My other beast is a Vette, and on the Corvette Forum the techs all say that the 160° stat is no good, as it does not let the water stay in the radiator long enough to cool down? Back in the day when I didn't know better, I took the thermostat out of my old 318 in the summer time.. No problems... Apparently there is an optimal temp, and too cool will cause poor mileage, screwed, plugs, etc...




Dwell time in the radiator has nothing to do with overheating. The 160 degree thermostat will not exacerbate overheating. If your pulleys are stock ratio then you need a high flow water pump or a better radiator. The fan you have is fine with stock ratio pulleys. Also, make sure your belt is not slipping. -Bob
