stock 86 GT v6 5sp with A/C and am going to purchase a new compressor
Hello everyone, and thank you for the help in advance. I have searched the forum but can't seem to find a definitive answer.
Which A/C compressor is best for an r134a upgrade HE6 or HE6HE (PO removed it, so no idea what it was). Also, what brands of compressors have been used with good results, ACDELCO, Four Seasons, etc?

Which ever one you choose, resist the temptation to buy a reman unit. Go with a new one. There are design changes that make the new ones 10 times better. The remans are a crap shoot at best, mine lasted less than 50mis and dumped all the oil out. The new one not only seals better but has a lot less draw on the engine.
Thanks "tebailey", Yes, I'm getting a brand new one. Thanks for the info!
In 2013, I bought one from Autozone. It's been the most quiet, freezing cold compressor so far!

That's the same one I have, super quite and ice cold. I had to go back and look at the clutch when I was charging it because I couldn't tell if it was kicking in or not.

Thanks for the info! I just ordered one of these for my '88 GT and used the discount code "TOW20" and got $41 and some change off (came to $192.25 shipped with tax). My AC still works, but the compressor howls like a banshee when it's on. I can't wait to have noise-free air conditioning.

Great, but there's more to achieiving maximum cooling efficiency. Have you also ordered orifice filter, dryer canister, pressure cycling switch, o-ring kit, mineral oil (to lube the orings only), PAG150 oil to dump into canister and compressor?

Nope. I'm just acquiring parts right now. Everything in the AC system will be replaced/renewed when I do the job.

New compressors usually specify PAG46, but always check the instruction sheet that comes with it.

I'm not sure it really matters? I used PAG150 based on back/forth arguments on here and someone quoted a TSB from GM where they recommended PAG150. Probably doesnt matter as long as you use something. And yep, need to flush the old crud. BTW, I thoroughly flushed the condenser AND muffler/hose and didnt have any issues.
GM recommends PAG150 for use in retrofits where the original compressor is used, because the higher viscosity oil works better with the worn out old compressors. The new compressors are manufactured to tighter tolerances, and the manufacturer knows exactly what type of oil should be used with it in order to prevent early failure (more warranty claims = lower revenue).
I used ester oil since it will mix with any mineral oil without ill effects. Almost all the "conversion kits" use ester. So far no problems all is working well.
I've used both ester and PAG for my conversions, honestly have not noticed any difference. They both seem to mix with residual mineral oil.
I would go with the weight of oil specified by the manufacturer though. If they recommend PAG46, use PAG46. I think all Ester oil for refrigeration use is 100 weight.
Thanks everyone for the info. After reading through everything this is the New Compressor I'm leaning toward buying. My question is that the ad states that it is for cars with DA6 or HR6 Compressor. So is this NEW Comprossor a DA6 or HR6 Unit? Something else? Or does it matter? Is this the one others have used?

The notes on their website say 'New with Clutch' so it's new. Usually the new ones are bare metal and the remans are spray painted black
10 cylinder design = improved design over the original DA6 or HR6.
'With DA6 or HR6' means it'll work in either car. For FIeros, it means it will work in all models except 86-88 4 cylinders, which came with the V5 compressor.
My AC still works, but the compressor howls like a banshee when it's on. I can't wait to have noise-free air conditioning.
Yesterday RockinRoger and I had a discussion about this same problem. My 87's compressor does the same thing, sometimes. He said it's because of the clearance in the clutch faces. He said that you can rent the special tool kit containing special bolts and nuts that can adjust the clearance. The clearance, according to him should be precisely .030 inches. This clearance increases over time due to wear. A word of caution from Roger is that you should keep checking the clearance with every small adjustment because if you get it too tight, you must then rent a different tool set to back it out. He said that it can be done in the car.
