99 S70 airconditioner recharge

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.

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.
