Car Forum / Volvo Cars / June 200599 S70 airconditioner recharge
My a/c is not cold and I would like to recharge it. I thought this would be a simple procedure because everyone does it but I am learning that is not true with a Volvo. I went to several local auto part stores and no one knows how to recharge the a/c on my volvo. I am being told I have to take it to the dealer. I understand that there is a high and low side and you recharge by the low side. However, no can seem to find a low side on my volvo and I have even asked several friends who are mechanics. If I have to take it to the dealer then I will, but before I do that I want to make sure that I can't do it on my own. Any help would be greatly appreciated.

And there is only a low side valve, the high pressure can only be read via a scan tool. And while often the systems are low on refrigerant, the only way to make sure the system is properly charged is to evacuate it completely and install a weighed amount.  SignatureMike F.

Thanks for all the info, this is what I thought but wanted to get a second opinion. >>>My a/c is not cold and I would like to recharge it.

OK, I can see the filler valve, so how do you evacuate the system, and how much are you supposed to put in? J. >> And the cap over the filler valve has "Max 8 Nm" on it.

You fill in between 750-850 grams of R134, the exact amount can be seen on a sticker on the right fender. You need a special vacuum pump to evacuate the system and afterwards to fill in the right amount, only a workshop has that.

[quoted text clipped - 5 lines] > > Niels The exact amount is indicated on a sticker somewhere under the hood. (On my '98 S and V70s, the amount is 750 grams.) Often folks just buy the diy cans from auto parts stores and add one to whatever is remaining. If the air is still not cold, and the a/c clutch is still cycling quickly they add another.

Thanks for all the help, I got mine filled and the air is cold again. It was very easy. Becky Hi, I'm not a mechanic but have had a cold a/c also. Happily durin warranty period. A/c circuit is under very high pressure and can onl be filled and pressurized by Volvo workshop or any specialized a/ workshop. They take care of not leaking dangerous fluids/gasses an check the system for leaking. Just filling/pressurizing should cos that much but beware when the circuit would leak.

I see a long silver fin mounted on top of the manifold with a blue cap on the right side (looking at the motor); would this be the fill cap?

Other posts in this thread describe the appearance and location of the A/C port. SignatureMike F. Thornhill (near Toronto), Ont.
