Evans Coolant Temps

Last time out I had no thermostat in per Evans. The cooling system was able to maintain around 185 and cool down from 220 pretty quickly at 40-50mph in the couple mile stretches I could do around my house. But it shoots up fast when stopped. That’s why Evans says the cooling systems is up to the task but I need more fan capacity.
That's good
But remember that engine needs a thermostat for consistent cooling and proper operation for several reasons. You really dont want the coolant temp going up and down while driving around. A correctly sized cooling system will pretty much "hang" on the thermostat temp rating in most driving conditions.
