Unlike timing belts, which are made of rubber and require regular replacement, timing chains are generally considered more durable and long-lasting. They are typically designed to last the entire lifespan of the engine, eliminating the need for periodic belt replacements. However, it's still essential to follow the manufacturer's recommended maintenance schedule, which may include inspecting the timing chain for any signs of wear or damage.
The use of a timing chain in the Toyota 3.5L V6 engine provides reliable and durable valve timing, contributing to the overall performance and efficiency of the vehicle.
