It should be at the end of the lower radiator hose close to the water pump side, passenger side...I forget. augh. They say the mind is the second thing to go......lol.
It not on the top hose like the sexy American cars.
its on the front behind the radiator, in front of the timing cover. it will throw you off, but anyways its cover is only about 3 inches around with 2 bolts cross ways if i remember correctly
