The timing belt is an indispensable and important part of the engine. It connects the crankshaft, camshaft and valve mechanism, and is responsible for ensuring the coordinated operation of all components. The tension adjustment of the timing belt is to maintain the proper tension of the belt, ensure the coordination of the various components, and maintain precise synchronization during engine operation.

If the timing belt is loose or too tight, it will adversely affect engine performance.

Timing belt slack

If the timing belt is too loose, the synchronous relationship between the camshaft and the crankshaft will be destroyed, and the valve will not be opened and closed on time, so that the gas in the combustion chamber cannot be effectively controlled, thereby reducing the output power and fuel efficiency of the engine.

The slack belt will also cause the engine speed to fluctuate or jitter in the idling state, resulting in unstable idling and weak acceleration, and also increase engine wear and fuel consumption.

Timing belt too tight

If the timing belt is too tight, it will increase the friction and resistance between the belt and the engine components, aggravate the wear of the belt, and cause its early failure, resulting in engine failure and shortened life.

A belt that is too tight will also increase the load on the engine, which will consume more fuel and generate more heat, thereby affecting the performance and durability of the engine.

It is precisely because the tension adjustment of the timing belt is very important to the performance and reliability of the engine. If the above situation occurs, it will bring unnecessary maintenance costs and troubles to the owner.

Therefore, the vehicle needs to regularly check and adjust the tension of the timing belt to keep it within a reasonable range. For repair shops, mastering the correct timing belt tension adjustment is not only the embodiment of maintenance technology, but also an important weight for retaining car owners.
