Title: AC Filler Valve Leakage
Post by: polilara on 02 May 2024, 12:56:55
Had today AC-service (Y26SE), checking leaks and changing the refrigerant liquid etc. All ok except we found that the lower filling valve in front of the car started to leak.

Took a closer look and found that the leaking one has not a Filler Valve (inner part) like the other in the rear. So in rear the valve is like a tyre valve or like part No. 6 in the enclosed pic. But the front one is just a hole. In the hole there is something which you can push and increase the leakage but leak does not stop when releasing. Acc. to 7zap I seem to have construction referred as part 2. I guess that in this construction the separate inner part really does not exist. Any experience about this? In the plastic protection gap there is a rubber seal, If I tighten it I think that the leak stops. Strange, do I need the whole Part 2 or did I understand this in a wrong way?

You can replace the valve on its own, I think it's discussed on this forum somewhere.

Here's a link to the part available from Amazon:

You can buy High side valves on eBay for £5.00,, the LP looks like a std tyre valve but uses a different seal, the seals are normally green.

Hi, and thanks for comments, so...

1. Can I screw the valve informed by Jim82 directly to the existing one or do I have to replace the old one with it?
2. For biggriffin's idea I need perhaps some explanation or is the High Pessure valve just the valve Jim82 proposed, hope you can provide a link, this all is new for me...

This I found.

That's the one  :y  Even my mechanic didn't believe you could change just the valve until I showed him the pictures from this forum  ::)

I understand that there is a specific socket for the valve, but I used a 15mm 12 point socket. Make sure you support the 17mm nut on the ally pipe underneath it otherwise you'll shear the whole fitting off. (won't he Jamie  ::))

So, Job Jobbed, installed new pressure side AC valve (actually needed ratchet with 8 corners. Filled again, no leaks and blowing cold air now. We have +3 degrees here now so cold air also in ECO mode..., thanks to OOF for all support.
