timing belt types

If the timing belt were to slip or break, the consequences could be catastrophic. For interference engines, a timing belt failure can result in the pistons striking the open valves, leading to extensive internal damage. Conversely, in non-interference engines, a broken timing belt will simply cause the engine to stop running, but the risk of serious damage remains. Therefore, the timing belt's integrity and functionality are vital for a vehicle's overall health.

For instance, when the engine runs, it rotates the crankshaft, which in turn causes the drive belt to spin. This motion activates the accessories connected to the belt. Unlike older cars that used several different belts to connect individual accessories, most modern vehicles utilize a single serpentine belt, which is more efficient and easier to replace.
