Hi all,
Air con now stopped again, after regas a couple weeks ago. I therefore started to supect something more than the HP and LP valves (which have been done :y)
Anyhow, as I had the front grille off (to sort washer bottle sensor) I notice this on the A/C condenser/rad. I assume this is why its now stopped !!
Green A/C Dye leak appears quite noticeable on rhs at the bottom to middle section.
Are they easy to change ? and are there any particular makes / suppliers to go for ? Original GM one ?
I assumed best get new drier at same time ?
What would be cost to get all sorted ?
Thanks in advance.
Andy.

Yep that's leaked out.
Not had to do this job myself so can't help further, but there's plenty of history on here available via the search. Mark Dtm often pops up with a link for condensor and drier.

Normally some on ebay. I think there's a company called coolcars that do them.

Fairly simple job, but requires the rad to come out as well for access. Remember to get new O-rings for the connecting tube blocks. :y

Woo. I never bothered for my rad swap out. :-\ ( not condensor )

Done three and not yet renewed the seals :-\

Sorry, I should have said, you will probably get away without renewing the seals, which do cost a few pence, but if you don't it will only be another job to replace them and the cost of another re-charge. :y

Sorry. I thought we where talking about the atf connecting block to the gear box oil cooler...? :-\

Not changed them either... ::)
Best practice is obviously to change ANY disturbed seal :y but a smidgen of common sense goes a long way :y
-
OK I may give it a go.
Any recommended condensers and driers to get ?
Assume removing main radiator is easy ? And any tips for refilling to make sure no air locks ?
Cheers,
Andy.

Rad has to come out to get it out.
As Shackeng says, worth picking up new seals for the A/C. The old ones *may* be OK, but you won't know for certain until after a £45 regas. So I'd always recommend replacement.
I think chrisgixer is talking about the copper washer seals for the auto gearbox cooler, and these can often be reused without issue, as long as they aren't damaged. If these do weep, its easy enough to change these at any time afterwards, so not really a problem. That said, they can't be expensive, if you wanted to replace them as a matter of course. Your choice :)
Obviously, in addition, you will need coolant, as you'll lose a lot of it when you disconnect the rad. You probably won't lose enough ATF to be overly concerned about, but no harm in picking up a small bottle and checking the level (with engine running) after job is complete. And the regas, obviously.

She is a Manual gearbox 8) so assume ignore the ATF gearbox cooler :y
Yep, wise words on AC seals for the Condenser. Looking, I assume these are two o rings ?
I shall shop about for a Condenser and Drier. Not sure how much they would be at the SDealer ?
Any tip for draining and removing the rad ?
Thanks in advance.
Andy.

Thete is a drain on the rad, pas side.....
Might need to drill the heads off the plastic cover bolts.

Who :o regaseses getting cheaper :)

Just one quick thing that I don't believe has been mentioned. . .
Ensure it's definitely empty by having the shop evacuate it before you open up the system. There could still be refrigerant in there. Then replace condenser and receiver dryer and then take it back for a regas.
As for removing the rad with an auto box I think the fluid lost is so is pretty minimal. I've done a few now and I simply pinch off the lines with needle nosed pliers with a couple pieces of fuel line on to protect hoses. Or I've seen spark plugs shoved in the line to stop drippage. But they may fall out so I prefer the pliers :)

Only used them for the regas the other week.. took them 45min while u wait... Bonnet went up,he played with it for 15min then came to me and said. alls ok and now filling up that took another 30 min and its job done £25 :y
-
Shit-Fit used to do a £25 regas. probably still do. I had mine done 4 times in 6 or 7 months by them, each time it only working for short periods. They were insistent there was a leak, but too slow to detect (the dye is always obvious). So I took it to someone who knew what they were doing, and it worked fine for ages... ...until the compressor self destructed ;D

Yep. They are quite a snug fit though, and getting the thing to sit right with the front fans is a bit of a game - as is getting the main water rad in/out.

I've used these people for Omega radiators, and they have been spot on. They also do condensors - may be worth a look - http://www.carcooling.co.uk/catalog/Vauxhall_Omega_B_94_03-2348-1.html (http://www.carcooling.co.uk/catalog/Vauxhall_Omega_B_94_03-2348-1.html) ;)
