It'll be screwed in to either the engine block or the intake manifold. The part showing will probably be about the size of a nickel and protrude about 1/2 - 3/4 of an inch. Will probably have a single wire running to it and either be a spade connector (pull off) or could have a small nut and washer holding a connector on. When you locate it, disconnect the wire to it and ground the wire, either directly or using a small jumper wire. The temp gauge should go all the way to the top. If you ground the wire and the temp gauge does nothing you have a problem either in the wiring or the gauge.

If you can't find it, go to the auto store and ask them to show you one so you will know what it looks like.

Just turn to on to test. No need to start the engine. You will need to drain the coolant down to just below the level of the sending unit if you want to change it without having coolant run out when you take it out.
