Default How do you depressurize the AC system and drain powersteering.

ok i just started my swap and have a few questions (swap consists of a legacy turbo motor into a 95 impreza)

the power steering needs to be removed to get the motor out. is there a dain for this so taht the system can be disconected and where is it? also do i use the car's powersteering system or the motor thats beeing swapped in's powersteering system.

also on the ac system, whats the best way to get the system depressurised without having it tow'd to a shop and does the system need to be drained in order to be removed or if its just depressurized will it be safe to remove. and how toxic is the freeon charge.

i think thats all for now. tia.

As far as the AC goes, there is good news and bad news.
The Good:
Freon (R12 refrigerent) is not so much toxic as it is dangerous. The freon binds to plain O3 AKA ozone. It destroys our atmosphere. Because of this, the government has a fund in place to pay people for used and contained freon. That means that there are people who are more than willing to come to your house and replace your R12 with the enviromentally safe R134a refrigerant for free.
The Bad:
You don't have freon, you have R134a. They stopped putting freon in cars since 92-93 I believe.
The Ugly:
There isn't anyone who will want to 1. come to your house and 2. do it for free. If you vent it into the air it is a $25,000 dollar fine if caught and it isn't too good for the pollution (It binds to nitrogen and makes it sink ergo it gets real stinky).

As far as the power steering, make sure that the steering wheel is strait and take off one of the lower lines, however, it is built into the crossmember so it might be easier to keep it together and just detach the PS pump and let it dangle.

Good luck, Now go and spred your new found eviromentally consience information to the many plethora of women you are trying to get to know.

Unless of course you were talking about the 92 legacy AC lines. In which case, you might have freon, I doubt it though. Check with Subaru.
