Here's the way I remember this...on an 85 SL. the sensor has a top "grate" and the bottom part fits into it, it can be pulled apart. Then, the top part pops off from the top. Once I had the cap EXACTLY where I needed it, I marked the underside of a cap with a paintbrush up through the (now sans sensor assembly) hole in the dash. I deliberately went a little smaller than needed and then adjusted this later when the dashcap was RTV'd down, by trimming with a cable-operated Dremel-like tool. That ABS plastic is VERY tough. You need a very small tool to trim with because there really isn't much room to work with there.
Btw, be careful with the thermistor, it's very delicate. And contrary to what you might read, no, you can't get one with the proper temp/resistance curve from Radio Shack for $2.00.
If you search this site, you will find pictures of this sensor and the (usually deteriorated) hose associated with it.
