BMW Serpentine Belt Diagrams
Replacing the serpentine belt on a BMW is an easy matter, as long as you have the belt diagram. These diagrams are usually included on the hood or the radiator cowl, but they’ve also been printed on the inner fender, depending on what model of car you have. If you’re unable to find the correct serpentine belt diagram for your model of car, the parts store which sells these types of belts should have the diagram which they can pull up on their computer and print out for you.
Before you replace the serpentine belt on your BMW, it’s imperative that you have a diagram to follow, as the belt must be threaded correctly for it to run properly. It’s also very important to ensure you have the right diagram for your type of motor, as threading the belt according to the diagram which is wrong could result in problems. The important thing to keep in mind when replacing the serpentine belt is that the pulleys are either grooved or smooth, and this tells you which side of the pulley the belt rides on, giving you some clue as to how the belt is threaded on the various pulleys.
