[s-cars] Is this a temp sensor?

[Matt twentyV]

sounds like you are talking about the radiator thermo-switch:

It controls the fan speed.

radiator (drivers side). It has brass round part which threads into the
radiator, with three prongs under a plastic housing. It seems that the
shrapnel from my recently deceased fan cracked the plastic housing for the
electrical plugs on this part (and also shredded the plug from the car which
attaches to the part). I'm guessing it's a temp sensor.

I'm hoping to get the "official" name of this part as well as a part number,
plus the either splice in a new electrical plug or fabricate a solution so I
can connect the wires from the car to the part. If I do the latter, I'll
need the order (from drivers side to passenger side) that the wires should
be in. See my bastardized diagram below. Finally, if anyone has the car-side
wires and plug which attaches to this part so I can splice that into my
system, and wants to sell it, I'd be appreciative.

These are the wires that go to the sensor from the car. The plastic
connection that they all ran through to plug into sensor receptor (see
below) got destroyed.

This is what the back of the sensor where the wires from the car plug in.
There is obviously a right and left side, meaning the wires have to be
connected to the correct prongs.

Thanks!
