Hello, a month ago I bought a 64 impala 425hp 409 car. I’ve noticed that in the few short runs ( 20 miles or less) I have made with it that the coolant temp is running at 210 degrees. This car has an electric cooling fan with a shroud that covers the radiator except about 3/4” on either side of it . It runs great. Is this too hot for this engine to run?
