Flush/replace slide-out fluid
I want to replace the fluid in my slide-outs. The Lippert TI-176 says:
1. Start with clean fluid in reservoir and jacks/rooms in retracted position. [I understand that part!] Remove the bottom (or rear) hose and plug it. Extend jack or room cylinder all the way, catching fluid to avoid mess.
[okay, first question: In the manual it shows the slide-out cylinder with the retract port on the rod end and the extend port on the cap end of the cylinder. I get that the idea is to detach the hose and let the old fluid come out of the cylinder into a catch basin instead of flowing through the hose back to the reservoir. But I am confused as to which way the fluid is flowing here. Is the fluid pushing into the cylinder from the extend port when you extend the slides? If that's the case, then I would need to detach the hose from the retract side? Or when extending the slides, would I detach the hose from the extend port and catch the fluid coming out of that end?]
2. Now, with jack/room extended, push fresh fluid through hose until you know it is clean. Connect to cylinder. Remove the top or front hose and plug it. Fully retract cylinder catching fluid. When fully retracted, push fresh fluid through hose until clean. Connect to cylinder and cycle to eliminate any residual air.
[Step two is the opposite of step 1. If I get step one done, I know to just do the opposite for step 2]
3. Use this process for each jack/room cylinder, one at a time, and this will get the majority of the old fluidvout of the system. No process will be 100% but this should get you to 95+.
Thanks!!
