I replaced the coolant temperature sensors that go to the ecu and the gauge about a year ago. yesterday my car started over heating, and I noticed my sensors were both and blackish blue/green where it was originally the brass color. I have no external coolant leaks, my t stat is relatively new (stant 180*), and I have enough coolant in the system. What would cause the sensors to corrode so much in less than a year?
