Water temperature sensor
I'm going to install one of these, hopefully it will improve my gas mileage and Power. Does anybody know the easiest way to do this installation? Thanks in advance...

Its all easy, but just a bunch of stuff to get out of the way to do it.
The spark plug wire conduit needs to be out of the way, and to do that the air meter and intake resonator and both cam sprocket / spark plug covers need to be removed all wires unplugged from the caps, top coil comes off, you know all that fun stuff.
It is way easier on a Geo Metro, and old chevy cars and trucks, or should I say faster to do but then the old chevys don't have ECT's.

Interestingly there are multiple sensors, one normal multi wire connector, a single wire connector for the dash cluster and another multi wire connector for another sensor. Any insight?
Also check the condition of the connector pins. I found on another car the pins in the plug where corroded. This was causing a higher resistance and lower temp reading.

this was an easy job. I think I had to take off the throttle body and that was it. Just use a 19mm wrench. My sensor had a bunch of corrosion on it. Warm starts seem to be much quicker now.

I've read many reports on here of people claiming replacing that part make a subjective improvement in something or other. Has anyone ever removed one and bench tested it, confirming a problem with it? I expect they are simple and robust devices that probably don't fail very often.
I replaced mine many years ago, like others, in search of better MPG. I bench tested the old one carefully and it was within spec across a wide range of temperatures. So it was fine, but since I had the new part and was all the way in there, I put the new one in. No butt-dyno or MPG improvements, either, as expected. I _did_ break a few brittle things (vacuum hoses, etc.) on my way in there though.
