| 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, but you should ask your technician; he 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
pistons, resulting in the need for expensive repairs. In extreme
cases, a replacement engine may be required.
