The timing belt is an internal engine component that rotates the engine’s cam and crankshaft, ensuring each cylinder fires at the appropriate time. Made from high-quality rubber with nylon-reinforced cords inside to extend the life of the belt, it is subject to incredible forces inside your motor and will eventually need to be replaced. Without a fully functioning timing belt, your engine will not run. AME Automotive are Canning Vale’s leading mechanics with expertise in engine repairs, tyres and wheel alignment, brakes and car servicing. Most car manufacturers have a predetermined recommendation on when you should replace the timing belt, but there are a few warning signals that a problem exists. If you experience one or more of the below symptoms, arrange a car service and have certified mechanic inspect if you a timing belt replacement.

Engine Makes a Ticking Noise

When the timing belt starts to wear out, it may create a ticking sound inside the motor. This ticking noise can also be a sign of low oil pressure within your engine or the engine not having the proper amount of lubrication, so check your oil and if the level is within a normal range, consult your mechanic to inspect your timing belt as soon as possible.

Engine Won’t Turn Over

If the timing belt has broken inside, the engine will not be able to turn over or ignite. When you turn the key, the starter motor may engage, but since the 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.

Engine Misfires

A worn out timing belt might also impact the engine’s fire rate. The belt is attached to pulleys that drive the crank and camshaft, if the it was to slip away from the gears and fall onto the camshaft, one of the cylinders will open and close too soon. This may cause an engine misfire and means the belt should be replaced immediately. If left, it may result in permanent damage to the engine.

Rough Idling of the Engine

A timing belt is constructed with teeth that grip gears as they’re rotating various engine components. If these teeth become brittle, break or fall off, the belt will start to slip away from the gears which can lead to stalling of your engine. If you notice a loss of power and rough running conditions including, odd idling and a flashing check engine light, consult a qualified mechanic as soon as possible.

Decline in Oil Pressure and Oil Leaking

If the timing of the belt is failing, it can skip and break off pieces of the camshaft and some of these pieces might fall into the vehicle’s oil pan, resulting in the oil pressure to drop in the bottom of the engine. Oil may also leak from the timing belt cover if the cover comes loose or if the gasket between the engine block and timing cover wears out, is cracked or has been improperly installed and is pinched. Leaking oil from the timing belt cover commonly results in engine overheating and can prematurely wear the timing belt. If you notice any change in oil pressure or oil leaking from the front of the motor, there could be a problem that needs prompt attention.

The timing belt is an essential component in the proper functioning of your engine. Due to its importance and the immense force under which it operates, it is essential to replace your timing belt routinely as recommended by your vehicle’s user guide. Failure to maintain or replace your timing belt can result in catastrophic engine failure which can end up costing you thousands.
