How to Perform Regular Maintenance for a BMW

1. Check and replenish all fluid levels if needed. If you are performing this task on your own, check your manual for fluid specifications. Fluids include oil, brake fluid, coolant, power steering fluid, transmission fluid and windshield wiper fluid. Make sure the vehicle has been off and is cool to the touch before attempting to check the fluid levels on your own. Fill fluid containers if the level is low.
2. Perform a manual vehicle inspection of all belts and hoses. Check all the hoses for leaks. Squeeze each hose; if it feels brittle, replace it. Check the clamps on each end of the hose for moisture. If the hose is wet around the clamp, tighten the clamp. If you can't tighten the clamp, replace it. According to Auto Hauz, loose belts make a high-pitched screaming sound when the gas pedal is pushed, a sign that the belt should be tightened.
3. Find the belts at the front of the engine; there will be two or more. Push on each belt at its midpoint between the two wheels. Belts should not give more than one inch. If the belt bends further than that, replace it. You can also use a tension gauge to determine if the belt is too loose and should be replaced. Repairing a car with a broken belt can be much more costly than simply replacing a belt. Let the engine cool before attempting this.
4. Inspect the vehicle visually for leaks. Look beneath the car for any dripping fluid. If you do see a leak, take the vehicle to a mechanic shop for repair. Make sure the windshield wiper blades are operational; if they are not, replace them. Make sure all the vehicle lights are working including headlights, taillights, blinkers and brake lights. Check the pressure on the vehicle tires.
