99 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.

Thanks,

Becky

The filling point is placed on a pipe between the power steering and the
right headlight.

And the cap over the filler valve has "Max 8 Nm" on it. 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.

Thanks for all the info, this is what I thought but wanted to get a
second opinion.

 

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.
Good luck, WillemV70 (classic

 

OK, I can see the filler valve, so how do you evacuate the system, and
how much are you supposed to put in?

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.

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.

I have the same problem with my 2000 s70, I can’t find the fill cap on
this model. 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?

Sounds like you're describing the spot to attach a gauge to measure fuel
pressure. Other posts in this thread describe the appearance and
location of the A/C port.
