Question about 2003 Jeep Liberty
Does the Jeep have electric radiator fans, or is it a conventional engine pulley mounted fan?
Your description sounds like fan failure, wherein the engine overheats when stopped or moving very slowly, due to not enough air being moved through the radiator to cool it down.
This can be confirmed by sitting stopped until the temperature goes up and then driving at normal road speed... if the temp comes back down, this is the problem.
With electric fans, this can likely be caused by a bad fan temp sensor, bad fan motor, bad fan relay, or by a wiring problem...among other possible causes.
With a mechanically driven fan, this can be caused by a bad fan viscuous clutch, missing fan shroud, or possibly loose belts.
A bug/debris clogged radiator will exacerbate the problem, whichever type fan you have, so a trip to the self-serve carwash to clean the radiator is not a bad idea, either.
Hopefully this will help and get Mom off your **** for breaking her car. Let me know how it goes or if you have more questions, and GOOD LUCK!!!
