Make sure your Quattro is able to start and run normally. A redesign in 2003 changed the fuel-pump components. Unfortunately, this change was for the worse. The fuel pump may fail prematurely. This problem is covered under a factory recall, and the dealership will replace this item at no charge to you.
2. Check for low oil pressure. Some Quattros in 2003 may experience low oil pressure. Unfortunately, this is due to the turbocharger setup from the factory. The turbocharger gets warm and may cause oil in the engine to coagulate and form sludge in critical areas. This may interfere with the oil pickup in the crankcase, which, in turn, can affect lubrication of critical engine components. There is no known recall for this issue; however, if the Quattro is experiencing low oil pressure, have the turbocharger system checked and serviced immediately by an Audi dealership.
3. Check for oil leaks on the seals and gaskets of the camshaft adjusters if you have a 3.0-liter engine on your Audi. Some Quattros were fitted with an optional 3.0-liter engine. The seals and gaskets on the camshaft adjusters may prematurely fail. Although this is not covered by a factory recall, have this problem serviced immediately by an Audi dealership.

How to Add R134 to a BMW

1. Secure the low-side service hose onto your container of R134a. Keep the valve closed on the service hose.
2. Locate the low-side quick disconnect valve on the accumulator hose. Again, the valve measures 13mm and connects to the silver hose extending from the accumulator. On most BMWs, the accumulator is on the passenger side and it is a silver tube with two hoses coming out of it. One side is the low-side hose and the second is the high-side hose. The valve is on the low-side hose.
3. Remove the cap from the hose and press the other end of the service hose onto the low-size valve. It is a quick disconnect valve so the hose will snap on just by pressing it onto the valve.
4. Turn on your BMW and turn on the air conditioner. Open the valve on the service hose and charge the air conditioner until the pressure gauge on the service hose reaches between 35psi and 40psi.
5. Turn off your BMW and disconnect the service hose from the low-side valve. Place the cap on the valve to complete the job.

How to Change the Transmission Fluid in an Automatic Audi TT 2003

1. Park the Audi TT on a flat surface and raise the front of the car up on a pair of jack stands. Wait 30 minutes before performing any work below the engine so the car has time to cool off.
2. Slide underneath the car and locate the gearbox in the center of the engine. This is a silver, round metal tank with a pipe coming out the front and the back. Place a drain pan beneath the gearbox.
3. Remove the drain bolt on the front pipe coming from the gearbox with the Audi socket wrench. Wait 10 to 15 minutes until the fluid stops draining from the the gearbox. Replace the drain bolt.
4. Remove the fill plug on the back pipe with the specialized Audi socket wrench. Place the plastic tube of the fluid pump into the fill plug and pump the handle to inject the fluid into the gearbox. Fill it with fluid until it begins to drip slowly from the fill plug. Replace the fill plug. Lower the car from the jack stands.

How to Change the Brakes on a 2003 Mercedes C320

1. Loosen the lug nuts with the tire iron or 17 mm socket and ratchet. Lift the Mercedes' tires off the ground with the jack and place jack stands under the wheel axles. Lower the vehicle onto the stands and remove the lug nuts. Take the wheels off.
2. Place a screwdriver into the upper brake pad pins slot and tap the back of the screwdriver to force the pin through the back side of the caliper. Repeat the process for the lower pin.
3. Squeeze the brake pads against the side of the caliper with a pair of channel lock pliers to force the caliper pistons into the sides of the caliper. The pistons press the pads against the rotors during braking. Open the pistons to aid in removing the worn brake pads and rotor, and to make room for the thicker new brake pads.
4. Slide both brake pads from each brake assembly and discard them. Remove the two caliper bolts on the back side of the caliper with a 14 mm socket and ratchet. Lift the caliper from the rotor and rest it on the steering arm above the wheel hub. Do not allow the caliper to hang by the brake line.
5. Remove the rotor retaining screw with a No. 3 Phillips-head screwdriver. Pull the rotor from the wheel hub. Spray chain lubricant behind the rotor or tap the disc's outer surface with a hammer to remove a stuck rotor.
6. Clean the new rotor and wheel hub with brake parts cleaner and a cloth towel. Place the new rotor onto the wheel hub and align the hole of the disc with the one on the hub for the retaining screw. Replace the screw with the screwdriver.
7. Apply brake grease to the back side of the new brake pads and caliper slide pins. Place the new pads onto the inner sides of the caliper. Place the caliper back over the rotor and screw in the caliper bolts with the 14 mm socket and ratchet.
8. Slide the brake pad pins back into place from the back side of the caliper. Replace the wheel onto the Mercedes' wheel bolts.
9. Repeat steps 2 through 8 for each additional brake that requires changing.
10. Lift the vehicle with the jack and remove the jack stands. Lower the tires to the ground and tighten the lug nuts with the tire iron. Move to the driver's seat.
11. Start the engine. Press the brake pedal slowly to the floor. Release the pedal and depress it two more times until the brake pedal response returns to normal. Pull the hood release lever located under the dashboard on the driver's side and move to the front of the vehicle.
12. Lift the hood. Remove the master cylinder cap located on the right side of the C320's engine. Place a funnel into the container. Fill the reservoir with brake fluid as needed. Remove the funnel and replace the master cylinder cap. Close the hood.

How to Oil Service a BMW R850R

1. Place your R850R on the center stand and turn on the engine. Let the engine idle for five to 10 minutes. This allows the oil to warm up and flow out of the engine more quickly.
2. Shut off the engine. Position the oil drain pan underneath the motorcycle's engine. Remove the oil drain plug from the oil pan with an 8 mm Allen wrench.
3. Drain the oil out of the engine and into the pan.
4. Remove the oil filter next to the oil pan, using the oil filter wrench. Drop the old filter into the drain pan. Attach the new filter.
5. Reinstall the oil drain plug and tighten it using the 8 mm Allen wrench.
6. Open the oil filler cap located at the top of the R850R. Slowly pour in 3.75 quarts of fresh oil. Reattach the oil filler cap.
7. Remove the BMW R850R from the center stand and turn on the engine again. Allow it to idle for a few minutes so that the new oil will circulate throughout the engine.
8. Turn off the engine and allow your BMW motorcycle to sit for several hours. Check the oil indicator sight glass near the engine oil pan to ensure that the oil level is at the minimum level. Add more oil as needed.

How to Troubleshoot a 1992 325I BMW Transmission

1. Start the engine and let it run for about 15 minutes.
2. Open the hood and pull the looped handle in the back of the engine all the way out. This is the transmission dipstick.
3. Examine the fluid. It should be red in color. If it is reddish-brown, or smells burnt, then you will need to have the transmission fluid changed and your transmission checked for any internal damage.
4. Check the fluid level. Examine the end of the dipstick. The fluid level should be between the upper and lower marks on the end of the dipstick. If it isn't, you'll need to add more transmission fluid until the fluid levels are adequate.
5. Put the car into gear. If it grinds or is hard going into gear, you will need to have the transmission serviced. Grinding gears can indicate chipped teeth on the gears. However, it is more likely that the synchronizers are damaged.

How to Upgrade My Volkswagen Passat

1. Lower the suspension and install performance shocks. Like most vehicles, when the Passat leaves the factory, it has an undesirable ride height. Install lowering springs from Eibach matched with a set of performance shocks. Your Passat will look far better and will also handle better. Eibach also offers a front anti-roll bar for the B5-generation Passat.
2. Replace the stock wheels. Once you have lowered the suspension, the next logical step is to install a larger diameter set of wheels and tires. Most specialty tire retailers will have a large selection of wheel and tires packages for the Passat. For a German make, like the Passat, a set of BBS wheels look great. Lighter wheels will reduce the unsprung weight of your VW's suspension, and wider, softer compound tires will give it more grip in the corners.
3. Tune the motor for more power. The Passat's 1.8T turbocharged engine, in particular, takes well to modifications. Euro Sport Tuning offers a full array of engine upgrades, including reprogrammed ECUs (Engine Control Units) that add more horsepower and increase the engine's redline, intercoolers for turbocharged engines and free flow exhaust systems. (See Resources 1)
4. Upgrade the braking. More power means that your Passat can also use some extra braking. Start by installing a set of cross-drilled rotors, which help dissipate heat and reduce brake fade during aggressive and repeated braking. Continue the improvements in this area by installing brake pads made from performance-oriented pad material and braided steel brake lines for a firmer brake pedal feel.
5. Replace the original seats with aftermarket bucket seats from Recaro. With your Passat accelerating, braking and cornering much quicker now, deeper bucket seats will only add to the experience, ensuring that driver and passenger stay firmly in place during sporty driving.
6. Upgrade the exterior with better lighting and ground effect. There are not a huge number of choices when it comes to upgrading the exterior of your Passat, so you can keep it simple by installing PIAA headlight and fog light bulbs and a pair of headlight eyebrows. (See Resources 1) Andy's Auto Sport offers a few body kits for the Passat if you want to make the exterior look even more unusual. (See Resources 3) However, the Passat is a handsome, well-styled car in original form and looks best with a minimum of external aesthetic changes.

How to Replace the Belts on a BMW 325i

1. Disconnect the negative cable from the battery. The negative cable is black.
2. Remove the bolts holding the black plastic splash shield underneath the car. Remove the shield. Open the lid for the coolant tank. Drain coolant from the block into a container by removing the drain bolt under the exhaust manifold. The exhaust manifold is located on the passenger side, behind the oil filter.
3. Grab a 32-mm side open-end wrench. Use this to remove the cooling fan from the water pump by turning the nut clockwise to remove it. Once removed, keep it stored in an upright position and remove the fan shroud by unclipping the two clips that hold it on. Remove the coolant hoses from the radiator and water pump. Remember which hose goes where for when you put them back on.
4. Remove the two mounting bolts that are holding the radiator in place. Remove the radiator. Remove the three bolts that are holding the distributor cap in place and then remove the cap. Loosen the three screws that are holding the rotos in place and remove the rotor. There will also be a dust shield underneath the rotor that you need to remove as well.
5. Find the four 10mm bolts that are holding the water pump in place and loosen them. Find the six 13mm bolts holding the crank pulley in place and loosen those as well. Loosen and remove the belts for power steering, air conditioner and alternator and water pump.
6. Remove the water pump bolts and the pump itself. Finish removing the crank pulley bolts and the crank pulley itself. There is something called a harmonic damper located behind the pulley that you need to leave in place.
7. Remove the three bolts holding the upper camshaft cover in place. Use a 22mm socket and ratchet on the crankshaft nut and turn clockwise until the mark on the sprocket lines up with the notch on the head. The mark sometimes looks like an arrow or an indent. Also, make sure that the 'O/T' mark on the harmonic damper lines up with the notch on the lower timing belt cover. If these timing marks are not aligned, the process will not work successfully.
8. Continue to remove the crankshaft damper. Remove the bolts holding the lower camshaft cover into place and loosen the top bolt for the timing belt tensioner pulley. Loosen the lower bolt as well and rotate the tensioner towards passenger side of the car. Then, tighten the upper bolt back.
9. Slide the timing belt off of its pulleys and turn the sprockets clockwise, starting at the camshaft sprocket. Remove the top tensioner bolt, guide pin and spring. Remove the lower bolt as well and the tensioner. Install the new timing belt tensioner pulley. Hand tighten the lower bolt and install the guide pin and spring. Rotate the pulley towards the passenger side and loosely put in the bolt. Push the pulley all the way towards the passenger side and tighten the bolt.
10. Adjust the timing marks if you need to to make them line up. Install the new timing belt. Work in a clockwise direction and make sure to keep it tight between each sprocket. Loosen the upper tensioner bolt until the tensioner rotates to the driver's side. This will engage the timing belt.
11. Install the lower timing cover and harmonic damper. Make sure that the timing belt marks line up by rotating the crankshaft with the socket two full turns. If they do not align, you need to remove the belt and install it again until the lines match up.
12. Tighten the upper and lower tensioner pulleys and bolts. Reinstall camshaft cover, water pump, belts, radiator and fan belt. Reinstall the distributor cap and rotor and radiator hoses. Plug the drain in the block and top engine off with coolant. Reinstall splash shield.

How to Remove a Mercedes Cylinder Head

1. Lift the hood and study the layout of the cylinder head which needs to be removed. The fuel sending unit will need to be removed or disabled before you attempt to remove the cylinder head, as well as the cylinder head cover and valve covers. Refer to the specific engine layout in your Mercedes Benz repair guide to determine what must be removed prior to removing the cylinder head.
2. Unbolt the cylinder head by loosening the retaining bolts one at a time starting with the bottom bolt in the center. The next bolt will be the top center. Remove the next bolt in a clockwise fashion from the bottom, then remove the bolt to the right of the one at the top. Continue in this fashion until all the head bolts are removed completely. Do not attempt to pry or pull on the cylinder head until the bolts are removed.
3. Pull the cylinder head away from the engine block, being careful to avoid bending the valves or allowing waste gasket material or other debris to enter the cylinders. If replacing the head gasket, scrape the old gasket material away with a plastic scraper if necessary, and ensure that the mounting surface of the cylinder head is completely clean before reinstalling the head.

How to Check the Power Steering Fluid on a 2002 BMW 325

1. Open the car’s hood. The power-steering reservoir on a 2002 325i is located next to the coolant reservoir in the engine bay above the power-steering pump.
2. Clean the power-steering fluid reservoir and the area around it with a clean rag to avoid any dirt and debris getting in the fluid. Turn the lid of the reservoir by hand counterclockwise to loosen and remove it.
3. Look at the bottom of the lid, which will have a plastic dipstick on it. Wipe the dipstick with a rag so that it is clean and then dip it back in the reservoir. Pull it back out and look at the dipstick.
4. Pour the appropriate amount of fluid into the reservoir until the dipstick shows that it is to the full mark. Replace the lid for the reservoir. If the fluid level was very low, turn the steering wheel back and forth through the full range to make sure the steering is not heavy and does make any strange noises.

How to Turn On a Mercedes Benz C280 Fog Lamp

1. Turn your C280's engine on, or insert the key and turn it to "Acc."

How to Install the Front Brake Rotors on a 96 BMW 740IL

1. Loosen the BMW’s front wheel bolts with a ratchet and socket. Raise the front of the vehicle with a floor jack and place jack stands under its frame rails. Lower the 740iL onto the jack stands. Remove the wheel bolts and remove the front wheels.
2. Trace the brake pad level sensor wire -- on the driver’s side only -- until you find where it connects to the BMW’s wiring harness. Press and hold the unlocking button on the wiring harness, then unplug it from the vehicle’s harness. Unfasten the retaining bolt that secures the pad level sensor bracket to the caliper, using a ratchet and socket, and pull the level sensor wire from its routing clip.
3. Instruct an assistant to press and hold the brake pedal. Remove the rotor-retaining screw in the center of the rotor with a ratchet and a hex-bit socket.
4. Find the out caliper-retaining clip -- the metal clip on the outer part of the caliper. Remove this clip by prying it out with a flat-head screwdriver.
5. Pull the plastic caps covering the caliper bolts from the caliper. Remove the two caliper pins with a ratchet and hex-bit socket, then pull the caliper up and out of the caliper bracket. Hang the caliper from a nearby suspension component with a bungee cord. If the outer brake pad did not fall out when you removed the caliper, pull the pad from the caliper.
6. Remove the two caliper bracket bolts with a ratchet and socket. Pull the caliper bracket off the steering knuckle.
7. Pull the rotor of the 740iL’s hub. If the rotor does not pull off easily, lightly tap it with a rubber mallet to free it. Set a new rotor on the front hub, lining up its screw hole with that in the hub. Hand-tighten the rotor-retaining screw. Hold the rotor firmly to prevent it from turning, then tighten the rotor-retaining screw to 12 foot-pounds with a torque wrench and socket.
8. Set the caliper bracket back on the front steering knuckle and hand-thread its retaining bolts. Torque the caliper bracket bolts to 81 foot-pounds with a torque wrench and socket.
9. Position a drain pan under the caliper. Place an 8-inch C-clamp over the caliper so that its fixed part touches the rear of the caliper body and its screw part contacts the inner brake pad. Tighten the C-clamp until it touches the inner brake pad, then set a combination wrench on the bleeder valve -- the ¼-inch metal valve -- on top of the caliper.
10. Turn the bleeder valve a half-turn counterclockwise to open it, then immediately start tightening the C-clamp to press the caliper piston into the caliper. Continue tightening the C-clamp until the piston stops moving, then immediately close the bleeder valve.
11. Pull the old inner brake pad from the caliper; notice that small metal clips hold it inside the cavity in the piston. The brake pad level sensor comes off with the inner brake pad. Line up the clips on the rear of the new inner brake pad with the cavity in the piston, then press the brake pad toward the piston until the pad is flat against the end of the piston. On the driver’s side only, press a new pad level sensor into the groove on the top of the brake pad, nearest to the hole in the top of the caliper.
12. Set the outer brake pad in the caliper and immediately set the caliper on its bracket. Wipe all of the old grease off the caliper pins and apply a thin coat of new disc brake grease onto the smooth part of each pin. Hand-thread the caliper pins into the caliper, then torque them to 22 foot-pounds with a torque wrench and hex-bit socket.
13. Set the outer caliper-retaining clip so that the ends of its longest side are between the caliper bracket and the center hub of the rotor. Press the clip upward to insert its two tabs into the two holes in the outer part of the caliper.
14. Route the pad level sensor wiring in the same manner the old one was positioned. Hand-tighten the pad level sensor bracket bolt, then tighten it with a ratchet and socket. Press the pad level sensor wiring into the routing clip, then plug it into the BMW’s wiring harness.
15. Press the plastic caps back in place over the caliper guide pins.
16. Repeat Steps 2 through 15 to replace the rotor on the other side of the 740iL.
17. Reinstall the front wheels on the 740iL’s front hubs, then hand-tighten the wheel bolts. Raise the BMW off the jack stands with a floor jack and remove the jack stands. Lower the vehicle to the ground. Tighten the wheel bolts, in a crisscross pattern, to between 95 and 111 foot-pounds with a torque wrench and socket.
18. Press and release the brake pedal until it feels firm. Check the brake fluid level in the reservoir. Add DOT 4 brake fluid, as needed, to bring the level up to the “Max" line on the reservoir.
19. Turn the ignition to the “1” position and leave it in that position for at least 30 seconds to reset the brake pad level light. Turn the ignition off.

How to Customize a Mercedes

1. Install a set of aftermarket wheels. A Mercedes looks great with a larger set of wheels and tires, so start the modifying process by swapping out the stock wheels for lighter, more aggressive alloys. Many companies make wheels for Mercedes, but it's best to stick with established brands like BBS, AMG and AC Schnitzer. Try to steer clear of 20-inch chrome rims if possible.
2. Install a lower, stiffer suspension for a better appearance and additional performance. Pair a set of high-quality lowering springs from a company like Brabus or Carlsson with some stiffer shocks from Bilstein or Koni. If you really want to increase the car's handling, bolt on a set of larger sway bars, which will really reduce body roll during fast cornering. Your car will look better and perform better, with more nimble, sure-footed cornering.
3. Increase the engine's horsepower. Replace the stock and restrictive exhaust for a larger-diameter setup and feel the benefit of more power and a more tuned exhaust note. You can go a step further by reprogramming the ECU (electronic control unit) and installing a better air intake. Beyond that, the sky is the limit with supercharger and turbocharger kits that will add a tremendous amount of power to your car.
4. Upgrade your car's stopping power. Better brakes make sure the performance of your Mercedes remains balanced, particularly if you are planning on upgrading the horsepower. Brembo offers big brake kit upgrades for a dramatic improvement in stopping power. If you want to keep it basic, then performance-oriented pads and cross-drilled rotors from a company like Zimmerman is a good bet.
5. Modify the interior. In stock form, a Mercedes interior is a pretty great place to spend time, but there are several options for upgrading this aspect of the car. Start with an aluminum shift knob and go from there. There are aluminum and carbon fiber trim kits available for most cars. You can even install a rich Alcantara (faux suede) headliner for a very upscale look and feel.
6. Unless your Mercedes is one of the high-performance AMG variants, which come standard with an array of performance and aesthetic enhancements, the exterior is probably on the subtle side. Several companies offer aesthetic enhancements, with OEM (Original Equipment Manufacturer) AMG parts and products from companies like Brabus and MKB being some of the very best in quality and fitment. Have these parts installed and painted by a company that specializes in German marques in order to get the best results.

How to Discolor Used Engine Oil

1. Drain old, used oil from the car and contain it in a sealed bucket or jug. Used motor oil is a pollutant that can harm the environment, so it needs to be stored in a container it will not leak from.
2. Pour a gallon of your fluid into the old oil, using a funnel to avoid spilling it. Water, antifreeze and similar water-based fluids will all change the color of the oil. Water is the best choice because it is not a pollutant or toxic to the environment and engine oil will mix with water, though it may separate if left to sit for long periods.
3. Stir or shake the oil and water mixture. The oil should take on a lighter, milky color and may bear a resemblance to a chocolate milkshake in terms of color and consistency. If the oil is still too dark, continue adding water.

How to Manuel Shift for the Best Gas Mileage

1. Listen to your car as you drive. You can hear the engine revving louder as the RPM increase. Your goal is to keep the RPM low without stalling the car. This will decrease the amount of power you have and slow down your acceleration time, because the engine will not be working as hard. It will take some practice to listen to your car and monitor the RPM gauge before you can shift to optimize your gas mileage.You do not need to have a manual transmission to do this. If your automatic transmission has the option to switch into a tiptronic mode where you can control the gears, you can shift gears in your automatic vehicle to get better gas mileage.
2. Shift up to a higher gear between 2 and 3 RPM until you get to your optimal gear for the speed you want to reach. If you quickly need power, for example when climbing a hill, you can downshift to a lower gear to increase your RPM and gain enough power to drive up the hill.
3. Shift down to a lower gear later than normally. As you decelerate, wait until the RPM get low before downshifting. This will prevent the engine from revving high when you shift to a lower gear. If you need to slow down to stop, you can take the car out of gear to glide to a stop.

How to Power Shift a BMW 323

1. Turn on your car and engage first gear.
2. Engage full-throttle and accelerate forward.

4. Repeat Step 3 for each gear change. Do not attempt to repeat the procedure upon downshift.

How to Tell If the Idle Control Valve Is Bad?

1. Start your car, and listen to the idle. Does it sound faster or slower than usual? Does it 'stumble?' All of these things are symptoms of a failing control valve.
2. Locate the idle control valve on the intake. In every car they look different so refer to the repair manual of your specific car to know what it looks like.
3. Remove valve from the intake and clean with carburator cleaner. It will probably be covered with black varnish so some amount of cleaning will be necessary. Once clean, reinstall.
4. Start the car and determine if the engine's idling has improved. If the idling has not improved, you may need to replace the ICV.

How to Diagnose a Car That#039;s Running Hot

1. Check the antifreeze/coolant level in your radiator. Wait until the car has cooled down and the engine is cold, and then remove the radiator cap. If the fluid level is sufficient, you should be able to visually see the liquid inside. If it is low, add more according to your car's specifications. If you have to add more than a pint of fluid, it is possible that you have a leak.
2. Check your oil level. Remove the dipstick from under your hood and wipe it clean with a rag. Reinsert the stick, pull it out and then read the level based on the markings on the stick. Oil serves as a lubricant and if there is not an adequate amount, then your car will be working harder to perform and this can cause overheating.
3. Investigate the thermostat. This should be done with the car powered off, and while the engine is slightly warm. This problem is one that will most often need to handled by a mechanic. For a do-it-yourself check, however, hold your hand to both the lower and upper radiator hoses; both should feel warm to the touch. If you have just one that is warm while the other is cold, the thermostat could be the culprit causing the overheating.
4. Visit your mechanic. Unless you are trained to handle these problems, it is best to leave them to a professional. A mechanic can hook your car up to a diagnostic computer that will give a reading and a specific report on the problem(s) with your vehicle.
