AISIN Engine Timing Belt Tensioner Hydraulic Assembly P/N:BTT-502
AISIN BTT-500 engine timing belt tensioner hydraulic assembly for the 1998-2003 Toyota Sienna V6 3.0L and other vehicles uses hydraulic pressure to keep tension on the timing belt. It is OE engineered and manufactured.
Ticking or rattling near the timing belt cover, or oil seeping from the tensioner body, can be signs of a worn tensioner. A worn timing belt, idler pulley or water pump can be behind the same noises, so find the cause before you buy a tensioner.
Besides the Sienna, the vehicles it fits include the 1994-2001 Toyota Camry V6 3.0L and the 1995-2004 Toyota Avalon V6 3.0L, with one tensioner per vehicle.
