1995 Jeep Grand Cherokee Laredo; 130K miles; V8 4x4; had a new water pump and thermostat one month ago. Question: I've only had this vehicle about three months...and I can't say that I FOR SURE noticed before, but I think that the temperature gauge was (and should be running) around the 210 mark on this vehicle (250-260 is the red zone). In the last week, it has started running in the 230-240 range. 1) what is the normal operating range, and 2) what should i have checked out? thanks guys!
