I'm COLD. NEED HEAT. GOING MAD

[Figuarus]

OK. So i'm gonna close this one out since the original issues has pretty much been fixed. I also swapped the 180 thermostat back in, and the engine is running a lot cooler, but still giving me plenty of heat in the cab.

If anyone else is having this problem, I'll add the basic run through of what I did for posterity.

1.) Check for Coolant level. add if necessary.

2.) Check for leaks

3.) check heater hose connections. the smaller 5/8 hose runs from the manifold to the small pipe on the heater core. the 3/4 hose is the return line.

4.) If any part of the cooling system is opened, make sure all the air is out. You may have to remove the core from the airbox and let it hang low to allow air to escape. If you have a pressure tester, I think you can skip that.

5.) Check fittings, core, and radiator for obstructions. any rust, lime, scale,etc will cause low/no heat conditions.

6.) If your thermostat temp rating is too low for the ambient temp, you will not get enough heat. I guess the recommended rating is 195 in the winter, 180/160 in the warmer spring and summer months.

7.) Extremely cold situations may call for you to install a winter guard. Cardboard works well.

8.) If all else fails, or if you have enough blockage in either the core or the radiator, replace.

I kept my core, and am going to attempt to run CLR through it and see if it cleans up a little. It's an original Harrison copper core.


Thanks for all the help guys! I really do appreciate your patience with me!
