Car Forum / Porsche / Porshe 944 / March 2008R12 to R134 AC conversion
Anyone do this with the "easy conversion kit" that I see in the local part's stores? They make it sound easy but what's your real life experience's with these. Murray- '84 944 done it on 4 cars, no problems - add adapters to fittings, add proper oil, fill. But - it is quite common for seal on compressor to go bad with time - suggest changing front seal on compressor first - contact polarbear for the seal and tools to replace, or just send compressor to them for resealing. > Anyone do this with the "easy conversion kit" that I see in the local > part's stores? > They make it sound easy but what's your real life experience's with > these. > > Murray- '84 944  SignaturePosted via a free Usenet account from http://www.teranews.com >done it on 4 cars, no problems - add adapters to fittings, add proper oil, >fill. > >But - it is quite common for seal on compressor to go bad with time - >suggest changing front seal on compressor first - contact polarbear for the >seal and tools to replace, or just send compressor to them for resealing. Thanks for the info. Polar Bear is in FLA and I'm in Idaho so I will try the kit first and see if it leaks (only $35) Cheap enough to try and possibly have to do twice.

It also does not take as much freeze 12 as r12 > Anyone do this with the "easy conversion kit" that I see in the local > part's stores? > They make it sound easy but what's your real life experience's with > these. At a minimum, the entire system should be flushed of old oil, and the receiver/dryer should be replaced. Otherwise you run the risk of serious contamination problems which could eventually lead to more expensive problems. Stay with R12 if at all possible. And yes, it is still available. Even in the PRK (Peoples Republik of Kalifornia.) Walt - '86 944 NA >> Anyone do this with the "easy conversion kit" that I see in the local >> part's stores?

You do NOT need to change the oil, but you need to use a compatible oil, and you do NOT need to change the receiver dryer unless the system has been open for a long time - I've changed 4 cars over, the first one about 6 years ago, no problems with other stuff going bad. The only problems I had were worn out shaft seals, and a couple of bad hoses - particularly on the 85.5, the HP hose to the condenser is prone to rupture to to the specific design - 87 is different, doesn't have the problem - 86 is, if memory serves, the same as 85.5.
