Product Details

Gates PowerGrip timing tensioners are engineered and tested to match OE-quality or OE-exact fit and performance. This T43284 timing belt tensioner is designed to help extend belt life by keeping timing belt tension controlled, which is critical for accurate camshaft and crankshaft synchronization. It is a direct-fit replacement for select Toyota Highlander and Lexus RX400h models, including the 2006 Toyota Highlander built June 2005 and newer, the 2007-2010 Toyota Highlander, and the 2007-2008 Lexus RX400h. This part cross-references 1354020040 for the same application.

What It Helps Address

• Timing belt slack or inconsistent belt tension
• Noise from a worn or weak tensioner assembly
• Premature timing belt wear caused by improper tension
• Timing service issues on Toyota Highlander and Lexus RX400h engines
• Loss of proper valve timing control from a failing tensioner

Installation Notes and Tips

Install the tensioner during timing belt service and verify engine timing marks before reassembly. Follow the vehicle service procedure for the hydraulic cylinder tensioner and confirm the belt tracks correctly after installation. For fitment, this part is used on 2006-2010 Toyota Highlander, 2007-2008 Lexus RX400h, and 2006 Toyota Highlander June 2005 & newer timing belt tensioner applications.
