I did this yesterday along with all of the fuel lines in the engine
compartment, injector seals, plugw, wires, cap and rotor, adjust idle switch
and replace air filter. (still failed seattle emissions with high
hydrocarbons) 02 sensor and maybe cat converter next, any suggestions
anyone? Anyway....

I replaced the temp II sensor from above. A little rectangular, open at one
end, wire clip holds the sensor in. I was able to remove this with a small
flat tip screwdriver. Do this with the engine cold by the way. Don't want
any pressure in the cooling system. Have your new sender ready with the o
ring on it. With the new sensor in some of my left fingers I was able to
grip the old one with my remaining left fingertips, pull it out, let it go
and push in the new sensor in one smooth (yeah right!) motion. I kinda
practiced how I was going to manipulate the new sender into the hole before
actually pulling the old one. I don't think I lost any more than a couple
tablespoons of coolant. I did not remove and reattach the wiring plug until
after making the switch. Don't forget to put the locking clip back in!
