This sound can indicate low oil pressure, which can affect the timing belt. When the timing belt wears out, it can cause a ticking or clicking sound inside the engine. Engine misfiring is a sign of trouble that should be checked as soon as possible to avoid risking serious engine damage. If this timing is off, the engine will run erratically, if it runs at all. If the belt is worn or loose, it will slip and cause cylinders to open and close earlier than they should. Engine runs rough or misfiresĪ worn-out belt will affect the engine’s timing, and possibly cause it to misfire. Even though it’s difficult to do a visual or physical check, there are some signs you can be aware of that hint at trouble with the timing belt. If this chain breaks, you will often hear the crack. If your vehicle has a chain instead, though, it may make a lot of noise if it is loose. Once a failure occurs the engine will immediately stop or lose significant power. Usually, when a timing belt fails, it happens very suddenly. There is also no clear-cut sign that a timing belt is going bad. The timing belt is sealed in its own housing, which makes it extremely difficult to check on your own. How do you tell if a timing belt is about to fail? The same is true for the timing belt tensioner – it should be inspected and possibly replaced. If that's the case, it's a good idea to replace the water pump when replacing the timing belt and vice versa, since much of the same work has to be done for either. On some engines, the water pump is driven by the timing belt as opposed to the serpentine belt. It’s important to consult your owner’s manual to find the recommendation from your vehicle manufacturer. Older vehicles may need a replacement at 60,000. Newer cars can usually reach 100,000 miles before the timing belt needs replacement. If the timing belt breaks, the engine won't run and, in extreme cases, may result in bent or broken valves and damage to the cylinder head or other nearby components. Even though it’s made to last, it will wear out naturally and need to be replaced eventually, before it slips or breaks. A timing belt is subject to a lot of stress and strain as it works to keep things moving, all regulated in proper time. Timing belts are usually made of industrial-strength rubber with nylon-reinforced cords inside. Without a working timing belt, an engine will not run. A vehicle’s timing belt is a toothed belt that connects the engine crankshaft to the camshafts and choreographs the timing of the combustion process.
