I have a question. On normal days my car always runs between 190 and 200 degrees which is fine with me. But on those 85+ degree days it starts running hotter. How can I relieve this. The car has a history of overheating, before I got the car it had cracked heads which I have since then replaced. Everything works fine now. I dont leak coolant, I have two fans running at all times, and my radiator is in good condition. How can I keep it running nice and cool even on hot days?

 

get a 185* or 160* thermostat. and use like a ratio of 10% antifreeze to 90% water. or if u aren't running A\C then 100% water with some water wetter..

 

I do have a 185 degree thermostat and run about 60% water 40% coolant.

 

Try some Water Wetter or get a 3 core aluminum radiator. Do you have a tranny cooler, that will help too.
