What’s a Cambelt?


The most important maintenance item in your vehicle is the engine’s Cambelt (also known as a Timing Belt). A Cambelt is often ribbed and is placed in the car’s engine to keep the camshaft and crank timed as it should be. For proper timing, the belt is placed in a very particular arrangement along one side of your engine. For the record, the Cambelt is designed to keep the bottom half of the engine (pistons and crankcase) in sync with the top half (valves and cylinder head). It is an essential item.

Replacing the Cambelt is vital since it does not last a lifetime. It is a car part which if not replaced after prolonged use – as per your manufacturer’s recommendations – could cost you a lot of money in engine repairs. Regardless of the Cambelt being expensive, it is essential to have it installed. To avoid any nasty surprises in your engines car, have your car’s Cambelt checked annually at the very least.

Overtime the Cambelt will stretch and as a result the engine timing may get delayed. Tell-tale signs of a delayed engine include a lack of power and slow pick-up. And in some instances when the engine is idle a rattling noise can be heard coming from the Cambelt area, this is a sign that the belt may have stretched, however the noise disappears when the engine is revved.

Cambelts can also snap and if it does it can damage your car’s engine. The Cambelt is connected to the camshaft and the crankshaft, so if the belt snaps the turning momentum of the crankshaft that the pistons are attached to will hit the valves in the cylinder head and seriously damage your engine. Put another way, if the timing belt fails to properly function, the valves and pistons in your car will begin to collide repeatedly, more than a hundred times a minute, smashing into one another, causing irreversible damage to the engine. This is why it’s so important to have the Cambelt checked annually at the very least.
