Hi Bill
The reservoir has a lid with a built in removable dip stick. I unscrewed the lid & lifted it off to find a spring about 6" long. I removed the spring by just lifting it out, then reached into the reservoir & removed the small filter sitting at the bottom. I used nitrile gloves as the fluid can be quite messy. My filter had a large metal washer on top of it that the spring sits on to keep pressure on the filter. I popped in the new filter, placed the washer on top of it, then the spring & lid. Very easy actually.
Hope that helps. I have pictures if that would help you.

Hi Jim , I imagine you are chomping at the bit to get going south . I have never checked the ps level on my similar coach , where is that reservoir located ? Thanks Don
