1999 S70 Removing ECU Box to service expansion valve

[volvooh]

It appears to service the expansion valve (and perhaps replace the idler while there) I need to remove the ECU box. Are there any specific steps. This is one thing I don't want to mess up!

Just pull the accordion hose, undo snaps, remove lid, then wiggle the " sidewalls" up. Clear the rear feed hose from the climate unit (attaches to firewall) as you lift.

Leave the ECU and TCU ( if applicable) in place.

That will give you enough space to service the orfice and lines
