I have an 86 Z28 with the 5.0L fuel injection that i have replaced the entire cooling system, except when i was replacing the coolant temperature sensor i found another one just like it but bigger. Nobody at the local auto places know what is is either. All this has been done cause the temperature keeps rising and lowering constantly, sometimes getting up way too high before it goes down. I replaced the fan relay and everything works but not as soon as it should. Does this mystery part have anything to do with this constant rising and falling problem? I mean it should stay just under 220 right? HELP!!
