What is the difference between a timing belt and chain?
A timing belt is a rubber belt that connects the crankshaft to the camshaft. It ensures that the valves open and close at the correct time. A timing chain is a metal chain that connects the crankshaft to the camshaft. It also ensures that the valves open and close at the correct time.
A timing belt needs to be replaced between 60,000 and 100,000 miles or a few years. A timing chain can last more than twice as long and does not require periodic replacement like a timing belt. A timing belt has some advantages over a chain: It is lighter in weight and thus makes it better for smaller engine applications. It also creates less noise than a chain.
On the other hand, a timing chain is more durable and can last longer than a belt. It is also less likely to slip than a belt.
