Dayco Engine Timing Belt Tensioner Adjuster P/N:85025
Keep the timing belt taut and your valve timing in sync with the Dayco Engine Timing Belt Tensioner Adjuster 85046. It drops in as a direct-fit replacement for the 1995-1998 Toyota T100, 1995-2004 Toyota Tacoma, 1996-2002 Toyota 4Runner, and 2000-2004 Toyota Tundra, taking the place of a worn or noisy original tensioner adjuster.
A timing belt tensioner adjuster applies and maintains the correct tension on the timing belt so it tracks properly across the camshaft and crankshaft sprockets and the belt teeth stay engaged. When the original loses its ability to hold tension, the belt can develop slack, flutter, or the risk of skipping a tooth and knocking the valve timing out of sync.
If a failing tensioner adjuster is the cause of a rattle, whine, or belt slap from the timing area, this replaces it. Replace the timing belt and related components as directed by the service procedure.
