Where is the coolent sender sensor located on a 1992 regal 3.8?

Look under the throttle body area. It will have two wires,one yellow,one black.

What about on a 95 Lumina 3.1?

I know the 95 is in the same general location..It also has a yellow and black wire.My wife's 95 3100 Grand prix coolant sensor was a pita to change,almost like somebody used a 1" breaker bar to tighten it.

Hehe, Thats the one with the idiot "low coolant" light sensor correct?

[3.4dohc]

No,coolant sensor tells the computer the temp. Low coolant sensor is a small,about 3x3x1, black plastic box on the left side of the rad (standing in front) under the filler neck.Mine has a black wire with a small white stripe and a yellow wire with a small black stripe.
