Default overheating help

i took my 84 vette to get diagnosed for possible overheating. the mechanics said i needed a new raditor and was the cause for it to boil over because my radiator was blocked,so i replaced it with a new radiator..and it wasnt boilin over any more but it feels like its still overheating cause the upper hose would get real hot and full of presssure and my check engine light comes onafter driving for just 5 mins.and also my exhaust coming from the engine would get red hot ..im lost helpp!!!!

Red Hot is a big problem. I would not run the motor any more until you find the cause. Is the water in the radiator moving? I would remove the thermo stat and see if the coolant moves thru the system,seems you have a blockage somewhere,but don't let it get that hot before you shut it off!

With a car that old you'll have to got thru the whole cooling system and bring it up to new.
Fans, thermo, belt, water pump, etc.
