Rick what are your thoughts. I have a PRC crossflow, system checks with no leaks. The gauge sender has its "own" wire. My electric fans run on a separate sender. I have taken temps with IR gun and thermometer in radiator, so I know the gauge is ready wrong. He said teflon wasn't the best thing to use for this application. Jake suggested I try this new sender, but use the Loctite stuff. If not then maybe the gauge is faulty. On CI website Jake is listed as an electrical engineer? I am putting a/c on this car and freek out when I see temps in the 212 to 230 range when its 49 degrees outside. BTW, checked my timing and I'm good there.I am hopeful this will fix the problem;if not then pull out gauges
