Detailed Description

This Gates timing belt kit is designed for vehicles that use a timing belt driven water pump, making it a practical choice for full timing service on the Toyota Highlander and Lexus RX400h. The belt uses a curvilinear profile with 211 teeth and a 32 mm width, while the included hydraulic tensioner and idler support proper belt tracking and tension control. The water pump and gasket are included to address the cooling system component that is serviced at the same time as the belt on these applications.

Common Repair Uses

• Replacing a worn or aging timing belt during scheduled maintenance
• Servicing a leaking or noisy water pump at the same time as the belt
• Addressing belt tension issues caused by worn hydraulic tensioner components
• Replacing an idler pulley during a complete timing system overhaul
• Restoring proper timing system operation after high-mileage wear

Installation Notes and Tips

Follow the included instructions and the vehicle service procedure for timing alignment, tensioner setup, and water pump installation. Verify camshaft and crankshaft timing marks before removing the old belt, and inspect related seals and cooling system surfaces during reassembly. Because this is a timing belt driven water pump application, replacing the pump with the belt service is the recommended repair approach for these vehicles.
