Car Forum / Jeep / November 2005check gauges light / Temp gauge soaring
Over the last few days I noticed my temp rising from its normal of 210 to about 222 (first tick mark to right) usually when idling at a stop. Yesterday the check gauge lights fires up and my temp reads 247 (3rd tick mark to the right). I immediately pull over and before I can kill the engine, check gauges light goes off and temp is back to 222. This happens a few more times as I make my way home. I've got no engine codes, no fuses blown, coolant is good, and fans are working properly. At this point, I'm at a loss. Any words of wisdom from the group... Thanks John >Over the last few days I noticed my temp rising from its normal of 210 to >about 222 (first tick mark to right) usually when idling at a stop.

But not knowing any of that I would check the clutch on your mechanical fan (if you have one). Basically get the engine warm and shut it off. When hot the clutch should bring the fan to a halt immediately. If not the clutch is shot and your idle temps will go up fast. I would also check inside the radiator for coolant flow if the flow is not good you may need to flush things out or possibly replace the water pump (I've seen old pumps where the impellers were corroded to useless nubs even though the exterior looked great).

Thunder Just an update........ Needed to replace Radiator - blockage and small leak Thermostat - bad Thanks for the suggestions >>>Over the last few days I noticed my temp rising from its normal of 210 to >>>about 222 (first tick mark to right) usually when idling at a stop.

Thanks for the follow up too. Drifter "I've been here, I've been there..." It could be a bad thermostat. > Over the last few days I noticed my temp rising from its normal of 210 to > about 222 (first tick mark to right) usually when idling at a stop.
