Hello All,

I am at my wits end and thought I would turn to the professionals. I am putting A/C in my 1995 toyota 2.4l DLX 2wd pickup. I sourced the difficult to get HVAC box off of Ebay. The seller assured me it came out of a 1995 toyota pickup 22re. I replaced the evaporator core with and expansion valve. The box fit like a glove under the dash. However when I went to connect the suction hose the fitting was too small. Fast forward past three different A/C suction hoses none of which fit I decided to try a 3.0L hose just to see if it would work. The fitting was a perfect for the evaporator core but the hose wasn't long enough and the fitting for the compressor fit but the bend in the metal part rubs the compressor pulley. At this point I am at a loss. The best I can come up with is this diagram:


Does anyone know where to find the suction amd discharge lines? Or can you explain why lines for a 2.4l that I can get off of partsgeek won't fit my evaporator core or compressor?

Did Toyota use a 3.0l evaporator core in 2.4l trucks and make a hose that was specific to that design?

Any help or atleast explanation will be greatly appreciated.

 

Use the fitting that fit but cut the aluminum crimped sleeve off and remove the hose. You can have new hose cut to length and crimped on. Or you can buy new hose ends that fit and have new hoses made. Any auto A/C shop should be able to help you out. I hooked up my 3.4 V6 compressor to my 1988 22RE system this way.

The hardest item to find is the 8mm Toyota specific hard lines. There are no generic substitutions out there that I know of anyway. I have straightened out the hard line and re-bent it as needed for my 3.4 swap.

 

You can also have hoses made with charge ports in the hose if needed. My 3.4 compressor didn't have charge ports like the 22RE compressor did so this is what I did.

 

I purchased the hard lines from the Dealer so I am good there. These soft lines are just impossible to find. Thanks for the help though. Now I need to hunt up all the fittings!

 

I have ordered the fittings online when I knew exactly what I needed. I also go to a local A/C repair shop so I can see all the weird fittings I never knew were available. The owner sold me the fittings and a length of hose slightly longer than what I estimated that I needed for each hose. I went back home and installed the fittings on the connection at both ends at the best angle, then cut the hose to length and slid it on the fittings. I marked how they are "clocked" so I could take it back to the shop and have them crimped. If they are straight fittings or a straight fitting on one end, no need to clock the angled fitting.

It's kind of a pain to make multiple trips to get a hose made but it sucks when it's made wrong.

I don't make enough hoses to buy a crimper but the tools are out there if you decide to make your own. I have also used Aeroquip reusable hose ends on some projects but those are pricey.

Good luck with your project.

 

Ive been battling the a/c line thing for a bit too on my engine swap. Bought 3 different lines and they either didnt fit the compressor manifold or were made incorrectly and backwards. Took the broken oem hose to the only shop in my area and was told "i don't work on that import crap". I walked out and got into my car that was the only one in the parking lot and left.
I found fittings on Amazon that looked like they could work with the manifold if I made new custom hoses but havent gotten there yet. Hopefully this summer I am able to get to it.

 

If you have no luck finding the fittings you need, check centuryautoair.com IDK if they sell online but maybe? They can at least tell you what you need.

I've used this business in Tucson, AZ for years. Family business, knows their stuff and super helpful. A bit confusing when you look up Century Air. It also comes up as Tubes and Hoses. I think he split the hydraulic side off to his son. They make hydraulic hoses and even power steering and brake lines and hoses. Awesome quality and customer service. Same building and address on Grant road in Tucson. I have no affiliation with them other than being a satisfied customer for years.

Good luck with your project.

 

Sounds like perhaps the confusion comes from some of these '89-'95 pickups having metric A/C fittings at the evaporator (and possibly other parts of the system) and others having standard fittings. I don't know what dictates which thread type came on any given Toyota pickup (would love to know though... "Dealer option" A/C vs "maker option" A/C maybe??), but it's seemingly un-intuitive.

Case in point -- I just purchased a replacement evaporator for my '94 pickup (4x4, XtraCab, 22RE, federal emissions, 9/1993 production date).

On RockAuto right now, there's 5 evaporators to choose from:
-- 2 say "standard fittings"
-- 1 says "metric fittings"
-- the last 2 don't say anything

Given that my truck was made in Japan (VIN starts with "J" rather than "4" for US-made pickups), I would've guessed I'd need metric fittings.
Fortunately, I carefully checked the threads before ordering because, for whatever reason, my truck uses standard fittings.

Furthermore, if you use PartSouq or Amayama to look up a 1994 pickup pickup like mine, it'll give 2 different part numbers for the evaporator (A/C stuff is in the electrical section on all these OEM parts diagram websites).
Then if you use my truck's VIN to on the same website, it'll get more specific by only listing 1 of those 2 part numbers. Presumably this part number is specific to the standard, non-metric evaporator, but I couldn't find confirmation on this as the specs don't seem to be listed anywhere and the OEM/Denso evaporators are discontinued.
And if you take that 1 part number to RockAuto and search for it, it returns all 5 of the evaporators that they currently sell, which doesn't help.

And for the record, in case anybody finds themselves here after googling to try to make sense of the confusion -- The 88501-89111 evaporator specified specifically for my pickup uses standard fittings, not metric.

 

Whatever you do, when connecting to your manifold just be real careful not to tighten the hose up wrong and mess up the manifold. You won't find one for sale anywhere that I can find. For your hoses, if you have a good ac guy take the hose or the vehicle to him and he'll get the right fitting and fix it up. If not, check this link out. They have good pics of all the hose end connections made probably. https://coldhose.com/collections/fittings. Great resource.
And if you need help determining the thread of a fitting, Amazon sells a kit that you can use to identify threads. Not sure they have one as big as the threads on the evaporator though. But home depot and Lowe's usually do in the plumbing department. I went through the same problems when I replaced my air conditioner years ago. I finally gave up and called the shop to see if they could help and they took care of whatever fitting was required to get the evaporator connected. I feel your pain
