Four seasons ac liquid line help

[86 1/2 Brutus]

I ordered all new ac stuff from Rock auto in May.  Four seasons drop shipped me the hoses.  when they came in, the liquid line does not look right and i called them and they told me they have sold hundreds of these for these trucks.    My evaperator, condenser, compressor, all the other hoses are correct.  the liquid line does not connect to the condenser

pic 1 is the line they sent me
Pic 2 is the old fitting

every liquid line i look up for the truck is the exact same thing as they sent me.  what do i do?

I had the same issue with that line also not fitting.
I got my hoses from Auto Zone on line and they were dropped shipped to me also.
I returned the hose, dryer and belt as they did not fit (see below).

What year is your truck?
What compressor did it come with from the factory?

Mine is an 1981 and came with a York compressor.
I am pretty sure the line I ordered was for an 1984 as I needed the 2 hoses to fit a Sanden compressor of that year.
I also know the later year evap has different fittings for the dryer as the 84 dryer would not fit my 81 evap.
I was lucky that the 2 compressor hoses (for 84 truck) fit to condenser & dryer or I would of had to get ones made.

Hope that helps a little

I went ot autozone, and i dont know how the guy found it, but he did find a hose that looks like the one  i need, he ordered it and is supposed to cme in tomorrow.  we'll see

There is what looks like an adapter where that line hooks up to the condinser, take that out, that is a one way flow valve that you dont need, it's a left over from the 60's

The check valve went between the hose and the condinsor here circled in orange, the check valve is circled in green on the bench.

The hose will thread in in place of the check valve.

Great detail on the 'why and how' that the hose doesn't fit, Steve!

Thanks for sharing! 👍

This is my new hose and old one.  The new one doesn't have the adapter/valve but it fits.



This might answer a question I have:  Since I put my new system in it hisses and gurgles obnoxiously at shut down as it equalizes.  I don't recall the factory system doing this.  Is this because the valve is gone?

Hopefully the one i ordered from autozone will fit, i hope it comes in tomorrow.  it looks like it will.  But my thing is this, i bought a new condenser and hoses, compresser, evap, everything.  when i got the hose i called them and said it did not look right and they assured me it was, and there is no way it can connect without an adaptor.  wish me luck

George, hummer me for a minute, take the check valve out and see if the hose fits the fitting on the condenser.

I can't speak for George but perhaps he doesn't want to give you a hummer.  Anyway, his new hose doesn't have the valve.  Mine doesn't either but the fitting is definitely larger.  Strange...

Not to hijack but your 81 is dealer AC or factory AC?

My 82 is dealer with the York but been a hell of a time trying to find a drier for a '82 as everything is an accumulator.

Great info Steve. Ran into the same confusion with the valve when changing out mine. Glad to know leaving it out was the right choice

When I had my line ordered in there were two options - one for systems with a manual shutoff at the compressor and one without. Mine has the shut off but we went ahead and ordered both in. If I recall correctly there was a difference in thread sizes.

The check valve was to allow the system to be partially opened, same reason for the service valves on the FS-6 compressors and the preceding York/Tecumseh twins. It was indeed a holdover from the days when R12 was dirt cheap and there wasn't a big worry about just dumping some into the air. Interestingly enough, I don't remember my 1963 Jetfire having service valves and I know my 1978 Oldsmobile and 1980 Pontiac didn't have them.

My 81 was factory AC York compressor.
My system did not have a check valve on it and I can tell you the 81 & 84 hose I ordered were different.
IIRC the hose fit the condenser, where it looks this check is, but not the other end.
I don't think the York had service valves but the JY compressor did and I think I ordered hoses for that system.

I've been up all night doing research.  i found yet another catalog mistake.    when i went to autozone yesterday, as luck would have it, there was a guy from a different store.  I brought the hose in and show him what the problem is and we looked it up and surely it gives the same hose.  This guy was alot like I was when i was in parts.  He looked it up for a different truck and sure enough, the hose came up that looks like ours and he ordered it, hopefully it will be in today.   Anyway, i was looking at the slip he gave me, and he look it up for an 88 4.9 with a carburetor.  i look it up on autozone website, and of course it does not give me info on a carb'd 4.9, only efi.  my parts truck is an 88 with a 4.9 eft and the liquid line and evap are different.  anyway.  i start looking, and i look up an 83, and there the hose is, the number the guy found, and it states for NON orifice tube systems and no manual shut off valve at compressor.    Thats wrong.  I check to make sure the condenser is the same and it is.  So this should be the right hose

[old55pete]

Bill, my 73 Buick does not have one ether. Only Ford and Chrysler products used them. Even Chrysler quit using them in the 70's

[86 1/2 Brutus]

yea ford went to the orifice tube in the 80's and the dealer ac was the expansion valve system, but either way.   I hope Rock auto gives me my money back, although i may have trouble as i've had the system for 3 months.  I will call 4 seasons and get them to fix this.

I'm not in parts anymore, but when i was, i found so many catalog errors
So far i found 2

1 on the exhaust manifold flange studs, and now on the liquid line .    
Have to wonder if Gary should start an error thread

[Gary Lewis]

Don't know where to record errors.  Errors in the EVTM's I've handled by correcting the page and placing it back on the site.  But errors in catalogs are another story.  If I have that page posted I could correct it and put it on.

[ArdWrknTrk]

George, I didn't realize you had a life behind the counter.
Explains a lot!

Bill's son Matt once asked me where I worked, when he was with LKQ.
But im just an autistic geek with a mind for numbers.

I think if we tried to document every error, we would have the Manhattan telephone directory (there I go showing my age again!)

[86 1/2 Brutus]

Oh yes Jim, i spent many a year behind that parts counter and my boss and I did not get along at all.  he hated me with a passion and the only reason he kept me around was because of things like this.  But eventually i was able to live the dream and call him on the phone and quote the song " Take this job and shove it"  i used extra language after that.
