ok guys...

i am to the point where the only thing i have holding in my motor is the AC lines and the power steering lines, i think (hope).

the power steering lines, i am assuming i just remove the hose and put a bucket underneath...

but i have never messed with Air Conditioners...if i unbolt the AC pipes will that refrigerant stuff like kill me when it sprays out. what is the proper way to remove them??? or a better question, which way should i remove them without spending money??? i dont have all that recharge and discharge equipment at my disposal...so...any mechanics out there?

also, tell me if this is correct...i have to remove the front tension rods and that support cross beam on both sides and then use a jack to push up on the front cross member...this should allow my motor mounts to slide right out of the frame without hanging up, correct???

hurry up guys, i want to get this out of here today!!! :D

Ok the AC system is a tricky one. I am not suggesting this becuase it can carry a HEFTY EPA fine, and its bad for the environment. But you can remove the shrader valve from the low pressure side of the AC system and let it vent to atmosphere. Dont like that option personally its the whole bad for the environment thing that and the 10000 dollar fine if caught that keeps me from doing it. You could try and get a AC evacuation machine and actually suck down the system, properly, and then you will have it later to recharge your system when done, this will be the most cost affective and safer, smarter and well better way to do this. But most AC evac system tools cost a pretty penny. To give you a example my shop, a Dealership only has 2. If you cant afford this system then call a local shop and see if they can make a "house call" and do it for you.

Honestly though You shouldnt have to drain the system though, you could just unbolt the compressor from the engine and then swing it and the 2 lines connected to it out of the way and then get the engine out. Thats what I helped another tech at my shop do with a Town Car we had to pull the engine on.

thanks hodo...

where is this shrader valve on the low pressure side located on the Z32??? i think i know what your talking about but im not exactly sure...just give me a little where-a-bouts...

if i vent this in the air, should i leave the garage for a few hours to let it clear out or its just bad for like the trees and such.

i was trying to kinda stear clear of removing it and letting it hang because its quite a bit more work...especially on the Z32.

also, was i correct in that last part...i have to push up in the front crossmember to allow the motor mounts to slide through it??? the manual says something like this but its kinda confusing. the manual isnt quite as a detailed as i would have hoped but its still a handy tool to have laying around.

I couldnt tell you where the low pressure side is off the top of my head, and well its windy and cold outside and I REALLY dont feel like going out there and looking. Honestly its probly going to be easier just to unbolt the compressor from the block. Its at the bottom of the engine its not that hard to get to. (But this from a guy who has access to a lift.)
But to give you a idea about the AC system you will have to valve ports on your ac lines, one on one side of your engine, headed to your condensor, and another comming from the AC compressor, the one from the AC condensor is the low pressure side, the it would be VERY cool to the touch when it is operating.

And I dont suggest inhaling the R134 that comes out. So it would be best to keep the place ventilated.

As for the other question couldnt tell you not a clue here.

ok thanks hodo...ill take a look at a later date.

its not that it would be that big of a deal to remove the compressor, its just i was gonna keep the TT motor together so then i would have to unbolt the TT compressor and put mine on. i will see...

what if i just unbolted the pipes straight from the compressor and let it go that way???

you could just do like a friend of m ine did *cough* and just unbolt the lines slowly off the compressor and vent it out like that and get back cause its not good for you as far as it killing you no ....


the proper way and legal way is using a refrigerant recovery unit but how many peolpe have access to it or want to pay the money to have that done...


i been real busy so tomorrow im gonna take out my compressor gunna be a long day as that 4th bolt is a pain and everyone has told me that 4th bolt really sucks...

yeah, i think thats what im gonna do...just unbolt the lines to the compressor really slowly, just let it blow out...

I have my car up in the air right now at work.... Powersteering hose blew this morning, and I took a quick look at the AC compressor, that thing is a BREEZE to get out. twenty minutes tops.

yeah but i have to unbolt from the AC lines anyways...because im just gonna keep the TT AC compressor with the TT motor and then keep the N/A compressor with the N/A motor...you see what i am saying???

I believe they are the same compressor. But hey its your engine. Maybe I am just lazy like that.

:lol:...i will see. the reason i want to keep the N/A with the N/A and the TT with the TT...my N/A has 100k miles on it and the TT engine i bought only has 32k miles on it. which one is more likely to go bad first???

lwell you could also keep it on till it goes and just unbolt it from the engine thoughlike peviusly stated and funny thing is is my cough cough gag did the same thing loland for some reason when i bought my car mine was allready off you know anybody looking for ac components for a z31 let me know lol they all work lol?????? wasnt me

yah just like hodo stated the fine if you were caught is pretty hefty and yes $10,000.. reasong being is because they want to prttect the environment and they are not funded by the government they have to get money from fining shops and pepl but the chances of getting caught by the epa is pretty slim ..

tahst not as bad as if you were caught with a 12lb keg of r-134a or r-12 without your 609 certification penalty carries a 50,000 fine and / or up to 10 yr imprisonment. lol

let us know how it goes

did somebody say keg???

Yea I should probly get my 609...... I keep putting it off but I avoid most AC work becuase I hate dealing with it.
