BMW 3-Series E21 (1977-1983) Filters & Belts - Belts
Belts
A belt is used to drive or power the accessories that are run off the engine. It is powered by the spinning of the crankshaft and can be used to power the alternator, power steering pump, etc. It is a good idea to check your belts for cracking or dryness. Replace them before you get stranded, get two and keep a backup in the trunk.
