A timing belt, also known as a cambelt, timing chain or camshaft, is an essential part of your carâ€™s engine. Itâ€™s responsible for the rotation of the crankshaft, synchronising the opening and closing of the engineâ€™s valves.
The timing belt has little teeth on it, and in some higher power vehicles like trucks and vans, the belt will be replaced by a chain which is more durable.
The first known use of a timing belt was back in 1954. Bill Devin invented the rubber cogged timing belt for his cars, and within ten years they were being mass produced in practically every vehicle in America.
If your timing belt fails, then it can be catastrophic for your engine. The most common failure of timing belts is wear & tear. The teeth/grooves of the timing belt become smooth over time and the belt can slip. If this happens, then the engine can suffer serious damage, so itâ€™s important to change your timing belt every 100,000 â€“ 150,000 Kms.
You can check on your timing belt yourself by simply lifting your hood. If you notice any of these flowing things then itâ€™s time to give us a call and have your timing belt replaced.
Smoothness- If your timing belt looks smooth, then it means the teeth have worn down over time and it needs to be replaced.
Cracking- An obvious sign that itâ€™s time to replace the belt is cracking. This could be because of the usual wear & tear, or an inferior or damaged product to begin with.
Glazing- This is when the timing belt appears shiny underneath, meaning that it has gone stiff and therefore isnâ€™t giving the flexibility thatâ€™s need to work properly. Try putting an indent on the timing belt. If you canâ€™t mark it, then it needs replaced ASAP.
Noise or vibration- This is an obvious giveaway that thereâ€™s something wrong with your timing belt. It can either point to a belt thatâ€™s too tight or too lose.
