Common Repair Uses

• Replacing a worn or noisy timing belt on a Toyota Highlander, Camry, Sienna, or Solara
• Addressing coolant leakage from the water pump during timing service
• Restoring proper belt tension after tensioner wear or loss of hydraulic damping
• Correcting timing-related drivability issues caused by belt stretch or age
• Servicing interference-engine timing components at the recommended interval

Installation Notes

Verify engine code and vehicle application before installation, especially on Toyota and Lexus models with overlapping service parts. Use the timing marks during setup, follow factory timing procedures, and inspect camshaft seals and related sealing surfaces during disassembly. Because this kit is used on interference engines, crankshaft and camshaft timing must be set precisely before the engine is started.
