Belts, Chains and Tensioners

The job of the timing belt is to control the opening and closing of the engine's valves by rotating the camshaft and crankshaft at high speeds. We stock a wide range of durable timing belts for all engine types. It is essential to keep the timing belt at the correct tension level. Too loose and it will flap - which could cause the engine's valves to open at the wrong time and be hit by the pistons; too tight and it will put excessive pressure on the gear bearings. The correct tension is maintained by the tensioner pulleys, which should be checked regularly and replaced if worn to ensure that the timing belt is working well. There are visual signs of wear you can look for in the timing belt, such as cracks, tears, sagging, or brittleness. Additionally, you may hear a squealing sound if the belt is not rotating properly. However, the timing belt can break without warning, so it's important not to neglect replacing it according to your engine manufacturer's specifications, even if you don't notice any signs of damage. The general rule of thumb is every four years or 60,000 miles, or slightly less often.

Car drive belts are made of rubber and wrap around pulleys attached to the crankshafts of your engine's peripheral - but important - components. You will likely need to replace your drive belt every 45,000 and 75,000 miles (or 3 to 5 years). Although it is made of very durable material, your drive belt will still wear out over time. If your drive belt wears out, it can cause squealing or noises in your engine bay. If the belt breaks, your car will start to overheat and eventually break down. In addition to helping drive many essential components in your engine bay, good quality car drive belts will create less friction than worn or poor quality examples. Therefore, the more efficient your transmission belt is, the more efficient your engine will be.
