What to know about the Timing Belt:
The timing belt is a rubber belt situated in the engine compartment behind the drive belts. Its job is to keep the crankshaft in sync with the camshaft(s), ensuring the proper timing and operation of the engine valves and therein, the engine.
Keep in mind:
When changing a timing belt, also change the water pump, tensioner, and pulleys.
If the pulleys and tensioners should fail after only changing the belt, it can cause valve or piston damage and lead to more costly repairs, in order to have the engine run properly. It is therefore essential to change the whole set.
How to Fix:
Remove accessories required to gain access to engine timing cover.
Take out engine timing cover; examine timing belt and pulleys for wanted parts.
Remove and change timing belt, water pump, pulleys, and tensioners.
Reinstall timing cover and all removed parts.
Start engine and check for proper engine operation and engine timing, as well as for cooling system leaks.
Follow the maintenance schedule provided by the manufacturer and change the timing belt as recommended. The timing belt drives the water pump in 60% of the cars. The labor cost of changing the water pump is considerably higher than the cost of the pump. While changing the timing belt, it is cost effective to change the water pump. We highly recommend changing the timing belt pulleys and tensioners. The tensioner applies pressure to the timing belt keeping it tight, while the pulleys keep the timing belt in line. These parts are sealed units that contain bearings (they cannot be lubricated on a regular basis). The bearings wear out over time and may seize, causing the timing belt to come off, which can cause major internal engine damage.

Common symptoms indicating you may need to change the Timing Belt:
Abnormal squeaking coming from the timing cover area.
If the timing belt breaks, the car will not start.
Importance of this service:
Ignoring the replacement of a timing belt as a part of scheduled maintenance, could result in major engine failure down the road. You should not wait for your timing belt to break, it must be serviced frequently.
