The timing belt is attached to pulleys that drive the crank and camshaft as we've indicated above. Engine misfiresĪ worn out timing belt might also impact the engine's fire rate. 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 oil pump inside the oil pan.Ī professional and experienced mechanic will know how to inspect all of these supporting components if the timing belt needs to be replaced. In many cases, the timing belt will break while the engine is running. However, if the issue is due to the timing belt being broken, it may also result in other internal engine compartment damage. Obviously, if the car won't start, a phone call to a mechanic is usually the first step. 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 timing belt has broken inside, the engine will not be able to turn over or ignite. 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. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication. When the timing belt starts to wear out, it may create a ticking sound inside the motor. 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. The crankshaft powers the engine’s connecting rods which are attached to pistons inside the combustion chamber. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. Listed below are a few common symptoms that might indicate that your timing belt is wearing out or has broken – which will require a local ASE certified mechanic to replace the timing belt and inspect other internal engine components for damage. 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. Generally, timing chains last longer than timing belts, with some rated to last the lifetime of the car. 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. The timing belt is commonly found in cars and SUVs with smaller displacement engines. Without a fully functioning timing belt, your engine will not run. However, it is subject to incredible forces inside your motor and will need to be replaced eventually. It's commonly manufactured out of high-quality rubber with nylon-reinforced cords inside to extend the life of the belt. The timing belt is located under a timing cover and is in the front of the engine. The timing belt is an internal engine component that rotates the engine’s cam and crankshaft in sync and ensures each cylinder fires at the appropriate time.
