you might have an air bubble in the heater after all that work and you will have to get the bubble to move on.

Try lifting the top hose up higher than the block and letting it run for a while.

Were on north coast do you live

 

I took the radiator cap off, started it and ran it until the thermo opened up and started pushing the coolant through the system. I did pick up the heater line and propped it up for a few minutes with a 2x4. I did this for about 15 minutes, jeep still runs cold. I cant figure out how to get more heat out of it. Just tired of being cold. If anyone in the Cleveland area has a 258 CJ that rocks the heat I would love to check it out.

 

Yeah I Got One. Just a little south east of CLE

 

is the cowl flap closed? and drawing inside air?

 

I dont know, that is a good question. I will have to look at that. I did throw out the old heater assembly but I cannot remember what I did with the hole behind the dash. Ill get back to you on that. Thank you!

 

Maybe not what you want to hear, but....Find a stock heater and upgrade the blower motor. It will cook you right out of the cab.

 

Just did this, and my impression is that setting 2 is a lot like setting 3 with the old motor. Setting 3 is a lot like driving with the top off in the summer - I have to turn the radio up because I can't hear anything. Does it heat well? Hard to say, but it's been in the 30's out here, I've got a soft top, and it's way warmer than I remember my old YJ being given the same conditions.

 

Im thinking some kind of blockage, maybe just partial. If it were me, I would unhook both lines at the block, then flow water thru the system with a garden hose, into to a 5 gallon bucket to catch any debris. Flow water both ways. See if anything comes out.

On edit, when you say drops from 192 to 180 I assume you are reading that from the gauge, or are you using a thermometer. I would think 12 degrees would be hard to feel. 180 degrees is still pretty warm.

I got a 198* thermostat in my CJ, the heater output is around 180* so if his heater also has a 18* drop then yeah, 162* will feel lukewarm also.

If the heater was dropping the engine temp 12*, well, the heat has to go someplace, so it should be blasting out the heater core.

This is going to take some thinking....
1. heater off, engine heats up to 190*...
2. Heater on, engine drops to 180*...
3. little heat coming from heater...

Still thinking there is a lot of air in the system or something blowing air into system. Air in heater core lowers heat output. Air trapped around sending unit lower apparent temp reading in engine.

Like Lucdog says,Need to use a thermometer in radiator to verify system temperature.

 

Man, ok. Ill have to get to this this weekend then. Snow will start knocking on our door soon and I hate doing repairs in the white crap. I appreciate everyone's suggestions, Thank you.
