Re: Thermostatic switch problem

Thanks for the suggestion. I think I have only a partial understanding of this. I presume a preset thermostat would just keep the evaporator from freezing, cycling the compressor off if it gets too cold? This would be wired into the hot wire to the compressor as an on/off? At that point, would my on...

Thermostatic switch problem

I am working on a 66 Jaguar Mk10 with a Delanair system. I posted here with some questions in 2020, but didn't get very far, as the car turned out to be completely derelict mechanically. So now after a few hundred hours of work including new drivetrain, brakes, suspension, fuel and cooling systems, ...

Re: Delenair system on vintage Jaguar

I'm liking this more and more. I actually did a shaft seal on a York Mini once, and I think it's the same, so I'll do that, flush and put in the right oil, change the clutch coil. This has flange style ports, the suction side with a rotolock, the discharge none. For R-134a, do I replace those? I wan...

Re: Delenair system on vintage Jaguar

So, I have a "complete" shop manual for this system, but parts diagrams are a bit limited. It does not show a screen on the expansion valve, but that doesn't mean there isn't one. Can I tell by looking at it whether one is present? I'm assuming the valve has to be disassembled to remove it...

Re: Delenair system on vintage Jaguar

I believe you are right. I was chatting with a friend who is a retired airplane mechanic. When they switched the fleet of planes over to r134a, all they did was to change the compressors and driers, and recharge the system. He said they all worked and continued to do so for 20 years. I'm sure the ad...

Re: Delenair system on vintage Jaguar

Yeah, I see that shop air is a problem. If I were to go R-12, I might have to get a pro involved. No dedicated AC shops in my neck of the woods.

Re: Delenair system on vintage Jaguar

Pretty tough to find the R-12, I think, but I'll have a look. I would definitely want to be sure the system was absolutely tight before putting any of that in. Could I just use compressed air to check?

Re: Delenair system on vintage Jaguar

Thanks for the reply. No personal experience, but I have read that old hoses are impregnated with oil and, assuming they are otherwise sound, can work as a barrier for 134a - any opinion about that? There is about 35 feet of hose in this car! As to the condensers, you mention best practice, but that...

Delenair system on vintage Jaguar

Hi, new to the forum here. I'm looking for help in resurrecting an old system in a 1965 Mk10 Jaguar. The Delenair system is complete, consisting of a York style compressor, dual condensors and drier under the hood, the rest of the hardware trunk mounted and blowing air into the rear parcel shelf. Th...
