This is a genuine TOYOTA timing chain tensioner, part number 1340530030, also referenced by NEW PN: 13405-30031. Properly functioning timing chain tensioners are crucial for the health of your engine. They work to keep the timing chain taut, which in turn ensures that the camshaft and crankshaft are synchronized correctly. This synchronization is vital for the engine's valves to open and close at the precise moments needed for combustion. A worn or failing tensioner can lead to a slack timing chain. This slack can cause the chain to jump teeth on the sprockets, leading to incorrect valve timing. In severe cases, this can result in serious engine damage, including piston-to-valve contact. Replacing your timing chain tensioner with a genuine TOYOTA part ensures the quality and fitment expected for your vehicle. This component is designed and manufactured to meet TOYOTA's stringent standards, providing durability and consistent performance. It is a direct replacement for the original part, making installation straightforward for qualified technicians.
