When is the Best Time to Replace Your Timing Belt?

May 24, 2021

An engine typically maximises multiple parts for it to function and operate. And one of its parts is the timing belt. A timing belt, which is also known as the timing chain or cambelt, is an integral part of an internal combustion engine that can connect the crankshaft to the camshaft and synchronises their rotation. This specific movement then allows both pistons and valves of a vehicle to be controlled effectively during intake and exhaust strokes of the cylinder.

Overall, the timing belt ensures that the engine can perform optimally during its whole service life. It likewise makes sure that all the phases of an engine will be carried out in precise order. All these functions of the timing belt are possible since it is often made from a reinforced rubber band that is filled with teeth or notches on its inner side.

Although the timing belt is usually located inside the motor, it can still sustain damages and problems in the long run. As a result, this specific component must be replaced immediately whenever crucial issues occur. The following instances are some signs that call for timing belt replacement.

Rough Idling

As previously stated, a timing belt has teeth or notches that allow it to carry out significant functions. However, if these teeth start to fall off, then the timing belt will eventually slip away inside the engine. Some parts of the timing belt might then fall directly into the gears, creating some obstacles to the normal operations of the engine. The engine would even stall as its components are not synchronised anymore.

Engine Misfire

Another instance where timing belt replacement must be done right away is if the engine misfires. Connected to the rough idling issue, a timing belt that seems to slip away from the gears can easily affect the synced movement of the cylinders. If one of the cylinders start to open and close too soon, the engine will misfire. And if the timing belt is not replaced for too long, the whole engine can be damaged.

Thick Smoke

While smoke from the tailpipe is normal, one that is too thick means that something is not right with the engine. The timing belt, in particular, can cause this particular issue as too much smoke typically means that the engine components are not operating appropriately. With a faulty timing belt, some cylinders will not be moving at the same pace anymore. As these unwanted changes continue, the exhaust would then let out and let in air inappropriately, generating thick smoke from its whole system.

Broken Parts

The timing belt must move at the right time to ensure all engine components work perfectly. But if its timing has become bad, then some pieces of the camshaft might get damaged. Pistons or valves might also get broken once the timing belt fails to operate anymore. Pieces of the camshaft that fall into the oil pan of the vehicle would only lead to oil pressure decline. Broken pistons or valves, alternatively, will only result in permanent engine damage if they are left unchecked for a long time.
