The low side service port Schrader valve has a slow leak; however, finding the correct replacement type has been difficult to figure out.

Does anyone know the answer, and where to purchase it?

Thank you!

 

Just take the old one to a 'competent' auto parts store to match it up?
The parts store I use in a small rural town has all sorts of parts and the guy knows what part it fits by looking at it.
Mostly GM and Ford are used in the climate control service valves and connectors.
Lots of GM and Ford parts are interchangeable.

 

The schrader is actually a Volvo part: Volvo part # 6849305

I originally used a generic replacement, Santech MT0301, which lasted about a week before leaking again.Be careful there's lots of China made junk parts under this Volvo number. I'd go for OE.

Thank you!

 

Unfortunately, that Volvo part is not correct (at least for my '04 VDP) see the attached photo of the Volvo valve on left, and the old valve on the right..

There is a service kit #26782 available at O'Reilly, Amazon, etc. that has one valve that does work.

 

I'm so sorry--I didn't expect that Jag changed any of the a/c parts between years. The Volvo schrader on the left in your picture is definitely what's in my '06.

 

No worries, you were only trying to help, and it is appreciated. Just wanted anyone finding the thread to know that isn't that straight forward.

Cheers
