First, we need to know what using a timing belt vs a timing chain kit will do to our car. Quite simply, they both perform the same function, which is to synchronize the rotation of the crankshaft and camshaft so that the engine's valves open and close at the appropriate times. They work in the same way, the only difference is their shape and the material from which they are made. The question is which is better?

Timing belt or timing chain?

This is one of the most common questions asked when buying a car today. It's no longer a question of comparing timing belts to timing chains, it's about knowing how good the engines are on both sides. Why is that? The short explanation is that the technology has advanced and modern engines work better on one system or the other. The problem may be with the engine, not the chain or belt itself. At least, in most cases.

The question "Which is better?" can never be answered. Both systems are constantly being further developed. For a while, automakers again started moving away from chains, which had too many frictional losses. There are many options.

The easiest way to know if your engine has a chain or belt system is to take a quick look at the engine. If it had a plastic cover on the front, it would run the timing belt, since the timing belt would run dry and wouldn't need more protection. However, if it has a sealed metal cover (to keep oil from leaking), then it's a chain system.
