I warned you when you said your other sensor was held in by 2 clips that
you might have pulled the clip for both sensors by mistake. There is no
substitute for shining bright light on the work area and raising that
side of the van so you can actually get under there to see what you are
doing. Someone who has done this job a bunch of times might be able to
get it done by feel but that risks messing it up.

Did you use new o-rings on the sensors? Did you somehow get 2 o-rings in
there so now the sensor can't go in far enough to be captured by the clip?

The only thing I can think of is the o-ring must not be pushed all the way back and the clip holds between the unit and the o-ring. But I don't see how this would prevent the unit coming off? The other possibility is the coolant temp sensor and temp II sensor clips are not interchangeable and I got them mixed up (they looked the same to me).
