Why not do it the right way and vac it down and see if it holds a vacuum???
I disagree with using compressed air to leak test an A/C system.. it adds moisture to the system even if you have an in-line filter dryer. Nitrogen is a better way to go when pressure testing an AC system. IMODon't feel too bad about your cost for both cores..I spent $400. just to have my heater core rebuilt 2 years ago.
A handy tip if you're wanting to save some money fooling around with old and unknown A/C systems: Leak test with compressed air (approx 120 psi). A lot cheaper than Freon.
Then you are most qualified for the task, my son...completely rebuilt a French car with hydraulic suspension and an Italian engine..
That’s the plan.....after new evaporator is in.Why not do it the right way and vac it down and see if it holds a vacuum???

I agree compressed air is a meatball method, but if the system is empty and you've got no idea of how long and why it's empty, why waste freon? As for moisture in the system, an hour or so at a 30" vacuum should boil it out. Nitrogen would be nice but not everyone has it. Most people have a compressor of some sort available.I disagree with using compressed air to leak test an A/C system.. it adds moisture to the system even if you have an in-line filter dryer.

Thanks! That’s what the meant... replace the rubber part of the hoses using the original fittings. Even NOS hoses are 40+ years old at this stage of the game.More than likely you will have to have your original hoses rebuilt. Any hydraulic hose shop can repair it. They will reuse the original fittings/ends.
I had mine rebuilt with a 24 hour turn around at Benz Hydraulics in Bear, Delaware.
As promised, ATC working with new amplifier......
Warning: NOT VERY EXCITING.
Oh noooooooo!Cool. Now you're the go to guy for Formal ATC II.
