You should have cold air at idle regardless, kicking up the rpms will cause the compressor to spin faster and it gets colder.
Start with the basic stuff, make sure the belt isn't slipping on the compressor. If you can get a set of gauges on it watch the high side and make sure the expansion...
Hmm. Maybe a faulty expansion valve that's not opening up all the way? How cold is the line from the compressor to the evaporator? The one on this truck was freezing (as it should be)
Did you clean out all of the lines prior to installing?
Are you using a Denso compressor? Both of the systems I've done have been really cold, much colder than any modern A/C system.
Faulty A/C amplifier causing the compressor to kick on less frequently and for shorter periods of time?
Circling back to this -
Got the proper manifold in and installed - I am now 0/2 on A/C amplifiers during this job, so once again I bypassed it using a cotter pin in pins 3 & 7. The low pressure switch does work, unlike the first time and it held vacuum well.
Got it charged and this thing is...
It was a struggle getting the 4Runner one for my 1987, should've bought three of them back then just to keep handy.
That's the guy we need!
He might have a line on one but if it falls through I'll get in touch with one of ya!
If your 22RE didn't have a compressor bracket mounted, you're going to need to find one from an 80's pickup. I know there were a few different compressors that came on these trucks but both of the 22RE's I've installed A/C on I've used this bracket
It mounts with three M10 X 1.25 X 25 flange...
I guess I had a leg up when I did the A/C install the first time as the 87 did come from the factory with A/C. This made my job easier as the holes were drilled for the evaporator, the A/C bracket was bolted on & Ken left all the VSV/Idle up stuff in place. This 85 has never had A/C, so I'm...
Here's some pics of the shock setup, looks like he had a custom crossmember made up and then custom lower shock mounts. Really nice welds and well done.
It's a really nice truck, original paint too! The bed is currently getting repaired as it had a big dent in it so it'll look even better once I'm done with my AC install.
I'm going to work on getting the evaporator box in tonight so I'll snap some pics of the shock setup. He is running ADS Shocks
Talk about some déjà vu...
Back at it again on my friend's 85. This truck wasn't fitted for A/C like my 87 was so I'll outline any of the additional steps needed here as well. Should be even easier the second time right?
I would recommend buying a new evaporator, condenser, expansion valve, compressor & dryer if possible. The only OEM parts I'd use would be the lines, compressor bracket & the evaporator box obviously. You don't need the amplifier per say, when I did mine I actually just bypassed it by shorting...
I don't think so and wouldn't trust doing that anyways. You could have a A/C shop make a custom line or you could bite the bullet and buy the right manifolds on eBay..I can't believe I even found some for sale...
