freon system
 

Has anybody had any bad experiences with the stock freon compressor. Mine just went south ( siezed ) should i buy a porsche replacement part or aftermarket. Does anybody have one for sale. 87' 944S

The compressors are prone to leaking. If you can, I recommend a good rotary aftermarket compressor. Do some shopping around, you should find a good one at a comparable price to a stock compressor.

hi i do alot of a/c work and what you need to know is that there are only a few companys that make compressors around the world..... maybe 3.... i don't think theres an aftermarket . ,, unless you mean rebuilt???? find a local dealer/installer. if the guy tells you one brand is better than another walk away.... its either "new" or "rebuilt"...... plus its the installer that makes it the thing work.......find a good a/c installer and you should be happy with the price you pay.......i found a kid whos been working on porsche cars since he was 17.....hes 35 now.......he was weened on porsche.... hes good

My bad for poor word usage.

By "aftermarket" I meant "Not Porsche" or more specifically "Not Nippondenso" (however you spell it)

coincidence; today i had the freon (r12) in my bmw recharged...cost for 2 pounds freon, not including labor: $100! ouch! the new refridgerant used in newer cars is 1/3 cheaper, but doesn't cool quite as well i'm told.

Just read on Rennlist about a place called Griffiths Check it out. The guy said he was quoted $600 for a Keuhl compressor. Another person mentioned Vertex. Good luck.

Thanks for all your help, it summer and like to be comfortable while driving around. Just an addition note is some of the aftermarket compressors require you to modify the brackets- correct?? and possibly the compressor mounting ears???

I found the tolerences on my compressor ears to be extremely tight. Someone else that removed the compressor took several days, on and off, to get it back in, eventually requiring a tranny jack to force it back in after tryin all kinds of heating/cooling of metal solutions. Some patience might be needed if you're doing this yourself then use a shop only to vacuum and charge the system. Some of the conversions have adapter brackets, some do not.

As far as which compressor, I think alot of that depends on who is going to service your car in the future. If you have to use any old shop to recharge and do A/C work, then you might want to convert over to R134A now to save money over time. I have a shop that doesn't charge an arm and a leg for R12, so I choose to keep with the older freon, I'll take all the cooling power I can get in Florida. www.************************ has rebuilt compressors for $225 IF your core is rebuildable, you say it's seized... it might not be rebuildable. Tweeks, www.madirest.com , I think has the best deal on a conversion kit, $600 includes dryer, a couple new hoses and a new belt... no core charge and it can work with either R12 or R134A. You might want to check out www.**********.com like someone else mentioned. They have a Sanden conversion for only $389. I don't know anything about the conversion and what it includes... but that price isn't bad eh?

Our shop, I think, $80 for a pound of R12. The reason you pay an arm and a leg for it is because we pay an arm and a leg for it. It is getting harder and harder to find as well. The cheapest we could find it for was just under a grand.

This guy was smart and invested before the price went up, and he likes me... most get charged regular rates like most others are charging. He's a sailing friend also, he had just sold a nice boat he had and plunked down a chunk of his procedes in R12.

my '86 was converted over to R134a and the PO spent about $1500 bucks to do it. I think it was kind of a rip-off because it looked like the original compressor, maybe a new dryer and a couple of hoses -- that's it. It cools plenty and I'm in TX were it is HOT. I heard the the older 944's had some capacity problems so they over compensated on the 85 1/2 and newer ones
