Dayco Accessory Drive Belt Idler Pulley P/N:89057
Dayco 89154 accessory drive belt idler pulley for the 2000-2009 Toyota Tundra V8 4.7L and other vehicles routes the drive belt along its path on the engine's main drive.
A squeal, chirp or grinding from the belt area, or a pulley that feels rough or loose when turned by hand with the engine off and cool, can mean the idler pulley bearing is worn. A worn belt, a weak tensioner or a misaligned pulley can be behind the same signs, so find the cause before buying.
The 2000-2009 Toyota Tundra V8 4.7L, the 2003-2009 Toyota 4Runner V8 4.7L and the 2009 Toyota Sienna take this pulley, and so do other Toyota and Lexus models. Open the Buyer's Guide tab to check your exact model and engine.
