re: VW Technical Bulletin 95-03 - A/C retrofitting

Les, Phill and ALL,
This official bulletin would be worth adding to the file collection, it has useful part and volume references for a/c equipped T3 vans (read vanagon), including it seems they use similar compressors, in particular the Sanden SD 510 and SD 709, both of which Prestige used, so there is that commonality.
 
Goto: http://faculty.ccp.edu/faculty/dreed/Campingart/vanagon/vwretrofit.pdf
 
For compatibility of the genuine VAG bracket, check the compressor mounted on that bracket. Check the distance between the compressor case mounting "ears" or lugs, it should be precisely 83.3mm, as it is for the Prestige bracket. After that, then the correct distance dimension for the twin pulley alignment may have to be checked.
 
See the attached pics and appended dimension.

Well I can see a fault with that a/c.
The belt has fallen off!

Ken,

I just have to ask – what lives in the ice cream container?

mmmmm .... not sure Les. I'd have to go take a look. Even those who know my van don't fully appreciate its potential as an extensive mobile storage/sensory discovery tour. A show & tell could take weeks .. haha

Your air con should be used weekly or it stuffs the compressor and causes leaks. I know of many people who thought that the belt causes a load, so they removed it in winter. Then they reconnected it and no more air con.

There is no load until the air is switched on.

Ken,

For a functioning air conditioner, leaving the belt on is a no-load situation.  For a non-functioning air conditioner, you might as well remove the belt.

Regarding the compressor, the seals need to be kept wet by the refrigerant to prevent them drying and allowing refrigerant to escape past the seals.  Most manufacturers will include an instruction in their owner’s handbook to run the compressor once a week for several minutes to achieve this.  Some manufacturers go a bit further and wire the air conditioner into the reverse gear selection light so that the compressor runs while the vehicle is in reverse.  Since most vehicles will use reverse several times a week, this achieves the desired end of keeping the refrigerant circulating and thus keeping the seals wet.  It follows that this should be done during the winter months, so removing the belt during winter is thoroughly counter-productive.

Compressors can be plagued by another problem called cold leak.  The system will accept gassing up and perform perfectly.  Next morning, it won’t even start because every last molecule of gas has leaked out overnight.  I had this happen with a new Tarago.

Les

Les,
Thanks for that ... very interesting. I can very readily accept that the fundamental issue for those of us who don't use the syncro as a daily/weekly/fortnightly driver is the root cause of ac seal failures, especially in conjunction with a 20yo system & multiple owners.

So I know I'm not alone in this scenario. Mine had no cooling when I bought it, still hasn't, hence my comments.

I take it then, no one deduced that your 2nd sentence is my circumstance?
Cheers.
Ken
