try replacing the preasure tank and or the cap on that thing. They have a tendency to crack, and it will cause you to over heat. I got fed up with that so i upgraded my radiator to the 1992+ system, and eliminated the preasure tank all together.

Try burping like they said if it's leaking from the cap on the coolant bottle try getting the aluminum ones from macs radiators.com those plastic bottles are crap.
