Automobile Timing Belt Replacement



The timing belt is an integral part of the internal combustion engine, and it serves a very important purpose. It is responsible for accurately timing the opening and closing of the intake and exhaust valves, which allows the engine to run smoothly and efficiently. Over time, the timing belt can become worn out or damaged, leading to decreased performance or even complete engine failure. This is why it is important to replace your vehicle’s timing belt on a regular basis.

Reasons for Timing Belt Replacement



Timing belts should be replaced on a regular basis – usually every 60,000 miles – in order to ensure that they are working properly. As they age, they can become dry and brittle, which can cause them to stretch or break. If this happens while the engine is running, it can cause serious damage due to valves being open at the wrong time. It is also possible for debris to build up on the teeth of the timing belt over time, which can cause it to slip or cause other issues with your vehicle’s performance.
