ac question

[marcos]

my friend just got a 92 honda civic four door and the ac is out of gas
and well on mine I changed it from r 12 to 134
but on my ac hose that I have didn't fit
and I was just wondering if I have to buy the same parts that I used on mine when I changed it from r 12 or is there something else that I need to do with it
any help would be great

and the engine is the b15b7 just if you wan't to know

Whoa, whoa, whoa. Do not be afraid to use words my friend. It took a minute before I understood what you were asking. I never work on my own A/C (too toxic for my tastes, I can live without it), so I asked my dad. But I can say this: If the A/C is dry, then there's a good chance there's a leak in the system. Find the leak before you go ahead and refill the system. Otherwise you will just end up without A/C again.

So aftert talking to my pop for a minute, here's what you are looking at. Some time in the late 80s they changed to a formula of freon that is less toxic. The old stuff is R12, the new is R134. Here's where it gets confusing: The two gases have different boiling points so the compressors and the rest of the system can be very different. How different depends on the engine. So to cover the basics, you will need an A/C compressor that works with the R134, new lines (probably where the leak is), and whatever else I've forgotten. It's not a fun swap and if the system still has any gas in it, then you will have to get it evacuated (its illegal to do it on your own and the gas is very nasty stuff. You don't want to be breathing it in anyway). Unfortunately, most shops refuse to work on A/C that uses R12 because it is so toxic, so good luck on getting the last of the freon out. You can find a newer engine in a junkyard that uses R134 and swap all the parts into the other Civic.

Do you mean a D15B7? I've never heard of a B15. Since all the D-Series are all mostly the same, at least on the block side, then anything newer ought to bolt right in.

yea d 15 haha my bad
and yea there's no leaks from what I can tell and yea it's empty
but the only thing i'm have problems with right now is felling it up
because the hose with the r134 isnt fitting
on the place where the ac is soposed to go in
its to big so my question is
if I need to go and buy the fittings for it

and i'll try to get a picture of it if I can to make it more simple haha

That's probably because the R12 and R134 fittings are different. That would be one of the parts you need to swap out from a newer Civic. Again I don't know exactly what needs to come out the car, but if you swap out everything, then you won't have to worry.

I would not try to put the R134 into an R12 system. I don't know what would go wrong and break, but something will. Just don't try it.

no nothing bad really happens because that what I did to my civic when I first got it
I just went down to autozone and got a r 12 to r 134 kit and it worked just fine
and mine was al ready empty so I had nothing to loose
and the kit comes with a video on how to change from r 12 to r 134 too and its actualy simple

and yea dude we got the fittings for the car today and it worked perfectly ^_^
nice cold air aahhhhhhh haha just kiddin
thanks for the help anyway beaters
