Message	Also the specs of the t-stat are to open at 170. I guess my coolant temp sensor could be bad. But it reads within spec. I have a stock Ca ECU, NA car. My experiance with failed T-Stat is overheating, never over cooling. But then again this is a Z32. I will performe some test tonight. I took some resistance readings directly off the Coolant temp sensor before I replaced the fan clutch. I will do again tonight to see there was any change.
