Where are all the running hot posts?

It's a factory AC car with the factory system but 134a.

If I don't shut off the AC before it gets to 210 it will overheat.


I can't imagine everyone with an AC car in 1973 doing that.

I just re-read my post, and I noticed that I came across as a total ***, I apologize for that. I misunderstood the direction of your question.

Are you running those horrid accordion hoses to and from your radiator?
What condition is your water pump in?
What condition is the radiator in?
Water/antifreeze mixture?
Thermostat issues?

When I replaced my radiator, I mocked up the hose path with a coat hanger and figured out the best shapes for hoses. I went with bent silicone hose sections with a lumen the diameter of the largest hose fitting and stepped down to the radiator fitting diameter at the radiator. A larger diameter pipe will offer less resistance, less pressure which is good in my eyes.

Also, at a bend, go with two 45* bends rather than a 90* bend.
