Engine Timing Common Faults

What is it?

The timing belt is the belt that controls the camshafts in your engine, opening and closing valves at just the right time for smooth operation. The timing belt has teeth that turn the camshaft in time with the crankshaft.

Where is it located?

A timing belt is the ribbed belt that is placed in a specific configuration along one side of your engine to keep the crank and camshafts timed properly. Essentially, it keeps the top half of the engine (cylinder head, valves) in sync with the bottom half (crankcase, pistons).

Indications of faults:

A high-pitched sound

As the timing belt wears out, it starts to produce a high-pitched shrieking or whirring sound.

Visual damage

You can also access the timing belt and inspect it visually. Spots of oil or coolant are signs that the belt is wearing out difficulty starting up. Timing belts that aren’t working will cause your vehicle to have a hard time starting up.

Common faults:

Misalignment
Excessive load
Weak drive structure
