This part cross-references Dayco 85046 for the same application.

Common Problems This Part Can Address

• Timing belt slack caused by a worn tensioner
• Noise from an aging hydraulic tensioner assembly
• Uneven belt loading during engine operation
• Premature timing belt wear from inconsistent tension
• Timing service issues on Toyota Tacoma, Toyota Tundra, Toyota 4Runner, and Toyota T100 engines

Installation Notes

Install during timing belt service and verify the belt path, alignment marks, and tensioner operation before engine start-up. Follow the vehicle service procedure for the specific Toyota engine application, and inspect related timing components for wear while the system is open. The part number T43210 should be matched to the exact engine and model year listed in the fitment data.
