AC question?
Took my X-Type to an indy AC shop today to have it checked out. Not blowing cold. Their diagnosis was leaky schrader valves. They tried ordering parts for it and were sent parts from different parts houses, but none fit my car. They then surmised that the valves are part of the AC hoses system and cannot be replaced seperately. And they are only available from Jaguar. COMMENTS????

This sounds a bit odd. The AC Schrader valve is just like the schrader valve in a tire stem. I am not sure if they are interchangeable or not, but they look and work the same.
You can buy adapters that are 90 degrees that include a schrader valve in them. I have used them and just left them on the car to give me a better seal. They also make metal caps that have an O-ring in them. This too should seal a small leak.

The Schrader valve in the A/C System works the same, but sizes are different to that of the ones for tires. The A/C ones are bigger.
As for the hoses themselves, they are bent in a way that fits that vehicle. You might be able to find a company than custom make A/C hoses, but you'll have to take yours off in order to do that. Since the fittings where you connect manifold gauges are the same across all makes and models, I'm sure someone out there has the Schrader valves on their own.
Are they sure that's the problem? The compressors on these cars are notorious for failing. Not to mention if your radiator cooling fans aren't working properly, will cause the A/C not to work properly. If they used one of those sniffers, I don't think they are very accurate and can be misleading.

This sounds like a problem I had on my 2003 x-Type many years ago. One of the A/C
lines would hit a bolt from the body when the engine moved to an extreme position.
This probably happened when we hit a pot hole. The spacing was about 1/2 inch
when the car was stopped. Apparently when you would hit a pot hole the line would
hit the bolt. After years of this it wore a hole and the freon was lost.
The mechanic showed me the hole. It was a wear hole in the aluminum part of the
hose not a punch through hole. He showed the gap with the new hose installed.
The bolt that caused the problem was on some other component, I forget what,
but the offending bolt could be repositioned without any difficulty. Clearly a
factory issue but the car was out of warranty by that time.
