    Looking for some advise on what to do next. My coolant temp sensor is new, thermostat recently replace and sufficient coolant in reservoir but yet my coolant temp. is running in the high area. Any ideas why it might be registering so hot?

    Could be radiator is clogged, or fan is not engaging, couple things to check.

    What is high? Almost red? 210ish is normal. Is your fan electric or fixed on your pulley? If your fan is electric. Park the jeep let it idle till it gets to running temp (210ish) and see if your electric fen kicks on. Next step would be radiator. Make sure you're Putting 50/50 antifreeze and not straight concentrate. You'll overheat with straight freeze.
