FL-Kruzen Posted April 17, 2016 Report Share Posted April 17, 2016 Hi all, I'm new to the forums because I need your assistance. I'm replacing the ac compressor in my wife's XC90. I have a rebuilt compressor, dryer and a new expansion valve. The problem is that I can not locate the expansion valve! It appears to be inside the firewall. Can I get to it from under the hood? Could I get by without replacing the expansion valve when I install the new compressor? Any advise would be welcomed. Thanks Mark Link to comment Share on other sites More sharing options...
Fran9690 Posted April 19, 2016 Report Share Posted April 19, 2016 You don't need to replace the expansion valve when replacing a compressor. Only real reason you need to replace it is if it failed due to the orifice being plugged by debris. Link to comment Share on other sites More sharing options...
