Default Re: Ok so a brand new radiator and it still runs hot

Put the 50/50 mix in some empty jugs for use in the winter and switch to pure water with a couple of cans of anti-rust.

The specific heat of water is 25% greater than that of 50-50 antifreeze. For the same heat output from the engine, the water temperature increase will be 20% less. That's about the best you are going to do.
