INFINITI I35 Timing Belt Or Timing Chain (2002 - 2004)

The INFINITI I35 only has engines with timing chains from the model years 2002 to 2004. All INFINITI I35 engines from 2002 to 2004 are interference.

A combustion engine relies on either a timing belt or timing chain to maintain the proper timing and distance between its pistons and the intake valves and exhaust valves in the combustion chamber.

An old or damaged timing belt is prone to failure, which could lead to catastrophic engine damage and an expensive repair bill. A timing chain is less prone to failure but should still be inspected by a licensed mechanic once the engine has 60,000 or more miles.

It is generally recommended to change the timing belt starting at 60,000 miles, whereas a timing chain is usually good for the life of the vehicle.
