BMW 3 Series Timing Belt Or Timing Chain (1983 - 2026)

Engine timing belt and timing chain components

From the model year 1983 to 2026 the BMW 3 Series has various engines with either a timing belt or a timing chain. However, all of its engines are interference.

Scroll down to see specific data for your model year below.

The timing belt (or chain) maintains the proper synchronization between the various engine components in a combustion engine.

If the belt or chain stretches or breaks, it can lead to catastrophic engine damage.

Timing belts have a recommended replacement interval, while timing chains are generally rated for the engines lifetime, although they need to be inspected occasionally.
