[s-cars] Help with the Evil T shaped coolant connector

When you re-assembled yours, the clip went in with a little
hand pressure?

I have tried assembling the pieces without the 'O' ring, so
that the sensor sits even further down in the socket, but the
clip still doesn't fit.

I had to cut the sensor out of the old plastic t fitting to
remove it, so I can't try to reassemble all the old pieces.
Not ever doing this before, I thought the sensor might screw
in, when it just spun and spun, I tried pulling it out with
some needlenose pliers. It didn't want to come out, and I
didn't want to break the plastic on the sensor, so I hacked
the old connector plastic away to expose the sensor. Thats
when I discovered it's just a compression fitting, with the
retaining clip holding things in place.

It seems to me that the clip rests at the junction of the
cylindrical part of the blue plastic and the metal cylinder of
the sensor.  The rectangular part of the blue plastic sensor
is slightly smaller in width, and the clip fits much easier
around that portion, but I don't think that is the proper
place for 2 reasons,

1. The green wiring harness connector would interfere with the
installation in this location (I think)
2. The sensor and O ring would have to sit even further down
in the socket. I've already used alot of my weight (180lbs) in
pressing down on the assemble in an effort to mash the sensor
as far into the socket as possible.

And yes Bill, I did remove the old 'O' ring and installed the
new one. I even tried using the old 'O' ring - No Joy.

Here is a link with some pictures I have X-posted to Audiworld.
