Customer Question

Hi Matt Scott here, I have a 2002 Jeep Grand Cherokee Overland . Engine replaced 18 months ago. New hoses etc. Car is overheating at interstate speeds varies 70 t0 85 miles per hour.. It redlines at 260 degrees. As soon as that happens I pull over and with engine running it drops back to 210 degrees in about one minute ( that doesent make sence). I have replaced thermostat. No change. Garage suspects head gasket. They have done a pressure test but no combustion leak test yet. Prior to this I got bogged down up to the frame (two weeks prior to problem starting.) No loss of water per say water overflow was low but first time checked in a few months refilled no loss. I checked oil no water hat I can tell. No emissions from tail pipe. I was wondering is it possible if fan control module could be intermitantly going bad. Garage says fan is ok but I did not check it doing hand spin test.
