I can't believe all this discussion over this o-ring. The o-ring gets
seated into the bottle housing. Just lube the ring with some coolant and
tighten the sensor until the hex bottoms on the top of the bottle. You
will feel it.

Subject: Re: Torque on coolant level sensor?

If you want to get really fancy:  A standard O-ring (which this is not)
is normally compressed around 20%.  So if you measure the thread pitch on
the sensor and the thickness of the O-ring, you can figure out how much to
tighten the sensor after it touches the O-ring in order to get 20%
compression.
I would definitely put some coolant or something on the O-ring to allow it
to
turn easily.
