How to Replace an Alternator in an S420 Mercedes

1. Disconnect the cable running to the negative battery terminal. Loosen the nut on the cable clamp running to the negative battery terminal with a socket wrench and slide the clamp off the terminal.
2. Open the hood and look straight at the front of the engine. You will see a belt that 'snakes' through a system of pulleys. This is the the serpentine belt, also called a 'drive belt.' It needs to be removed in order to remove the alternator. Draw a diagram of the belt path and orientation. You will need this diagram when reinstalling the belt.
3. Remove tension on the drive belt with a socket wrench and a 14mm socket. The tensioner is on the driver's side of the engine, near the front of the engine. The tensioner bolt protrudes out of the engine's pulley system at a 45 degree angle, with a little bit of a hex shape at the top of the bolt and a small hole in the middle of the bolt. Turn the bolt counterclockwise to remove tension on the belt.
4. Pull the belt off the pulley system.
5. Remove the electrical connector running to the alternator.
6. Remove the alternator. Remove the upper and lower alternator mounting bolts. The alternator is mounted on the front of the engine.
7. Install the new alternator. Installation is the reverse of removal. Make sure that you orient the drive belt properly when installing it.
8. Attempt to start the engine. As long as the battery was not drained entirely when the alternator failed, you should be able to start the engine. If the battery is dead, you may need to install a new battery. To do this, remove the cable clamps on the battery terminals following the procedure in Step 1. This time, you'll be removing both the positive and negative cables. Always remove the negative cable first and attach it last. Once the cable clamps have been removed from the terminal, remove the battery from the battery holder and drop in a new battery. Then, reconnect the battery terminals and tighten the cable clamps.
9. Check to make sure that the battery light does not stay on once the Mercedes is running.

How to Use Regular Gasoline in a Mercedes

1. Park your car so that the gas tank is adjacent to the pump.
2. Turn off your vehicle, as pumping gas while the engine is running can be hazardous.
3. Open your gas tank and unscrew the gas cap so that you can insert the fuel pump.
4. Select your method of payment on the pump. If using a credit card, swipe it and follow the on-screen instructions. If you're using cash, go inside and pay the attendant before pumping your gas.
5. Select regular unleaded gasoline by removing the pump in the corresponding holster.
6. Place the nozzle into your gas tank. Press 'Start' or pull the lever to begin pumping gas.
7. Pull up on the nozzle's lever to pump gas into your Mercedes. Read the meter on the pump as the gas flows into your tank so that you stop at your desired amount of money or gas.
8. Remove the nozzle from you car and place it back in its gas pump holster. Screw the gas cap back into your vehicle and close the tank.

How to Diagnose a Faulty Mass Air Flow Sensor

1. Connect a OBDII-type engine code reader to your car using the connection port underneath the steering wheel area. Turn the ignition to the 'on' position but do not start the engine. Let the code reader connect with the car computer to see if it will generate a code for a faulty mass air flow sensor. Confirm whether the sensor is actually triggering a malfunction code or not. Erase the code stored in the computer using the reader tools. Turn the car off and disconnect the code reader.
2. Raise the hood and locate the air filter box. Open the air filter box and pull out the old air filter. Use a shop vacuum to suck up all the debris, dust and dirt inside the filter box. However, do not poke the vacuum into the cavity going to the mass air flow sensor.
3. Turn off the vacuum and use a screwdriver to disconnect the hose clamp holding the intake hose to the bottom of the mass air flow sensor going toward the engine. Pull the hose off and place it clear of the sensor. Carefully disconnect the wiring to the mass air flow sensor itself. Use the screwdriver to carefully push the connection tab free if the wiring junction uses a snap-lock to connect. Place it safely clear of the sensor unit.
4. Use a screwdriver with a star-shape, or security Torx bit if the sensor is secured to the air filter box with screws having star-shape heads. Use a regular screwdriver if the screws are Phillips-head or flat-head style. Carefully loosen and remove the sensor screws and put them in a safe place to avoid losing them. Use the shop rag to carefully twist the sensor back and forth by hand until it comes free from the air filter box.
5. Move the sensor unit to a clear workspace. Put a shop rag underneath it and do not touch the sensor mechanism inside. Attach the spray nozzle to your bottle of mass air flow sensor cleaner and spray the sensor clean with five or six good sprays. Spray downward so the excess hits the rag underneath. Examine the wire inside without touching it to confirm it is clean. Let the unit air dry on the rag for 30 minutes.
6. Reattach the sensor, without touching the inside wire mechanism, to the air filter box and following the above removal steps in reverse order. Install a new air filter in the air filter box and close it up. Confirm you reconnected the sensor wiring, re-installed the sensor's screws, reattach the air hoses and re-tightened the hose clamps. Check for missing tools as well. Close the hood and restart the car. Let the engine warm up and drive it to check if the sensor gives off a trouble code again. Replace the sensor unit completely if it does.

How to Set the Timing on an Audi

1. Put your key in the ignition and start the engine. Shut off all accessories in your car.
2. Exit the car and place wheel chocks under the front and back tires of your car. Enter the car and apply the emergency brake firmly. Put the transmission in neutral and gradually bring the engine to a warm idle speed of 925 rpm.
3. Exit the car and open the hood to your engine. Allow the engine speed to decrease. Find the engine control module on the right side of the engine and engage the warm idle speed control to keep the engine warm. The engine control module will look like a large computer chip.
4. Attach a timing light to the battery by placing the red clips on the positive terminal before you place the black clips on the negative terminal. Attach the timing light clamps to the spark plug wire labeled Number One.
5. Shine the timing light on the pulley connected to the engine's crankshaft. Compare the timing index to the timing marks on the distributor housing. The distributor housing is connected to the engine's camshaft and oil pump. The distributor housing will have a cap in the middle of it and metal on the outside of it. The metal will have a dent or marks on it; those marks are the timing marks.
6. Ground the carburetor switch with jumper cables by placing the red clamps on the switch and the black clamps on a metal ground.
7. Rotate the metal part of the distributor housing with your hand until the timing marks line up with the timing index on the pulley. This will set the ignition time to the factory recommended ignition time of your Audi.
8. Remove the timing light from the battery and spark plug wire. Remove the jumper cables from the carburetor switch. Shut off the warm idle speed control and close the hood to your engine.
9. Enter the car and put the transmission in park. Exit the car and remove the wheel chocks.

How to Jack Up a BMW

Front Jacking
1. Park your vehicle on level ground. Turn the engine off and engage the emergency brake.
2. Position yourself so you can see under the front end of your vehicle. Look for a black jack-point in the middle of the front sub-frame, or use the sub-frame. The vehicle might be equipped with a round jack-point in between the front wheels, on the skid plate. The stock, BMW jack fits in that spot.
3. Place the jack under the sub-frame or jack point. Raise the jack until it lifts the car far enough to place jack stands under the frame. Place one jack stand on each side of the vehicle -- under the sub-frame -- for support.
4. Lower the jack until the vehicle is securely resting on the jack stands. Remove the jack from under the car. Place blocks in the back of your rear tires for extra support.
Rear Jacking
5. Park your vehicle on level ground. Turn the engine off and engage the emergency brake.
6. Locate the rear differential. Locate the adjacent U brace. Do not place the jack directly on the differential; the pressure might damage it.
7. Place the jack under the U brace. Raise the jack until the car is at a convenient height.
8. Place blocks in front of your front tires for extra support.

How to Choose the Right Truck Tire Jack

1. Open your door and look at the vehicle information sticker, usually on the door near the door jam, or on the door frame of the truck. This will list your vehicle's basic information.
2. Look for the truck's gross weight or curb weight. This can be referenced as GVW-Gross Vehicle Weight or GCW-Gross Curb Weight. This will be written in a measurement of tons such as 3.0-tons, or 2.5-tons.
3. Measure the distance in inches from the ground to the frame of your truck, or to the jack placement points, with a tape measure. A jack placement point is installed on some truck models and is usually a small protruding metal bar located on the frame at the front and rear of the truck, just near the tires.
4. Go to an auto parts store or a dealership for your respective vehicle model and order or purchase a jack that suits your measurements. As a rule of thumb, choose a jack that exceeds your weight measurements slightly so that you know for certain that it will lift the truck off of the ground.
