I am assuming you have the Northstar engine.
Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.
Are you running it without a thermostat? If so,then strangely enough,this will cause overheating as the Northstar cooling system is different to most conventional systems and therefore will not help you diagnose the problem.

I would suggest getting a Hanes or Chilton book first because you have a lot of things to remove. Drain radiator, remove intake, fuel rail, alternator, AC and many wires and vacuum hoses before you remove the heads.

Hello: You add the sealer to the tank on the passenger side under the hood. I don't recommend this as a proper repair. You may create problems with reducing the flow of coolant through the radiator. The best way is to replace the head gaskets. The tank has a radiator cap on it.

i would have the head gaskets replaced, this way , you know that there won't be any more leaks, and sometimes , using the sealer, might not work as good as you need it too.
