The car does does run hot according to the previous owner. So as part of restoring it and preserving it, I’m addressing issues to the entire car. There’s a radiator shop not far from me. It’s about 10 miles away. But what about the bent neck? Can they straighten that out or is it more cost effective to buy a new radiator. Also, what’s the mix that goes in the car? The fluid looks clear which leads me to believe it’s probably filled up with water.
