Discharging the Air Cond.

[dhermanesq]

Okay, say that one has to remove the a/c compressor. One disposes of the r-134a the proper way. Then one has to put on a new a/c compressor. Is it then possible to use one of those recharge kits that has the r-134a, the oil, and that neon shit in it to recharge the ENTIRE system? There are a few kits that I've seen 'round these parts that have the gauge set-up. I don't see there being a problem, but you doudes knwo this kind of stuff better than me.

Oh yeah, I drive a EV. That should matter, and it's not funny!!! It simply better suits the family and I. Yo, word to ya moms.




EDIT: Spelling error.

Hey man we don't disrespect the EVs around here, we don't have hangups on water in our engine's either.

It's all good.

As far as I know the kit should recharge the system fine. Be sure to check your ownwer's manual or Bently for proper pressure. It only takes a couple cans. If the pressure is too high it will continually kick the compressor off to soon, and possibly blow your expansion valve into pieces.

I don't know this from first hand experience with a MK3 Jetta, I just got it as "word on the street".

Whenever you have the system open, it's best to get it evacuated. This assures that as much water vapor and air is removed from the system as possible before introducing the fresh refrigerant, so that what is in therewhen you're done is only what is supposed to be in there. Once it's pulled down, the normal procedure is to wait an hour and see that it holds vacuum, because this is the ideal time to make any other epairs, such as seals, fittings or hoses that might be leaking. Then you can refill it with the reasonable assurance that it will hold onto that new fluid and not need service for awhile.

Also, if the receiver/dryer wasn't replaced when the system was originally switched to R134, now is a good time to replace that as well. It's normally done with the switch, but not everyone does it.

Rawsome, thanks for all the answers. The a/c system is stock r-134a. I shouldn't have to change anything I hope, if there is a leak in it somewhere, I'm going to get it fixed. Like I said, there is no way I wouldn't have it not working because none of the rear windows open. That would suck for the baby, the dog and, in the way way back, the mother-in-law, who smokes like a fucking chimney, and doesn't need to be ridin' with me anyhow! In that case, I would open my window, turn on the rear heater, and hopefully, she'll never ever wanna ride in the van again!! Sound like a plan? I'm willing to try anything with her.

Bessssssst,
