This is a genuine TOYOTA timing chain tensioner, part number 1350363010, with a new part number designation of 13503-63011. Manufactured in Japan (JP), this component is crucial for maintaining the correct tension on your vehicle's timing chain. A properly tensioned timing chain is essential for synchronizing the rotation of the crankshaft and camshafts, which dictates the timing of valve openings and closings. This precise synchronization is vital for efficient combustion, optimal engine power, and fuel economy. Over time, timing chain tensioners can wear out or lose their effectiveness, leading to slack in the chain. Symptoms of a failing timing chain tensioner can include rattling noises from the engine, especially on startup, and potentially a check engine light. Replacing a worn tensioner with a genuine TOYOTA part like this one helps prevent more serious engine damage that can occur if the timing chain jumps a tooth or becomes excessively loose. Ensure your TOYOTA engine runs smoothly and reliably by installing this high-quality, direct-fit timing chain tensioner. It is designed to meet the exact specifications of your vehicle, providing a perfect fit and dependable performance.
