What should my idle temp be?
195 or 210 should be your idle temp. Your thermo might be bad, it's a pretty easy repair. I don't think you'll ever run into the problem that it runs too cold. i also don't think you need to worry about the jeep not being able to go up hills. if your serp is tight you shouldn't have any more issues.

My XJ Cherokee 4.0L runs right at thermostat temperature (195-F) yet reads 5-degrees higher with an offshore aftermarket sender from AutoZone. I've changed thermostats, no change.
