    Has anyone used a infrared thermometer http://ecx.images-amazon.com/images/I/41-JtdaCBeL._SS500_.jpg to make sure its not a sensor or the gauge isn't reading properly about $50 at Amazon.com

    My moms jeep wrangler is having the same problem. I replaced all the likely parts and no dice. The next part on the list that could be a possible cause is the head gasket. If it is leaking air gets pumped into the cooling system. Have the cooling tested to determine this.
