HELPPPPPPPPPPPPPPP Heater Core or not
Hi All,
First timer on this site, I've read all the heater posts and a little confused,
I have a 1995 F-150 P/U the hose coming into the heater core is very hot
the return hose is hardly warm, I tried to flush with a garden hose I seem to get some flow do I replace the core or is something else a possibility.
Thanks in advance
ps very little heat coming out turn on fan it goes cold

First you have to cut the hose that doesn't go to the water pump and install a flush T. Open the petcock at the bottom of the radiator and remove radiator cap. hook hose onto the flush T and let the water flow like crazy for 15 min with the engine running. Stop engine let all the resting water drain. Turn the water on again for 15 and let the engine run.
Disconnect the hose, close the petcock and fill the radiator with antifreeze with the engine running until it is full.

O, yeah it isn't the heater core it is air in the cooling system. If flushing it doesn't help hook a coolant pressure tester up and see if it holds. If not you might have a leak or a blown head gasket.

Did you hook a coolant pressure tester up to it and made sure it had no minor leaks, possibly a head gasket?
One other thing my teacher said. If you take off the hose that goes into the overflow tank, stick it in a clear pop bottle with some water in it. Turn the engine on and if it bubbles your head gasket might be bad.
