Where is the engine thermostat located on a 1996 Toyota Avalon 6 cylinder engine?
If you follow the lower radiator hose, it connects to a pipe on
the engine block. Follow that pipe and it goes towards the rear of
the motor (about 8 inches) and turns left into the block. There are
bolts there that need to be removed that hold the housing in. The
thermostat is there. Hard to get to....good luck.
