Why do timing belts fail




















The belt can become stiff if the vehicle is not driven very often and this can make it more brittle. Cars which are driven infrequently will often need to have their timing belt changed after fewer miles than cars which are driven regularly. A timing belt is a little complicated to change, since it is difficult to get to it in the engine. Therefore, the hourly rates at the garage influences a lot on the final price.

It's commonly manufactured out of high-quality rubber with nylon-reinforced cords inside to extend the life of the belt. However, it is subject to incredible forces inside your motor and will need to be replaced eventually. Without a fully functioning timing belt, your engine will not run. Not all engines have a timing belt. The timing belt is commonly found in cars and SUVs with smaller displacement engines.

When an engine has a larger bore and stroke, most automotive manufacturers utilize a timing chain system that replaces the rubber belt with a metal chain. Generally, timing chains last longer than timing belts, with some rated to last the lifetime of the car.

Most automotive manufacturers have a predetermined recommendation on when you should replace the timing belt, but there are a few warning indicators that a problem exists. Listed below are a few common symptoms that might indicate that your timing belt is wearing out or has broken — which will require a mechanic to replace the timing belt and inspect other internal engine components for damage. The timing belt is attached by way of a series of pulleys to the engine's crank and cam shaft.

The crankshaft powers the engine's connecting rods which are attached to pistons inside the combustion chamber. The camshaft operates the cylinder head valves and rocker arm assembly, which sends fuel into the combustion chamber and expels burnt gases out of the exhaust manifold.

When the timing belt starts to wear out, it may create a ticking sound inside the motor. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication. Since the timing belt is so critical to the operation of your vehicle, if you notice this warning sign, you should contact a mechanic as soon as possible.

If the timing belt has broken inside, the engine will not be able to turn over or ignite. When you turn the key, you might hear the starter motor engage, but since the timing belt operates the crank and camshaft, it will not turn over.

If the issue is due to the timing belt being broken, it may also result in other internal engine compartment damage. In many cases, the timing belt will break while the engine is running. Some of the typical damage done to a vehicle with a broken timing belt includes damage to cylinder head hardware rocker arms, push rods or valves , damage to crank bearings or the oil pump inside the oil pan.

A professional and experienced mechanic will know how to inspect all of these supporting components if the timing belt needs to be replaced. A worn out timing belt might also impact the engine's fire rate. The timing belt is attached to pulleys that drive the crank and camshaft as we've indicated above.

The camshaft, on the other hand, operates the cylinder head valves and rocker arm assembly, which sends fuel to the combustion chamber. The expelled gases then exit through the exhaust manifold. This could also be an indication of low oil pressure as well. This means when you turn the key, you may hear the starter motor engage, but since the timing belt is responsible for operating the crank and shaft, it will not fully ignite.

Oftentimes, the timing belt will break while the car is in motion. This can cause serious damage to cylinder head hardware like rocker arms, push rods, or valves. Another common sign that your timing belt is in bad shape is an oil leak. If you start to notice oil around your engine, your vehicle may be experiencing a leak, which often occurs from the timing belt cover.
