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.
