Understanding the inner workings of your car, particularly the difference between a timing chain and a timing belt, is important for maintenance and vehicle performance. Both components play a key role in ensuring your engine runs smoothly, but they differ in material, durability, and lifespan. Timing belts are typically made of rubber and require regular replacement, while timing chains, made of metal, often last much longer, sometimes the life of the vehicle. Knowing which system your car uses can help you stay on top of maintenance and avoid costly engine repairs. This guide will break down the key aspects of timing chains and belts, helping you make informed decisions about your car’s upkeep.
