Many of the parts in your car’s engine are durable metal, but there are other integral parts that can wear out much faster, like your timing belt. When there is a problem, or the timing belt has reached the end of its lifespan, work with your auto parts store to replace it as soon as possible. This critical piece of equipment needs to be working perfectly to ensure your vehicle is safe and roadworthy. Learn more below, with this helpful guide to timing belts.

What is a Timing Belt?

Timing belts are made from rubber and nylon are responsible for making sure the valves in the engine open and close at the right time. It turns the camshaft in time with the crankshaft, ensuring that each cylinder is firing when it should be. A faulty belt means that valves will be open at the wrong times, preventing your engine from running smoothly. Timing belt problems can also cause major damage if they cause the pistons to collide with the valves.

How to Tell When it Should be Changed

The lifespan of a timing belt is between 60,000 and 100,000 miles. This means replacing your belt every four or five years, but some modern belts now last longer. Check your manufacturer’s manual for specific information on your vehicle’s timing belt. If you notice any of the following signs, work with a mechanic or auto parts store to address the problem immediately. 

Unusual Sounds

A damaged or worn out timing belt causes strange squealing noises. These noises can occur at any time, including during braking or accelerating. Squealing can indicate that the belt is about to break, which could lead to significant damage. You might also hear ticking sounds when the belt is wearing out.

Low Oil Pressure

Wear and tear will eventually cause the teeth on the belt to break and fall off. Pieces of the teeth may then fall into your car’s oil pan. This reduces the oil pressure in your vehicle, and you should notice the reading change on the gauge found on your dashboard.

The Engine Misfires

A faulty timing belt inevitably throws the timing of the engine off, which causes it to misfire. The pistons won’t be controlled properly, and cylinders won’t open at the right time because the belt is slipping. Engines misfire for many different reasons, and you should contact an expert whenever you notice it happening.
