Hey folks. I am getting ready to take a week long camping trip in some warm country. We did a similar trip a couple of years back in our subaru outback, and wouldn't you know it the AC failed on us in the middle of the trip. I vowed to always double-check my system before taking it on such a journey again.<p>So I looked under the hood of my XC90 (2003 T6), and it wasn't apparent to me where to hook up my can of refrigerant. Furthermore, I pulled up the re-charge instructions on VADIS (volvo software), and the instructions clearly say to only re-fill from the high-pressure port of the system, which my DIY kit says clearly not to do.<p>Anyway, I don't even think that my XC90 needs to be charged, I just wanted to check. But has anybody charged their AC system at home? Or do you need to take it into the dealer??<p>Thanks,<br>Tony

Re: DIY Charging the AC Anyone?? (tpezzolo)

<p>Not hard to do with a proper set of gauges..<p>It is just plain st**id to just dump coolant in. Overcharge the system can cause the system to not function<br>properly and cause damage too.<br>

yes lower pressure fitting only <p>the HP one will cause , any charge you have in your system to be pushed into the can / maybe explode. <p>HP runs anywhere from 80-100psi <br>LP should be running in the 30psi range

Re: (Chilled Man)

Have you recharged the system on an XC90 before? Where is the Low pressure fitting?

There is one on the left side by the belts for low pressure. <p>My dealer said it's ok to use it on the LP, but I'm confused and wish I had had a proper set of gauges, and a drain system.<p>I think mine is low on oil and also has a thermostat problem.<br>

Just loud enough for me to hear, but my wife doesn't notice it and its her car, so it may not be an issue. I would like to check and see if it is fully charged, but I agree, for whatever reason I am confused on this too.
