Ok so I have this set right now on a car I just bought. Just to confirm and I'm sure you've been asked this a million times. But I have the two hoses coming out of the top and ito the Y block cap, vent just goes out a tube to atmosphere.then the lower radiator has the T stat in it. Not sure the temp. But it goes right from the radiator to the block. theres no bypass or anything. My car doesn't overheat but is this the right way. How does the T sat work from the bottom "cooler" hose. Should I have the lowest temp T stat in there. Or is putting in in the upper hose better. Thank you for your help.
