88 formula V-6, auto. Replaced the water pump, replaced thermostat (tested good), fan works as it should, new aluminum radiator installed by PO, repaired the crushed coolant tubes. I have no leaks whatsoever. If I go on cruise around town it overheats, coolant blows out the radiator cap. I'm not 100% sure the PO installed the radiator correctly. The radiator cap hits the hood when closed, could this be the problem. It looks like a 3 row radiator and i'm not sure they shaved down the lower rubber supports. The top of the radiator is pretty snug in the brackets. Engine runs very strong and no white smoke out the tailpipes so I don't think headgaskets could be it. Kinda stumped on this one.

Well, of course the radiator cap should not hit the hood when closed. It's also supposed to be a NON vented cap on the radiator. Did you properly fill the system with coolant making sure there are no air pockets?

When it blows out the radiator cap it goes into the overflow tank right?
Could be the wrong radiator cap. It needs to be "non vented".

No it just blows out the sides of the cap, and the proper fill procedure was used. Which cap should it have as far as PSI rating?

How old is the radiator? I did a 3800 swapped in to a car with one of the aluminum radiators that was put in she they first came out. No matter how I bless the car it would not run cool and coolant would come out the cap. Traded it out with a new plastic tank radiator, bled one time and no issues..That radiator also did not fit correctly at all..

Not sure on the age of the Radiator PO had no clue about fiero's and farmed out all his work, still fixing that mess. I'll check the Rad cap to make sure its correct and reinstall the radiator the proper way.
