The Ultimate A/C Thread For Pigs! (Air Conditioning)

[PabloCruise]

The idle speed control valve should open up a bit under the compressor load and at least try to keep the engine idling around 650rpm.

FJ62 and FJ80s didn’t cut the a/c off when at idle. The ecu has the ISCV compensate for the load and attempt to keep the idle speed at 650rpm.

I don’t think your ISCV is working properly...

The A/c on signal to ecu from amplifier just raises the desired idle speed to make the a/c system more efficient and blow colder. Compressor spins faster, and fan moves more air over condenser.

Thank you! That helps confirm my suspicions.

Looking forward to your product!

I have a solution for integrating factory a/c to an efi motor; to get rid of the idle speed cutoff function.

Perfect for a piggie with a diesel, or an efi motor that can control idle speed when a/c is on.

It works without any coil input(rpm) but still allows stock thermistor and temp dial to set temp.

More info to follow. Going to build a few for sale, so I will need to get a star. Will include controller box and a small wiring adapter, with or without a wire to integrate to ecu “a/c on signal”

Definitely works with 73 and later systems, but I am going to create a slightly different harness adapter for the 70-73 style.

If you come up with a stock underdash unit, without wiring or controller I can also get you functional with this and a new harness.

Did this used to be a separate thread?

Any updates on this?

Thanks!

Found a cool AC resource, hoping they have a condensor for me that will not require cutting of the radiator cross-member:

Are bulkhead fittings an option?

That's what I use for my heat and A/C lines.

Would one of you 55 guys like to own a very good condition A/C manual of your very own? 60 bucks plus shipping.

They are $19.99 plus shipping from SOR. Just FYI.

That’s nice. Mine is not a copy.

I thought I had posted a link in here for hose ends that will allow custom hoses to bolt up to Denso compressor manifolds.

Does anyone know where to get these?

Wonder if these would work?

Cold Hose - Denso 10S17F 10S20F Compressor Adapters

GM Nippondenso (Denso) 10S17F & 10S20F (Sealing Washer) compressor adapters used to convert a stock compressor to aftermarket hoses. The adapters are standard #8 discharge and #10 suction fittings. The discharge fitting has standard 3/4"-16 and the sucti

Wonder if these would work?

I would also like to know if they work. I hunted for weeks for metric hose parts and came up dry.

When my hoses failed and the mechanic said American hoses would not swedge correctly. I had a machinist cut off the hose side of the fittings and weld on American swedge ends. When the machinist was done one could not tell it had been done.

This is a great post , Thank you PabloCruise for your post all the information I needed. With that said Iam going to push the golden buzzer button. TTT

Glad I could help!
Maybe we could get the mods to merge the two threads and sticky...

I guess I have not been keeping this thread up very well.

I have some good details about my AC progress (or lack thereof) around here:|

Here is where I measured the opening (wait, what?) to see how big of a condenser I could fit:

Everyone needs a chance to see @Spook50 rebuild a Denso 10P15C AC compressor:

FJ62 A/C overhaul with Denso 10P15C compressor rebuild

I figured I would do a writeup of my overhaul of my 62's A/C for those who are able and willing to do their own. I'm not converting to R-134A since I have R12 still available and will be charging with that when I have it all back together. What I'm doing is replacing my evaporator, pressure...

Found this link for the AC Service Manual a couple of days ago. Thought I would add it to the thread.
