First of all 50/50 coolant/water ratio is way to high. I wouldnt use any more than 30% coolant, I would actually use about 20-25. Here in fl I use 10% coolant. Coolant will retain the heat more so than the water will. Try reducing your coolant ratio a little bit, and also check the thermo. Check for any leaks also, as the cooling system will only work correctly if it is pressurized.

Are you nuts??? LOOK at his location.. He NEEDS a 50% or close to it with the temperatures he could encounter in HIS area... Also the effect of 50% vs 30% is VERY small on the temp it would run.. I RUN 50% in TEXAS and we have 106 degree days in the heat of summer with 100 percent humidity.. WITH no overheating problems..


As for his problem it sounds like he has the thermostat in backwards (most likely) or a bad new thermostat(not as likely) , or a air pocket.. (make it easier to get air pocket out of system by drilling a small 1/8th inch or so hole in the edge of the thermostat.. )
