Many automakers estimate the timing chain will last for the lifetime of the vehicle. The timing chain is going to last longer, in most situations, because of the heavy-duty construction. If it runs dry, it could fail prematurely. The timing chain uses engine oil as it runs through the motor. With a timing chain, you need to make sure it remains lubricated. In some cases, the tensioner or pulley needs to be replaced and the problem isn’t related to the belt at all.

When something starts to fail, you’ll hear a squealing sound from the tensioner. It doesn’t need to be oiled and it relies on automatic tensioners to hold it in place. There’s virtually no maintenance to perform with the timing belt. Additionally, the rubber material is going to be quieter while operating than the chain. On the other hand, the chain tends to be more durable but also costs more to make. The differences between the two based solely on the construction are profound.įor example, the rubber material is lighter, allowing for better fuel efficiency. In comparison, the timing chain is constructed from metal. It can also be made with neoprene or polyurethane containing corded fibers inside. The timing belt is made from strong rubber. You also want to look at the lifespan, cost of replacement and the location 1. When evaluating the differences between the timing belt and the timing chain, it’s important to think about the construction and maintenance requirements. What Are The Key Differences Between A Timing Chain and A Timing Belt? However, the lack of durability does lead to some disadvantages. The first engine mass-produced in America to have a timing belt was the 1966 Pontiac OHC. The belt was made by the Gilmer Company and the car went on to win the 1956 Sports Car Club of America National Championship. The first recorded use of a timing belt in a car engine was in the 1954 Devin-Panhard race car. Once combustion has occurred, the timing belt also ensures that the exhaust can escape from the engine. With the timing belt working as it should, fuel enters the combustion chamber at an appropriate level. It’s responsible for controlling the timing of the intake and exhaust valves. The belt connects the crankshaft and camshaft, providing the same functions as a chain. Either way, it has corded fibers within the belt to offer some reinforcement and provide tension. Some manufacturers prefer a neoprene or polyurethane construction instead. The timing belt is constructed of rubber material and it contains tooth-like grooves to act as the chain.

Failed chain can cause damage to the engine block, cylinder head and crankshaft.

Can create noise and a rough idle if stretched out.

Without maintenance, the chain can stretch and wear out.

Chain needs to be lubricated by the motor oil.

Not everything about the timing chain is considered good. In recent years, automakers have moved back to the timing chain because of the increased durability. However, the chains were replaced in the 1970s and 1980s with toothed belts that required no lubrication. Timing chains were incredibly popular prior to the 1970s, as they replaced the previous gear-driven timing setup. Without the timing chain, the engine couldn’t run. It also ensures that the appropriate amount of exhaust leaves the engine. When the timing chain has everything synchronized, the right amount of fuel enters the engine. It balances the opening and closing of valves in the engine, otherwise referred to as the exhaust and intake valves. The timing chain is needed to synchronize the rotation between the crankshaft and the camshaft. If the timing chain needs to be replaced, the repair bill is much more expensive. Yet, these can also fail, especially on some newer models with weaker chains. The timing chain doesn’t normally come with a replacement interval. For this reason, most automakers recommend changing the timing belt as part of the regular maintenance, typically every 60,000 to 100,000 miles. Any oil or coolant contamination further leads to deterioration.

However, this rubber material doesn’t last as long as most chains will. The timing belt is made from rubber, which keeps the cost lower. However, some newer cars use timing chains that fail prematurely, leaving owners with an expensive repair. Timing chains are heavier, so they normally last longer. It does degrade over time and requires replacement. The timing belt is quiet and lightweight, but it’s not meant to last a long time. Conclusion Is A Timing Chain Or Timing Belt Better?
