Found the nuisance coolant leak on my 2.4L 99. The drivers side housing with the temp sensor was pouring fluid when I shut off the car. Went to the auto store and got a thermostat and gasket since I was going to have it off... opened it up... WTF? So found out from haynes manual that's not the location for it. Problem is it's busted so I still need to replace it and can't find any part numbers in a search. Housing is located on drivers side upper middle. It has the upper rad hose, heater core hose, temp sender, and metal pipe that should probably have the o-ring replaced.

Call the dealer for that one i think the part is like 20 or so bucks.......just tell them you need the water outlet housing that is located on the d/s of the head......they will know what you are talking about, if not there stupid.........that outlet is common on theses motors
