Have a 1992 c-class rv with a 454 engine. The engine will overheat 5 minutes after running. Temp goes all the way to red during that time. I have change the fan clutch, thermostat, fan and temp. Senders. The return hose from water pump remains cool and the bottom hose is warm during this time. The overflow tank is bubbling/boiling with the radiator cracked open. The fan clutch does not kick-in either. Is the radiator blocked? How do I check. Repair? This just started to happen recently.
