Title: AC overhaul
Post by: Shackeng on 07 July 2013, 19:48:39
Well, I've ordered a new condenser drier, and a refurbed compressor for the 3.2, and as my compressor is not turning, there will be hardly any gas in it, start stripping on Tuesday, other jobs permitting. :y

On the matter of the Compressor, according to the supplier I am responsible for ensuring that the correct amount of PAG150 oil is in it before fitting. Any advice how best to achieve this? Is it as simple as tipping out what's in it, and refilling with the correct amount? :-\ :-\ :-\

Interesting thread Shack, no experience of this so look forward to seeing how you get on. :)

I'm told removing the pump is awkward. :-\

It is! Even more challenging is bolting the pipe work to the top of the compressor with one hand at arm's reach  ???  ;)

I've changed a compressor on a 2.0 petrol,would imagine 2.2 similar,wasn't bad at all from memory :y

Regarding the oil, you'll need to get it charged with the correct amount when the refrigerant is filled. Best to go to someone who knows what they are doing to ensure this is done. I believe certain quantities have to be added a certain points in the system.

New compressors should come charged with oil ???
Title: Re: AC overhaul
Post by: Shackeng on 08 July 2013, 20:23:12

I suppose they should, but the suppliers cover their a**e with this:

Warranty: All condensers now come with a 2 year warranty from date of order, all other parts supplied come with a 12 month warranty. Compressor warranty subject to receiver drier, expansion valve and system flush, failure to do so may invalidate warranty.

YOU MUST CHECK OIL LEVEL IN COMPRESSORS BEFORE INSTALLATION, FAILURE TO DO SO WILL INVALIDATE WARRANTY. COMPRESSORS SUPPLIED DO NOT ALWAYS HAVE CORRECT OIL CHARGE SO IT IS THE INSTALLERS RESPONSIBILITY TO CHECK.

I'll do my best, but not good with the piccies. There is a good one for condenser swap already, so it's the compressor swap that could do with a guide. :y

I would imagine that the compressor is easy on a 2.2?

Though, wasn't your leak condesnor? Thats easy enough - rad out, condensor out, slot new in, pop rad back in.

Just one awkward bolt at rear, half-shrouded by engine mount

I guess I may need some new seals with both condenser and compressor being replaced. Any suggestions?

Replace seals with new ones,very difficult from GM go to a lokal,refrigeration engineers that specialist that do trailers(hgv fridges),the condensor one prob be ok small smear of silcon grease on them,its the coupler seals,but again smear o silicone grease may sort it out,and have you bought a new HP port from gm,

The compressor has dowty washers which will need replacing, the condensor uses O rings (which may well be ok).

You cna remove the compressor with the pipes still attached, easier still with the rad out. Takes a bit of wiggling but you can get it out far anough to allow access to the bolt which secures the plate and dowtys to the top of it.

Done a compressor on the old 1996 2.5 and that was ok but challenging. looked at 2003 2.6. Looks much harder than the old car. Good luck.

Don't think it is compressor, the rad, around the main join to those feed pipes, it chucked out gas there quicker than my ass after a curry.

Keep meaning to get it all fixed  :-[

From previous posts, am I correct in thinking that I will need the car on stands to access the compressor?

Has anyone got the part #'s for the Dowty Seals and 'O' rings please?

Title: Re: AC overhaul
Post by: Shackeng on 09 July 2013, 15:25:10
Apologies if I should have found this elsewhere on OOF, but where exactly do the 'o' rings fit that are associated with the condenser please? Also where exactly are the Dowty seals? Local dealer can't identify either from his pics. :-\

TIA

Got the comp & condenser. The refurbed compressor is a Lucas ACP111, which, as far as I can ascertain, is correct. Can anyone confirm? :-\
