Factory A/C in 1967-1972 Darts

Wow... in all my time of working on the AC systems in Az temps I have never seen high side pressures like those with the factory system. My Coronet system will blow ice cold and I have never seen it over 220 PSI in all the testing I have done with it on the hottest days. I would warn this is a test that does not tell you how they maintained those input parameters and what the test setup was. It was also done by an auto AC sales company during the time when there was lot of R12 to R134 conversions going on... they wanted a reason to change out the condensers.... Just my 2 cents.

What year is your Coronet? I really like the 66-67’s and the 68-69’s. I like the 66 Polara and Monaco’s a lot too. The tail lights are really wild. I like the larger cars. There was a rust free 1966 Coronet 2 Dr hardtop with a slant six and auto in it about 5-6 years back for only $5,500 amazingly it took months to sell it.
