Idler Pulley Sub-Assembly

About this product

The Idler Pulley Sub-Assembly (#16603-75022), an indispensable part of the Engine-Fuel category in the Timing Gear Cover & Rear End Plate system, is primarily responsible for maintaining tension in the timing belt. This keeps the engine's valves and pistons in synchronization, allowing the engine to run smoothly. The pulley rotates on a bearing; over time, this bearing may wear down, potentially causing the pulley to malfunction or break. Hence, periodic replacement of this critical component is necessary. Failure to do so could lead to the timing belt slipping or breaking, which could result in severe engine damage. Choosing genuine Toyota Autoparts for replacements provides compatibility with your vehicle and is backed by Toyota's genuine parts warranty. In the grand scheme, a well-functioning Idler Pulley Sub-Assembly (#16603-75022) enhances the overall efficiency of your engine, thereby improving the performance and safety of your vehicle.
