Any last minute input on movovalve removal?

I've done the "search" on monovalve, mono valve, heater valve, 260E, 300E, and several combinations.

I read the great DIY article by Steve Brotherton. (which is troubleshooting but not removal procedures).

I've tried Google.

I'm looking for a paragraph or pictures on how to remove the monovalve (1988 260E for me, or 1989 300e for Benz300).

(Disconnecting the wire connector on top is obvious.)

My only questions are:
1. Do I clamp off the hoses or will fluid loss be minimal?
2. How do I remove the pointy rubber connectors that seem to hold the entire unit in place? Do they slide, stretch, pull, twist (or just eventually break??? -my greatest fear!)

Once I have guidance, or if I can figure it out alone, I'll take pix to post for others.

Thanks a lot,
