Timing chains are usually more durable than belts. Timing Belts and Timing ChainsĪutomakers commonly used chains to perform the required functions in an engine through the 1980s. Aftermarket timing belts that are stronger won’t stretch as much. From an engineering standpoint, OEM belts can stretch at high revs, affecting engine performance. Also, they may use better manufacturing techniques and more stringent testing. This is because aftermarket manufacturers may use superior materials to construct the belt. OEM and Aftermarket Timing BeltsĪs with many auto parts, some aftermarket components are of higher quality than OEM components. If the timing belt is worn, these items are most likely worn as well and are therefore subject to failure. As a result, you should also replace these items and save yourself problems (and money) in the future. This is because a lot of labor (and labor costs) go into partially dismantling the engine to access and replace the timing belt.

A new timing belt gives you peace of mind that your engine is running optimally and is not in danger of damage. Replacing an old and worn timing belt allows you to avoid this type of problem. When a timing belt breaks while the car is running, the camshaft no longer turns.
