parts list for a new a/c system? (1 Viewer)

[dozerking]

so here are a few pics of what i have this is going in a 84 fj60 with a 93 tbi 350! i got a condensor out of a 94 4runner which you see in the pic. what i want to happen is fab everything up have it all in the rig have all the parts ill need and take it to a a/c shop and have them put it together there are not alot of landcrusers around my part of the country so i know ill have to wait on any parts and that means down time! so here are my questions and thanks for the help!



1 with the parts that i have am i missing anything?


2 i know ill need custom hoses where is a good place to find the end that ill need?


3 when i got my cruiser the last guy had torn out all the a/c stuff all that was left is the switch in the dash and the conectors at the firewall so what else is there that i might need?


4 anything else im missing?

why not use toyota parts....that fit the truck off a junk 60 (condensor, some of the hoses etc) get new toyota dryer. Use new GM compressor, get new GM hose that mates to GM compressor, then has shop put the ends on the hose that will allow you to mate with the toyota parts. Some auto parts shops build hyrdaulic hose and have the ability to make custom hoses.

I doubt you will find an A/C shop that will mix and match and install all of that (but if you do and they know what they are doing then that would be a plus).

Why not call the guys at coolstream to get their advice and get parts from him? He has posted on the board a number of times.

I have a 5.7 vortec. Compressor is GM, hose that connects to compressor is a gm hoses with the other ends changed to mate with the evaporator core and teh condensor. All other parts are toyota (OEM to the FJ60), new dryer.

You should never run a used dryer/accumulator...always run new. Any used A/C compressor should be assumed to be non-functional.

You will have to make sure your parts will physically work on your truck if you decide to go with teh parts from the various other vehicles.

Is the evaporator box still in place under the passenger side dash? If so, this is relatively easy to put together. If not, you'll need to source a used evaporator box from someone parting one. The R4 compressor is very common, so you can use a manifold like what's pictured below to attach the hoses to the compressor. You'll also need to build a small diameter hose from the bottom of the condenser to the drier, then from the drier to the fitting on the firewall. Will the larger of those two condensers fit? The system might cool better with it. Will you be using R12 or R134a? If R12 use A/C specific mineral oil in the system, if R134a use PAG 150, those compressors won't live on anything else. Sorry to have answered your questions with more questiions.

elbert trying to find any landcruiser parts in north idaho is like meeting a playmate down at the local pub on a monday morning lol i have called every junk yard within a 200 mile radius and not one has a landcruser of any type in it!! the 4 runner is a pretty nice fit and is in great shape plus i love to fab new things so making mounts this weekend will give me something to do! the a/c blew cold in the truck that i took it out of so i dont think ill need a new compressor!

Its fine to answer a question with a question i do it whenever my girlfriend is mad at me lol sooooo yes the evaporator box is and hookups are still under the dash and in the firewall that and the button to turn the a/c on were all that i ended up with when i bought the rig! the biggest condensor will fit but it is about 6 inches bigger on each side of my radiator and its kind of beat up the 4 runner one(the smaller of the two) is a pretty nice fit! the chevy is r12 and im pretty sure the 1994 4 runner is 134 so ill have to clean both systems and then use the right oil?? do you sell all the fittings for everything i need to do here???


thanks for the help!!

yea...but they have as area on the board for people selling used parts and parting vehicles out for parts. Same issue around where I live...regarding LC parts. I was lucky my 60 had all the ac stuff on it when it was stock, but I've bought a new dryer and various used hoses to get spare ends.

If you can get your condensor mounted good in front of the radiator and not obstruct your access ports then you can make the other parts work....assume you will run GM compressor. Do invest in a new dryer and you might want to talk to the A/C shop you plan to use before you get to far into the project to make sure you are on he right track.

Having just done all this over the past couple months, if I were doing it again the only used parts I would use are the A/C button on the dash, the evaporator, and all the nuts / bolts / grommets, etc.

Pull out your evaporator box from under the dash and clean out all the junk that's accumulated throughout the years. I had an A/C shop flush mine for about $20. When reinstalling it, replace all the foam seals to make sure you get the most airflow possible.

Get the biggest parallel flow condenser that will fit. I used a 16" x 26" (CN 21007), cost around $120. It fits perfectly using the factory hardware.

The hoses and fittings are kind of a pain. The small fitting on the evaporator is a size that the A/C shops near me weren't familiar with. All the other fittings were standard. You can pretty easily find them mail order, but you'll need to find a place to crimp them too. Places around here are charging $5 a crimp. I've heard that the Parker stores will crimp them for free if you buy the hose and fittings from them but I can't confirm it.

Definitely get a new dryer.

so where did you get your condensor from? ill be sure to pull the box apart and clean it!! so how did you wire up the chevy parts? im still unsure on which wire was the one for my old a/c???

langsen, a question on the condenser. Is it for R134a? I've read somewhere that some of the newer replacement condensers are designed for R134a vs R12. Meaning, there is better cooling in the 134 condenser, so more fins and better thermal dissipation. I know for most applications it won't matter, but for the anally retentive (and those living in +100 degree temps), we need to know!

Isn't the small fitting on the evaporator a size #6?

Newer condensers are a parallel-flow design, much like a radiator. Older designs such as tube and fin or serpentine are less efficient, so don't work as well with R134a. All new cars use the parallel-flow design.

I think the evaporator fitting is 5/16" not the more normal #6.

When I did mine I went and picked up a "universal" ac line kit from vintage air

Then got a new condenser from coolstream. Make the hoses up and call it good. All things considered it was a lot easier than I expected.

I had a dealer installed AC in the FJ60 we bought, we took it out and I called Proffitt's Cruisers and had them send me a box full of everything I needed to make my AC stock. I can't remember the exact price but it was WAY cheaper than ordering from Toyota or SOR, now the truck blows very cold, even for summer in Texas... my daughter is always asking me to turn the AC down.
