Re: 1988 GTA Overheating Options

Well, in a GTA, you would see "normal" temps between 180* and 230*. The 350 cars would have had twin electric fans, and they come at at two different temps, based on sensor input.

The air dam, while essential on a GTA (it has no grille, all air has to be forced in via the air dam from underneath), it should not be needed for cooling on a '66 Chevy pickup with it generously sized grill in front of the radiator.

As discussed earlier in this thread, there are aftermarket thermostats that allow for a cooler running engine, when pared with fan switches that can take advantage of that thermostat around town.
