Challenger with 582
New to the forum and trying to get my challenger fit for flight. I have a 582 blue head with the sheer technologies radiator. Can someone help me understand the procedure for removing coolant? Im having a slight overheating issue and i'm not sure of the coolant to water mixture, so I was going to change that out. I'm on the east coast of Canada so will need to be a mix fit for freezing weather.
Thanks
