The timing belt is a crucial component of your car’s engine which enables the rotation of the cam and the crankshaft in perfect sync. It ensures that the rotation is precisely timed so that each cylinder of the engine fires at the right time for a smoother operation. As a heavy-duty component, the timing belt is made from high-quality rubber reinforced with nylon cords inside, which prevents it from snapping when subjected to recurring stress and high rotational forces.

Any damages to the timing belt can weaken it, and this affects the performance of your car directly. If the timing belt breaks, it can actually cause your car engine to fail, sometimes leaving you helpless in the middle of the road. Fortunately, a failing timing belt exhibits certain symptoms that you can look out for. If the timing belt is faulty, you need to take your car immediately to an auto repair service and have it replaced. Some of the crucial symptoms of a failing timing belt are listed below.

Engine Misfires

A failing timing belt can cause your car engine to misfire, which will directly affect its performance. A misfire will leave the combustion incomplete, which can cause irreversible damage to the engine and a general decline in performance. A worn out timing belt can cause the gears to slip during rotation, which disturbs the timing of the camshaft. Due to this, the cylinders will open or close irregularly, causing the engine to stall and lose power while accelerating or idling.

Increased Exhaust

The amount of smoke emitted from the exhaust of your car can determine the condition of the timing belt. Too much smoke with dark coloration is a symptom of a failing timing belt. This occurs mainly because a worn out timing belt will cause the camshaft to become improperly synchronized. This results in the inlet and outlet valves not opening and closing at regular intervals, which affects their normal operation during each stroke of the piston. Due to this, the amount of smoke produced by the engine will be much higher.

Ticking Noise

A ticking or a clinking sound is produced when the timing belt of your car’s engine is faulty. When the timing belt is worn out, it can result in slipping of the gears, which can result in the improper timing of the crankshaft. Timing belts that are about to fail or are worn out excessively produce a clinking sound along with a general decrease in performance.
