I posted a few weeks ago an AC problem on a 94 850 one of my friends owns. The AC doesn't work. He brought it to the dealer to have it checked out. The dealer diagonsis says bad ignition module something or rather which costs $800 parts and $200 labor to fix.

I followed the recommendations in some of the responses I got and tried to charge the system anyway. We found the problem was a leaking receiver. So I asked him to get a receiver. Install it. And then have someone evacuate the system and recharge. Simple enough.

Today, he brought the 850 to my house. We were going to replace the receiver in my driveway. Two threaded connections and we are done. Right? Surprise! The receiver has a flared connection which Volvo does not want car owners to do. It requires some type of special tool I don't even know an Indy would have.

If you look at the receiver in your 850 on the front passenger side you will know what I mean.

So what are our options? Bring it to the stealer?

    These tools are a little tricky to use and there's not a whole lot of room up near the dryer. What you're doing is expanding a circular spring that slips over the flange on one of the tubes. All the spring does is hold the tubes together. The sealing is done by the two o-rings you'll find around the end of the inner tube. You need to push the tool in all the way to expand the spring then hold it in place while you pull back on both the tool and the flanged tube at the same time. I believe you'll also need to disconnect the other ac line from the dryer at the compressor end. This o-ring is a rather special size and I have yet to find one at any auto parts/hardware store. You need to go to a good ac/indy shop or the dealer. Good luck but you may find that it's the hoses or evaporator that's also part of the problem.

    Hello,

    The connections on the accumulator are standard quick-disconnects as used by Ford and others. The tool to remove them is available at most any parts store for $10 (ask for a tool set to remove quick disconnect couplers on Ford fuel systems, for example). There are a few types, some metal and some plastic. I have the $10 plastic set and they work just fine, but the metal set may allow for more leverage on a really stuck coupler (don't know what the metal set sells for, but I know it's a lot more than $10). The tool that I have is shaped like a top hat and slips over the line. There is a spring in there that the tool releases (they work well; I don't know of anything else you may have laying around to try). Anyway, this is easily cured with a visit to the parts store and a cheap tool purchase.

    I hope this helps...

    P.S. - I'll try to ignore that comment you made about the "stealer" :)

      I am skeptical and was tempted to post a picture to show you what it looks like. Couldn't find the tool to insert pictures. But coming from a master tech, I should just keep mouth shut hoping you know exactly what the problem is. I'll try Pepboys next week. Thanks.

      ps: I'll refrain from mentioning the s***ler again if you can find an escape clause for the d**ler who mis-diagnosed my friend's 850 AC problem.

        Hello again,

        I'm not necessarily saying that the accumulator is your problem, but I am sure that the tool I mentioned will remove the pipes from it. Accumulators rarely go bad and very rarely leak (I cannot remember ever seeing one leak). The dessicant inside (drying agent to remove moisture from the system) is really the only part that fails (once it absorbs so much moisture, it cannot hold any more and must be replaced). Even then, the only time that usually happens is when the system is left open for a while. Anyway, if you're positive that the accumulator is your problem, then the tool is what you need (this tool will be needed to replace just about any pipes or components in your 850's A/C system).

        Good Luck, and I hope this helps...

        P.S. - I wasn't necessarily defending ALL dealers, as I have seen some real hack-jobs and bad technicians. Just try not to get a bad opinion of all Volvo dealers. Anyway, I know exactly what you meant...
