SO after recently getting rid of the defective oem tstat for a stant, it all behaves much better and runs significantly cooler. This last weekend was a superhot though at 105 outside. Took about a 30 minute highway run to friends and monitored the coolant temp to be safe. At 70 mph it crept up to just over 220 and I didnt hear the fan so much. Pulling off highway, with lower rpm and city street fan comes on right away and I can hear it easily.Temps also drop down quickly to about 208/210.
Thinking on it, I do believe that I dont hear the fan as often running at high rpm on highway. Is this normal? The load definitely heats the engine up, and I would prefer the fan came on and kept it at 210 ish. I am thinking that may be the normal Control behavior, just like when I am on city street, the temp may be near 200, but if I give it gas off a light the fan will ramp up for a few seconds. It seems to be trying to balance fan to load, more than temp.
