Your car’s performance relies on many different components that must work at full capacity. In modern vehicles, the timing belt is a rubber band that rotates the crankshaft in the engine, allowing the valves to synchronize their movement. If this component experiences damage, it can affect the performance of the vehicle and requires an auto mechanic to replace it. If your car is not operating efficiently, here are some indications that it may be due to the timing belt. 

When Should You Replace a Timing Belt?

1. Trouble Starting

If the timing belt experiences damage or is too old, the engine won’t turn over when you start the car. This is because each cylinder must fire at the right time. If the timing belt’s rotations are off, the cylinders won’t move correctly, causing the engine to fail. While you will hear a loud, sharp noise if the belt breaks when you’re driving, it is not as clear when the vehicle is is parked. When this happens, the engine won’t start at all, and you’ll only hear the starter engage. 

2. Clicking Sounds

Before the timing belt breaks, you might hear ticking or clicking sounds coming from the engine. The belt connects to the crankshaft by a series of pulleys, and when it starts to fail, the cylinder head valves that transfer burnt fuel can lose their synchronization.

This combustion issue results in an ticking noise that an auto mechanic should immediately investigate. Without prompt attention, you can cause considerable damage to the engine, which is more costly to repair.

3. Leaking Oil

If your vehicle has an oil leak from the front of the engine, it could be due to a broken timing belt. When the rubber tears, oil can seep through. Your oil can also leak when the gasket between the timing cover and the engine cracks, as there isn’t a barrier to hold it in. When this happens, the lack of oil can cause the engine to overheat and wear down the timing belt prematurely.
