Why timing belts need replacement.
What is a timing belt?
Timing belts have replaced timing chains on many of today’s engines.
Both belts and chains ensure that crankshaft, pistons and valves operate
together in proper sequence. Belts are lighter, quieter and more
efficient than chains.
Why replace the belt?
Like other components, timing belts wear out. Proper maintenance requires
belt replacement at regular intervals before they break.
Where are the belts located?
Timing belts are on the front of the engine protected by a plastic or metal cover.
When should belts be replaced?
When a timing belt breaks, the engine stops. Replace belts before this occurs.
Most manufacturers provide a suggested service life and replacement schedule for
this critical component.
How do I know if my car has one?
Your vehicle manual may tell you, or, come in and see us and we will check for you.
CAUTION: If the timing belt breaks on a free-running engine, the engine stops and
you will need a tow to the repair facility. No mechanical damage occurs and the
installation of a new belt is usually all that is needed to get you on your way.
If the timing belt breaks on an interference engine, mechanical engine damage occurs.
It most commonly involves open valves being struck by pistons, resulting in the need
for expensive repairs. In extreme cases, a replacement engine may be required.
