Gates 00-09 Toyota Tundra V-8 4.7L Tensioner Assy. Belt Drive Tensioner

This is a Gates serpentine belt tensioner assembly, designed to keep the accessory drive belt on your V8 4.7L engine properly tensioned. A worn or weak tensioner can lead to a loose belt, causing noise, reduced performance from accessories like the alternator and power steering pump, and even premature belt wear. This assembly is a direct replacement for many Lexus and Toyota models, including the 2005-2007 Lexus GS430, 2003-2009 Lexus GX470, and 2003-2009 Toyota Tundra.

Gates is a well-known name in belt systems, and this tensioner assembly is built to meet the demands of your vehicle's accessory drive. It features a robust spring mechanism that automatically adjusts for belt stretch over time, maintaining consistent tension. This helps prevent belt slippage and ensures all your accessories run at their optimal speed. When you're replacing your serpentine belt, it's often a good idea to replace the tensioner at the same time, as they tend to wear out around the same mileage.
