Hi guys.
A question regarding cooling of LS engines.
My current setup is a LS6, with a CR racing radiator and dual 11" SPAL fans, 160F thermostat and a LS3 water pump. More than enough cooling for my setup.
However i am having cooling issues when standing still. The hot side of the radiator is hot, and the cold side is more than cool enough. This makes me belive that my fans and radiator is good enough. Without a thermostat in, it runs too cold 150ish. Which leads me to a faulty thermostat but this i my third one...
I have attached a great photoshopped picture of my setup with cold/hot arrows. My consern is that the radiator is delivering cold water to the thermostat and therefore the thermostat will stay closed, even if the engine water temp is increasing.
Any suggestions?
