Mike Howard Posted November 5, 2012 Report Share Posted November 5, 2012 I have replaced the head gasket, head, seals, thermostat, radiator cap in my truck in the past fer months. it had great heat till the head gasket went out, now it gets warm, enough to defrost windows and provide little warmth but not like it was. I have noticed the upper radiator inlet pipe is cracked, would this cause the issue? I have touched the heater core hoses and one seems to be hotter than the other, trying to run down the issue so i can get some heat in the truck again for winter.

Keith77 Posted November 5, 2012 Report Share Posted November 5, 2012 Seems like the heater core may be pluged. Try back flushing it Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle. Link to comment Share on other sites More sharing options...

Mike Howard Posted November 5, 2012 Author Report Share Posted November 5, 2012 ok i went out and reached under the dash to feel the heater core hose and found it is leaking and making the drivers side wet. my guess is the heat core is toast.

Mike Howard Posted November 6, 2012 Author Report Share Posted November 6, 2012 i just flushed the core, a few chucks came out and started flowing good, flushed it both ways 3 times, put it back together and filled it up, let it idle, water went down then filled more, has better heat now and no signs of dripping to the floor, will give it a few days and see how it goes. thanks for the help Link to comment Share on other sites More sharing options...
