66 Dart 270 Radiator Cap & hoses

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.

A quote from the shop will help you decide. Might be pricey to restore that one... others on here might be able to advise on the likelihood of fixing the existing radiator.

Aftermarket options are pretty broad.. just be sure it's the correct application for the slanty.

A good flush of everything to include the heater core and block along the way.

Lots of opinions on fluids. My preference is Green fluid 50:50 using distilled water.
