Default 02 wrx - removing ac compressor

It looks like there is one bolt that I can't get to without removing the intake manifold. I'd rather not remove the intake at this point. Does anyone have any tips?

Long extension and a universal joint or a wobble socket. I know exactly what you're talking about, PITA! Be patient.

I took my ac out pretty easily. You need some extenders for your tools, and patience helps. Good luck

Ok here's another newbish question.

I should have removed the crankshaft pulley before I pulled the engine, but I didn't. DOH.

Now I'm having trouble removing it. It IS a counterclockwise turn to remove it right? Any other tips on keeping the engine from turning over?

I need to get my AC compressor out too... I looked at the tricky bolts a few weeks ago, and decided not to tackle it that day. Those 4 bolts are so long, it doesn't look like the one in the back can even slide out all the way?

A 1/2" impact takes that right off like you wouldn't believe

It's kind of a cluster**** but get them all loose and they come out with the compressor, if that makes sense.

Hmmm, right now it doesn't, but its nice outside and I'm going to leave work early, and this thread has gotten me in the mood to tackle this again. I just remember getting 2 or 3 of them out, but the last one was like wtf... they're like 4 or 5 inches long and it looked it like would hit something (timing belt cover, or dipstick tube, or something... can't remember).

Is it just the 4 horizontal bolts, and thats it? (obviously the AC lines and all that are off). It seems like there was something going vertical down onto the block or something.

It's been a while since I've pulled one but I'm pretty sure you have to remove the dipstick... 1 bolt and then just pull on it. You'll see when you get in there.

That back bolt is a biatch but some wobble sockets and an extension does the trick.

Did you have the r134a recoverd if not id suggest doing it for the earths sake since r134a is bad for the atmo. and after you do that and dismantle everything keep it all in baggys and make sure they dont get any water in them or they will rust really bad.

^^ Not as bad as R-12 but still not good. Some shops might actually pay you for 134a though, so it's a bad financial proposition to vent money into the atmosphere lol

That is true its not as bad but it still makes its own layer of crud right under the r12 crud so no matter what its still bad

Got it off, what a pain. (I didn't have to worry about the r134a, it all leaked out long long ago, my AC hasn't worked for over a year, and it hasn't bothered me, thats why I took it out)

Anybody ever get a CEL when removing the AC?

I got it all out, then just moved the car to the backyard, and the CEL came on (didn't even drive it on the street). The only thing I touched was the AC, so I'm hoping its that. I haven't pulled the code yet.

Well I give up. If a 400lb impact wrench won't do it, then I think it's time to take it to a pro.

I think I'll take the long block in to a shop and have them pull of this stupid thing.

There is a special tool that will hold the pulley in place while you tighten/loosen the main crank pulley. I do not have one, but maybe someone on here can let you borrow one...

Holy hell, is it just spinning the motor or what?

I took mine off today, used a shorty breaker bar with a piece of pipe on it. It wasn't easy but it came off.

I can only guess that it must be spinning the motor just slightly to absorb the impact wrench. If I had the Subaru tool I guess I'd just use a breaker bar.

I did try the breaker bar approach with a long bolt in one of the flywheel mounting holes, but that just bent the bolt.

Yeah, taking that one to the professionals (who are insured, in case it breaks) sounds like a good call.

I work for a air conditioning shop in kent...

no one will pay you for R134a. but i will recover it for free.
especially in light of the fact that flouracarbon HFC134a has a half life of 11-12 years in the atmosphere... and when mixed with moisture in a open enviorment it turns into a gaseous form of hydraflouric acid that can affect bone marrow and in general isn't very pleasant. '

in retrospect though. R12 stays in the atmosphere 175 years of half life, and turns into phosgene gas (AKA mustard Gas) when it hits its flash temp of 700 degrees. So none of you vent it to the atmosphere.

if you come by my shop at 26922 132nd ave se Kent 98042 i will recover it for free before engine swaps. Probabaly hook you up with a discount on a recharge when/if you want AC again too.

O also, venting and or servicing of refrigerant by a individual that does not have a permit is punishable by the department of ecology citation often in excess too 25,000$

I figured I would toss in my answer to op's question also for others like me that searched how to pull the compressor. The three bolts closest to you are cake. The last as stated before is a pita. What I found works best is simple... A 8in quater inch drive swivel extension with a quarter inch ratchet and quarter inch 14mm socket will get the job done in a hurry.


Good luck.
