What Is the Difference Between a Timing Belt and a Timing Chain–And Why Is It Important?

The timing system is a crucial part of the modern internal combustion engine. Depending on what kind of engine your Subaru has, it may be equipped with either a timing belt or a timing chain. These two parts serve the same function, but require different attention. A timing belt is rubber-based, and will need to be replaced at certain maintenance intervals. A timing chain is bulkier and louder; however, it does not require replacement. Though a repair might be necessary in some rare occasions, most timing chains last for the entire life of the engine.

What Else Do I Need to Know About the Timing System?

Whether it’s a belt or a chain, the timing system is absolutely critical to the functioning of your vehicle’s engine. The system synchronizes the rotation of the crankshaft and camshaft, allowing the valves in the engine to open and close at the right time. If the system fails, it can lead to catastrophic destruction of your engine. If your Subaru has a timing belt rather than a timing chain, it’s necessary to get it changed at the recommended interval.
