Serious Damage Can Write Your Vehicle Off
If the timing belt breaks while driving, it can cause significant engine damage. The valves and pistons collide, leading to bends and breaks. Often, the car is written off as the repair costs outweigh the car’s value. For modern cars, this is less likely if the mileage is low.
The timing belt is a crucial component of your car, even though many drivers are unaware of its function. Read our helpful guide to become knowledgeable about timing belts.
What is a Timing Belt, and What Does It Do?
The timing belt is a reinforced rubber belt with teeth on one side. It connects the engine’s crankshaft and camshaft, ensuring the valves open and close perfectly with the pistons. In simple terms, the timing belt ensures that all engine parts work together seamlessly without collision.
What’s the Difference Between a Timing Belt and Timing Chain?
There isn’t much difference; both timing belts and timing chains perform the same function but are made from different materials. Timing belts are made of rubber reinforced with nylon or fiberglass, while timing chains are made of metal links. Timing belts are typically found in modern cars, whereas timing chains are more common in older and high-performance vehicles.
What’s the Difference Between a Timing Belt and Cam Belt?
There is no difference. Timing belts and cam belts are the same part. The term ‘timing’ refers to the belt maintaining the correct timing order of the engine’s pistons, while ‘cam’ comes from connecting the engine’s crankshaft and camshaft.
How Long Does a Timing Belt Last?
There is no strict rule for when a timing belt needs replacement, so be wary of mechanics claiming otherwise. Generally, timing belts last between 60,000 to 120,000 miles, depending on the car’s make and model. Check your car’s logbook for the last replacement, especially if you bought the car second-hand.
Signs the Timing Belt Needs to Be Replaced
Look out for these indicators of a failing timing belt:
- High-pitched noise: A piercing sound from the engine could be the timing belt.
- Engine misfires: A faulty timing belt can cause misfires.
- Oil leaks near the timing belt: This can indicate a weakening belt.
- Visible wear and tear: Inspect for cracks or fraying.
- Engine won’t start: This could be due to a broken timing belt, though other issues could be the cause.
How Much is a Timing Belt Change?
The cost of replacing a timing belt varies depending on the car’s make and model, typically ranging from £400 to £1600, including parts and labour
