The timing belt is a rubber belt found in the engine compartment behind the drive belts. Its duty is to keep the crankshaft in sync with the camshaft(s), making sure of the proper timing and operation of the engine valves and therein, the engine.
. Bear in mind:
- When changing a timing belt, also replace the water pump, tensioner, and pulleys.
- If the pulleys and tensioners fail after only changing the belt, it can create valve or piston damage and result in more expensive repairs, in order to have the engine operate properly. It is therefore essential to change the whole set.
- We only change the water pump if it is driven by the timing belt (true for 60% of the vehicles).
How it is done:
- Remove accessories required to gain access to engine timing cover.
- Remove engine timing cover,checkt timing belt and pulleys for required parts.
- Remove and change timing belt, water pump, pulleys, and tensioners.
- Reinstall timing cover and all removed components.
- Start engine and check for proper engine operation and engine timing, as well as for cooling system leaks.
Follow the maintenance schedule directed by the manufacturer and change the timing belt as recommended. The timing belt drives the water pump in about 60% of the cars. The labor cost of changing the water pump is significantly 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 puts 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 don’t get be lubricated on a regular basis). The bearings wear out over time and may seize, ,making the timing belt to come off, which can cause major internal engine damage.
What common signs indicate you may need to replace the Timing Belt?
- Abnormal squeaking issuing from the timing cover area.
- If the timing belt breaks, the vehicle will not start.
How vital is this service?
Ignoring the replacement of a timing belt as a part of scheduled maintenance, could lead to major engine failure down the road. You should not wait for your timing belt to break, it must be serviced regularly.
