i just bought a 86 z 28 and the owner before me was very maticulis on service which was a good thing.she told me that it has a 220 degree t stat in it and the engine runs right at 220degrees.i believe oem did this for emissions but not sure of this.i looked in a chilton manual and show the car of running a 195 degree t-stat.if this is so what controls the electric fan for start and stop is it the temp sensor and if so can you purchase one with a lower control for the fan or is the fan programable thru the computer. thanks for any help
