The 2009 Toyota Tacoma comes with a timing chain in both its 2.7 L 4-cylinder and 4.0 L V6 engines. Unlike a belt, a timing chain is more durable and has a longer lifespan. Tacoma drivers who maintain their vehicles regularly should not encounter issues with the chain. However, if maintenance is neglected, the chain may stretch. Using low-quality oil, incorrect viscosity, or inadequate oil levels can lead to premature wear of the chain components or sprockets. The timing chain plays a crucial role in the engine, as it synchronizes the crankshaft and camshaft, controlling the timing of the valves opening and closing during combustion. Positioned inside the engine, the chain relies on engine oil for lubrication. Poor oil maintenance stands as the primary reason for timing chain failures.
