Sorry I should have tryed to explain in last post.

Look towards the bottom of the throttle body, there is a large spring, just behind the spring is a cam that rotates against the thermal valve (small plunger that moves in and out with tensiion of spring.) If you take the spring off you can remove the thermal valve (Housing turns out of the throttle body) It has a o ring on it that detoriates causing a coolant leak.
