This is a genuine Toyota Timing Chain Tensioner, part number 13550AD010, also known by its new part number 13550-31010. It is specifically designed for Toyota vehicles, ensuring a perfect fit and optimal performance. The timing chain tensioner plays a crucial role in your engine's health. It automatically adjusts the tension on the timing chain, keeping it taut. This precise tension is vital for maintaining the correct synchronization between the crankshaft and camshafts, which dictates valve timing. Properly functioning timing chain tensioners prevent the chain from becoming slack, which could lead to skipping teeth on the sprockets. This can cause significant engine damage, including bent valves and piston damage. Replacing a worn or failing tensioner with a genuine Toyota part ensures the longevity and reliability of your engine. This tensioner is built to meet Toyota's stringent quality standards, providing durability and consistent performance. It is an essential component for maintaining your engine's timing system and preventing costly repairs down the line.
