Re: [MBZ] AC Leak

Replaced a bunch of O-rings yesterday, everything I could get to without a major undertaking. Still leaked down to around 20"-25” Hg after 30-45 minutes. I replaced the receiver dryer, charged the system with R134a and used the Cliplight sealer that saved the 500 evaporator. 24 hours later

Re: [MBZ] AC Leak

You can find complete sets for a specific application for around $15.00 or less. You can also buy the individual O rings, but I figure it can’t hurt to have the whole set. About the only thing you might not need is the big seal/O ring for the manifold on the compressor if one is used. Dan

Thanks a bunch for the offer, Mitch, but I ordered a complete set for the whole system just to have them. I could have gone up to my local Advance Auto, as they have all kinds of A O rings and probably have the correct size, but I figure I’ll get a complete set just to have on hand and for

Re: [MBZ] AC Leak

If you know what size the two compressor to manifold rings are I can probably mail them to you in the morning, if green rubber O-rings are what you need. I bought a universal Four Seasons R134 ring kit this summer and ended up using none of them. I was replacing a compressor and liked the steel

[MBZ] AC Leak

Got my leak detector the other day, just went out and put enough refrigerant in to get 50 psi on both sides of the system as they suggested. Definitely got a hit at the connection on the back of the compressor where the pipes bolt up to the compressor case. Ordering a set of O rings today.

Re: [MBZ] AC Leak

How tough is it to get to? Based on my knowledge I'm assuming it's next to the evaporator? Thanks, Dan On Sep 21, 2014, at 11:52 PM, Peter Frederick psf...@earthlink.net wrote: Stuck or plugged expansion valve. Probably not as much a leak as no circulation. Peter

Meh. It's going to a trusted indie this afternoon. I don't really care to do AC work, and this way it's done right without screwing anything up in the process. The first time in probably 4-5 years I've had to defer to an outside mechanic, so I can't complain. The important thing is to know

Drop some UV dye in it, or an oil recharge with some in it. If it's the evaporator, you'll (eventually) see it around the condensate drains. Regardless, you'll have a good idea of where to look. I wouldn't be surprised to find a leaky service valve, especially the high side one. -j. -- John

Re: [MBZ] AC Leak

Here's what it was doing this morning, with an ambient in the low 80s: Low side was at or near zero, high side was around 150. I put about half a can in the system and got bubbles, but it was cooling slightly. Low side barely came up, but high side remained at 150. I left it at that, as I'm

Re: [MBZ] AC Leak

I would add that this is a native R-134a system, not a conversion. Also, low side pressures did come up to the 30s when I added refrigerant, but dropped when I closed the service valve to the can. I would assume this is due to the low charge? Dan On Sep 21, 2014, at 9:36 AM, Peter Frederick

That is a problem, maybe THE problem... Bubbling oil? I'd add an ounce or two of oil to replace what may have been lost. Max Dillon, Charleston SC On Sep 21, 2014 1:37 PM, Dan Penoff via Mercedes mercedes@okiebenz.com wrote: Interesting enough, I did notice that the low side service valve
