I drove mine...I'm not much for driving mine in the winter...Deer season is about as late as I want to go. However, I have just replaced my cooling system, and have been fighting it a little bit. First was a hole in the steel heater tube, so I replaced that. THEN it snowed, so no jeep (I don't drive it in the winter to preserve what solid steel I have left). Well, last week, we didn't get any more snow and it warmed up and rained this weekend. The rain should have washed most of the salt off the road, so I took the jeep out. First trip it was running about 240 on my monitor (torque app). Got it back home, let it cool, and topped off the radiator. Let it warm up again, without the rad cap on...watched the app and the coolant started flowing through the rad right around 197 (so I know the thermostat is opening). Squeezed the upper hose a few times, topped up the radiator, and put the cap back on. Went for a drive and the temp stayed between 202 and 194...PERFECT, Finally.
Going to drive it to my hockey game tonight, then probably put it away for the winter.
