Is it possible your son got the wrong water pump?

I think when you said BOOM it overheats, I think you may have a cracked head or a gasket gone bad. and when it reaches the right temp to expand the head metal the crack opens and cumbustion gasses ecape into the cooling, and yes BOOM it overheats all of a sudden at the snap of the fingers. This is extremely hard to find. Remove the heads and have them ultrasonicly tested at a performance shop. Good Luck

i own a repair shop,and you need to check the radiator on it,to see if the bottom of it is getting stopped up,any blockage at all in it will make it over heat a little ,and until its cleaned out it will probably get worse on it also,if it has been ran real hot,there's a chance it may have a bad head gasket on it,this can happen anytime one gets a little hot,especially if its got a few miles on it,good luck,i hope this help,s.

You may need to flush your cooling system. The pathways for the coolant in your engine are about half the diameter of a pen. Over time and especially with the age of your vehicle those pathways get clogged and need to be flushed out. Just about every garage can do it. Just ask for a cooling system flush and have them check your radiator for heavy deposits or massive leaks.

Go to a n.a.p.a store and ask for a block testor kit I'm not sure what they cost but, if you follow the directions It should tell you weather of not your getting combustion gasses in the cooling system, then you can rule out head gaskets or cracked block.

i am a pontiac tech. Grand am's, Grand Prix, and Bonn's with a 3.8 v6 are famous for a leaking intake gasket. Head gaskets shouldn't be the problem.

Agree with Bat & Dodge man, experienced pontiac owner here, I've owned three cars in my time, and all three were pontiacs, 1 grand prix, 1 grand am, had trouble, and I must say, The only trouble, i ever had was the cooling system. My present ride, a firebird, hasnt had a problem yet! knock on wood.... but, pontiac has always been good to me

how often was it flushed in the last 12 years? may need good flush with hot chemicals or new radiator...R U sure the fan is running..if it needs a tune up it can run so bad the computer messes up timing.. clogged cat converter can cause over heating

Does the electric radiator fan engage? Do you see any steam while it's overheating?
These cars, or their guages can be misleading. Also, it's possible a sensor, somewhere in the heating/cooling system, is faulty.

If it's overheating quick it kinda sounds like air still in lines.Did they bleed it while cold?Makes me wonder.
