A timing belt will last from 100,000km to 160.000km ( 60,000 to 105,000 miles) depending on the make and model of the car, how it’s driven and how well the vehicle is maintained. Other factors can contribute to how long the timing belt might last, including manufacturer defects. Check your owner’s manual to get an idea of how long timing belts on your particular make and model last.
If you perform regular maintenance on your vehicle , your mechanic will typically notice timing belt wear when you bring the car in for servicing. If the mechanic suggests you replace the timing belt, it’s best to follow his advice. Doing so will save you a lot of trouble and money down the road.
Some common signs the timing belt could be wearing out include:
• Your car is spewing out more exhaust than usual.
• Your high-mileage car is hard to start.
• The engine vibrates, causing your car to shake.
• Your car shuts off while driving and spins over quicker than normal when you’re trying to restart it.
If the car bucks and stops running, it’s probably too late. The belt is probably broken or has otherwise failed. The type of engine you have will determine how much collateral damage occurs when the timing belt breaks. In interference engines, a timing belt break could cause severe valve damage and damage to other engine parts. A noninterference, also known as “free-wheeling,” engine typically doesn’t suffer as much damage. But it will still cost you quite a bit to replace the timing belt once it’s broken and other parts that were damaged when the belt broke.
While having the timing belt replaced, you should also consider replacing the water pump, belt tensioner, thermostat and camshaft seals. They’ll probably already be worn or about to wear out. Replacing them at the same time as your timing belt can save you money on labor and save you extra trips to the mechanic.
