Thanks for the help. I actually limped all the way to San Francisco with the heat on and the needle just below the red. There were periods when I was in the red and had to pull over for a while or hope for a hill. I hope no damage was done to the engine.
Is a 2-core radiator an aftermarket item? Are they still avaialbe for cars of my vintage. The last question I have is would a lower temp thermostat help and are they available?
