Earlier, you said coolant flowing too quickly through the radiator can cause overheating. Now you're saying it's the cavitation from the pump moving the coolant too quickly that causes the overheating. Which one is it? Both?
He doesn't KNOW. He just repeats what he finds that matches his thinking.
I've made it clear. You need flow. Air flow. Coolant flow. I MUST run a thermostat or I couldn't get coolant temp up. I can run, WITHOUT a fan and no thermostat, but I'd be lucky to get 150 degrees on a hundred degree day.
I did the research in 1984 fighting cooling issues. The **** being said in this thread was wrong back then. A big, two core radiator, a good quality, high flow pump, and overdrive the water pump (just like the factory did) and you can cool anything.
BTW, one of the reasons (there are many) I switched to Evans coolant is it requires no pressure to cool. I run a 2 pound cap. It's easier on everything. They also have the BEST technical help on the phone you can get. And Stewart Components. You call them, and they will tell you the truth. They also have the best thermostats out there.
