I finished removing all the A/C components and doing a thorough cleaning and flushing, made some new hoses with barrier hose, and re-installed everything with new o-rings. Then it came time to install the new/rebuilt compressor I picked up from Rock Auto.It didn't fit and I'm not sure why. It seems the compressor is 7/16" longer than the original compressor that came out. The pulley lines up, but the compressor is deeper. The bolt hole spacing (fore to aft) on the original is ~80mm and the new compressor has ~90mm hole spacing. I'm not sure what's going on. That's supposed to be a 10P15C compressor. But it seems something changed along the way. I want to guess that the compressor was revised when the change from R12 to R134a took place. But that's speculation. If any one has some guidance on this, I would appreciate hearing from you.

Note: I know the service port manifolds changed in late 88. My old compressor has the earlier ports that had separate manifolds for suction and discharge (2 pieces).

88 4R, 22RE, A/T-4wd.

 

Not that it helps you a whole lot, but I ordered the UAC kit (UAC KT4738) from Rock Auto, came with compressor and maybe the drier and some o-rings I think, and it fit my 1988 4Runner correctly. Which one did you buy?

 

I bought the 4-Seaons unit w/o the clutch #57310. I'm trying to read the part number from the old compressor. It's a Denso unit of course. But the part number tag is in poor shape. It reads 047200-??? and the rest has faded out.

 

Maybe they sent you the wrong part? I've had it happen. Correct number on box, wrong number on the part. Return it.
The one thing I didn't like is not being able to talk to a real person. Some times the drop down menu doesn't really apply. Took me a while to finally get a return request filled out. I did quickly get another item shipped as soon as I dropped off the wrong one to the UPS store.

 

I don't think it's the wrong part. It seems there are a lot of variations for the body shape and size of the 10P15C compressor. Why they didn't give each their own part number is a mystery. You can tell the longer version from the shorter version by looking at how close the mounting bosses are to the suction/discharge ports. One version of the 10P15C has the bosses right up against the ports and the other has the bosses spaced about 1/4" spacing on each side. (I need the narrow one.)



The Toyota part numbers are assumptions at this point. Depending on where you look, one source says they are interchangeable and another source says they are not. The problem is that I can't find any mounting dimensions for any of the Denso compressor part numbers. For that matter, I haven't been able to find a reliable cross reference for converting the Toyota part number into the Denso part number. It seems the suffix on the 047200-?? listed on the damaged tag was the magic key for identifying which flavor of 10P15C you have. Cripes, I'm not even sure my old unit isn't a 10P13C even though none of Toyota parts manuals list a 10P13C as ever being used in an 88 4runner. What making this even more difficult is that vendors are using generic pictures, so you can't rely on those either to tell what you're getting.

This is driving me nuts. Not my first rodeo tracking down old parts. But I can't say I've ever run across a part that has so many variations and still used the same part number.

 

I'm not aware of any way of making the Denso number useful. When we used to call the Toyota Parts Center with any issue that is the one thing that didn't help them.
But if the numbering system is like Toyota, the numbers before the hyphen will give you the type of part it is, while the numbers after the hyphen will give the specific application.
Example: All Toyota hood part numbers start 53301-xxxxx. Doesn't matter if its a 2000GT or a Landcruiser. The last 5 will tell you which model.
The AC compressor for the RN5/RN6 Trucks and 4Runners were all pretty much the same, iirc. I just replaced my compressor, condensor, expansion valve, and R/D with Denso and had no issues. I would concur with aztoyman. Four seasons stuck the wrong one in the box.

 

I would accept the idea that 4S packaged the wrong item. But that doesn't really explain the pictures clearly showing two different spacings for the bolt holes shown in the pics. I'd order a new compressor from the stealership or parts store and check it on the spot. But that adds another $150 to the cost of the unit.

 

I thought the scenario of the wrong compressor in the box did explain the differences in hole spacing. Many car manufacturers used a 10p15c compressor. Doesn't mean they're interchangeable.
I bought my Denso compressor off Amazon. Free shipping, and didn't need the core shipped back.

 

It's looking like the previous owner did an engine swap from a pickup which used the 10P13C compressor. Grrrr. I wish I had known about that. Would have saved a lot of grief.

 

Old thread but just so nobody else ends up in confusion, the 12240 is a 10pA15c & the 01011 is a 10p15c.They vary significantly in dimensions, all standalone 10p15c compressors without pulleys & manifolds will always line up identical to each other. Cheers

 

Doing this from memory, so take it with a grain of salt -- You can tell the difference between the 10pa15c and the 10p15c very easily because they have different manifolds. The 10pa15c uses a one piece manifold. The mounting holes have the same pattern, but they are offset about a 1/4". (Don't remember if it's to the front or rear.) In any event, I found a bracket but it was for the 10PA15C. So I made an adapter plate to get the pulleys to line up. Been working like a charm ever since.

 

Yes sure, u r right about the manifold on the 10pA15c, I went by your text and the 88320-12240-84 is a toyota part number attached to a 10pA15c type compressor. And that image isn't a 10pA type.
The 88320-01011 is a 10p15c type. You won't find these 2 Toyota part numbers feature together understand one compressor.
What these two images represent is difficult to say. One with 90mm gap could be the 10p17c type. 17 represents the piston volume & is longer compared to the 13 & 15 type (which are understood to be identical in dimensions)

 

The compressor on the left is a 10P13C. The other is the 10P15C. The issue was that the previous owner had swapped motors from a pickup which included the smaller compressor into my 4R.

 

Which establishes that 10p13c & 10p15c are not just different in piston size, dimensions vary, contrary to the misinformation on the web.
I'm in the middle of using a 10p15c on my MR2 (factory fitted 10p13c) and so looking for any data I can get.
Was tempted by the fact that larger pistons will cool cabin faster & the compressor itself will cool down faster.
Thax again, critical input. Journey of compressor to my home is a long one. 🥂
