[QUOTE="Flyer58, post: 425891, member: 18629"] Which brings to mind the coolant temp sensor probe. There's two, the front one on the water pump is for the ECM to keep your engine running smooth and the rear one by the last head bolt on the left (Drivers) side with a single wire. That back one is for your gauge cluster. They are different but can be tested with an ohm meter for resistance. I tested mine at 82 degrees F and it showed 7820 ohms. Here is the chart from the Jeep FSM for different temperatures. [ATTACH type="full"]115960[/ATTACH] [/QUOTE]
