Looking for information regarding engine coolant temperature as related to coolant antifreeze concentration. Given a properly functioning engine at operating temperature and static ambient conditions, in which direction would the coolant temperature shift(if at all) if the antifreeze to water ratio is changed from say 50:50 to 40:60; in other words, would the engine run slightly warmer or cooler? Would the reverse apply if the antifreeze concentration was increased?

Anyone have any charts on this information?
Thanks in advance.
