Timing Belts
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 Timing 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, but you should ask our technicians--we will
know for sure.
What Is A "Free Running" Engine?
If the timing belt breaks on a free running engine, the engine stops and you
will need a tow to the repair shop. No mechanical damage occurs and the
installation of a new belt is usually all that is needed to get you on your
way.
What Is An "Interference" Engine?
If the timing belt breaks on an interference engine, mechanical engine damage
occurs. It most commonly involves open valves being struck by the pistons,
resulting in the need for expensive repairs. In extreme cases, a replacement
engine may be required.
