Sounds like the radiator line are plugged. What you can try is taking off one rad hose lin 1 Side at radiator and the other at the water pump to engine Run water through lines leaving both lines open should flush all debris away may have to do it a few times. Where this runs thorugh heater core and back out. But do not use alot of presure from the hose.
