Are Jeep heaters just junk?

Ok. I replaced the heater core. No big deal.

I ran the motor for about 20 minutes with the heater on. It never blew hot air. Is there something else? I had the intake valve on the heater hose wide open. Fan on high. 1st knob halfway out, 2nd knob all the way out, 3rd knob in. Did I miss something?

Does your thermostat work? My brother wasn't getting heat in his scrambler. Replaced the thermostat and now the heat will roast you alive! Well not really but it sure gets hot!

I usually have to put a piece of cardboard on the radiator. Cover the bottom 1/3 of the radiator. The cardboard sets right on the bottom tank behind the grill. This makes the engine run warmer. Otherwise, you'll never get heat out of it. Just make sure you remember to pull the cardboard out when (IF??) it gets warm.... hate to overheat it.

I had the same problem when I replaced the heater core in my YJ. I let the engine warm up, but no heat out of the heater. The problem was too much air in the system. After it cooled off I topped off the radiator and it worked fine.

To bleed off air in the heater core.
1. Make sure engine is cold you don't want to get scalded.
2. Loosen clamp on upper hose at core.
3. Start engine
4. Slowly pull hose back until air expells and coolant starts to come out.
5. Replace hose and tigthen clamp.
You should have lots of heat.
