what can i do do get the heat going in my jeep? i just replaced the moter and the heat worked great before. now all it will do is get warm. i put a new thermostat in it and the water cirulates just fine. i have no clue..

 

what temp thermo did you put in it?...Tj

 

a 185

 

Jeeps are suppose to run on 195 thermo's thats probably why its not hot enough...Tj

 

sometimes jeeps have trouble getting the air out of the system, it can get hung up in the heater core. At the last shop that I worked at the guy that always did cooling and heating work on cherokee's always put the front lift pads under the jeep and raised the front end up about a foot or so and then burp the system like that so the radiator cap was sitting higher than the heater core. you could simulate the same thing with a jack and jackstands, do you know how to burp a cooling system?

 

what is the temp showing on the dash

 

yeah i know how to do that, but it never came to mind. thanks. it might work.

 

the temp on the dash is a problem too because a 91 has two different temp sensors on it and the 98 moter i put in has only one. there is no place on the head to put a second sensor like it requires. i need help with that too.

 

can you get a pic please i have only seen the 1997 plus so i don't know

 

ah you could just get an after market gauge to replace the stock one. so you could use the one wire hook up

 

i tried to burp the system and nothing happened got warm for a second then cold again.
