Went to get the aircon vacuumed out and filled up.
Its had a little leak for a while but this time I decided to ask him to get the UV light out.

Okay, i've got spots of dye on the condenser and also the pressure switch on the pump.

How much and from where is the best place to get a condenser from ?

Also is the pump pressure switch fixable of do I have to replace the pump ?

TIA

[tunnie]

this company was recommended for me:

https://www.carcooling.co.uk

Never bothered buying from them in the the end, I had a distinct case of CBA and took it to my local Vauxhall specialist. Just told them to fit a new condenser and get the aircon working.

There isn't a pressure switch on the compressor, the only electrical connection is to the clutch coil. You can get some slight leak from the dowty washers on the compressor (it may be this that's showing)

Thanks for the link Tunnie 

97 quid delivered isn't too bad I suppose 

The next question is .............

Can the seal on the pressure be replaced ?


Iirc, Broocie did all his seals a few years ago 
I'll have a dig around the forum later when I get time

As always, I'll bow to your greater knowledge on these things 

Is said dowty washers readily available ?

I purchased a pack of various rubber seals a while ago so if i'm going to do the job, best sort everything out together 

[frostbite]

Probably nitryl washers  as its resistant to pretty much anything

where cheap rubber would dissolve when it touches oils corrosive gas

GM part code is:

52455752 (being yank they are a 5/8 dowty type seal) - 2 off

Should be available pretty much anywhere, Dowty type seals are usually Nitrile as they are a high pressure seal designed for hydraulics

[Marks DTM Calib]

I should add, for completeness, the pressure switches are in the metal hoses (high and low pressure switches in high and low pressure lines)

Well going away for 2 weeks ish from Monday so it will have to wait 

Thanks lads for all the info and I will have a play when I get back

Which clearly they oppsed up quite badly

Well that was 18 months go, so probably a small leak somewhere else.

Which if they've dyed it the first time, the leak will be easily identified now

[tunnie]

How do you know you they did not dye it? 

There was dye in the system, bright green stuff around the cap of the HP valve. But as well all know the dye is utterly useless in actually diagnosing a leak, as always on the Omega the compressor is covered in crap and dye, the old 3.0 estate had green dye all over the place, yet the air-con never failed.

Recall your MV6 needing a yearly re-gas, I suspect this will be the same.

[Kevin Wood]

Bright green stuff might well be oil.

[tigers_gonads]

At the end of the day, all omegas are getting long in the tooth now and will have tiny leaks pretty much everywhere 

We can either put up with paying 40 quid ish a year and hope it gets us through the summer OR replace all the seals then if its still leaking, look more closely at the larger components.

If dye was used - and the dye can generally only be seen properly with UV, but some are a fluorescent yellow now - then any leak would be obvious (under UV light if its UV dye).  That's how I know they didn't put dye in it, or otherwise stringing you along


The MV6 needed almost monthly regases purely because the national fast fit people don't know what they are doing.  Look it to somebody who did, and low and behold, no further issues, despite nothing being replaced other than the refrig.

If the car was new to me, I'd do that, but ensure there was dye in it.  Then when it stopped working (if it didn't last 2 or 3 years), I'd resolve the leaks that would now be visible, and make a sensible decision on next steps

But then you seem to come on here saying what a PoS your 3.2 is because the A/C only lasted a year, whereas its really because you are just happy to bodge/pray  .  Not that I have an issue with that, its your motor to do with as you wish, and you might be quite happy to continually fix the symptom, not the cause. But you don't sound it

Interesting. I had mine regased twice last summer by ats, lost it all by September. Just had it regased by Mr Clutch, seems better than last year already. Only two weeks in, I will have too see if it lasts all summer. If it doesn’t, might take the advice of replacing the low and high ports😀

Is this what I need to replace the low and high port?
