I have a 460 w/ a berkley pump. There is a faucet type valve that controls the amount of water that goes into the engine. Is this what you use to control the water temp by opening it more for cooler temp and by closing it more to raise the temp. I know it may be a dumb question but I was just wondering.
Becuase I have mine half open and temp is about 100 degrees. I dont feel comfortable closing it any more. Is there any harm by having the valve open all the way?
