Timing belt Service

A timing belt is an integral part of your car’s engine. Also known as a cambelt, it can be easily overlooked or ignored but if it fails, your engine is going to fail too! It is important to get your car’s timing belt replaced at the manufacturers intervals, and while there are no warning signs, any strange noise coming from your engine should always be checked by a professional mechanic, such as those here at Mitchell Service Centre.

A snapped timing belt can cause damage to your engine so it is always best to have it looked at and, if necessary, a replacement fitted. Your car’s manufacturing guidelines should give you clear guidance on when a timing belt should be replaced, both in terms of mileage and the age of the car.

How does a timing belt work?

The timing belt is a rubber toothed belt. The belt controls the rotation of the camshaft which controls the opening and closing of the engine’s numerous valves. The valves operation is synchronised with the position of the pistons. When the timing belt snaps, the valves are no longer synchronised and damage can be caused to the pistons.

The idler and tensioner

When replacing the timing belt, you may also wish to consider replacing the idler and tensioner as well. The timing belt idler is a small pulley that helps to keep the timing belt in the correct position. A tensioner ensures that the timing belt is kept at the optimum tension at all times, by holding pressure on the belt. They play an important role in keeping the timing belt running smoothly and need to be checked to ensure they will not seize and cause damage to the car’s engine. The general advice is to change the idler and tensioners at the same time as the timing belt.

While it will always cost to replace your car’s timing belt, the timing belt failing and damaging your car’s engine will, in the long run, cost you more. Have a look at your manufacturer’s guidelines and get it checked at your next service! Give us a call on (02) 6242 7030 to book yourself in today.
