Question about 2003 Jeep Liberty
Only heat when the car is accelerating. bad thermostat? or something worse. plenty of antifreeze
I had a similar problem with my 03 liberty only got hot when I accelerated and gets cold while at stop then hot again as you drive never hot while Idle. Do what I did changed out radiator $120 and fan motor sensor $12.00 located under glovebox. All works fine now. You can have your system pressure checked but why waste $60 at radiator repair facility when the radiator only cost $120 or less new from any major distributor I assuming your fan only works on 1 and 4 as well. This is according to the parts supervisor at JEEP a common related problem for all 02-06 Liberty's so there you have it two birds with one stone.(LOL) Hope this info will help get you out of the cold. Please rate me. And if you need further assistance you can always ask me.

If your temperature of your vechicle flunctuate and doesnt stay in the middle then its the thermostat if the temperature stays in the middle you will need to flush out your heatercore

Sounds like the water pump is starting to wear out. Or the water pump belt is loose.

Make sure the plastic reservoir on the passenger side is full to the top. My daughter had the same problem on her liberty and it solved the heat at idle problem.
