It is located at the thermostat housing single wire plug and the upper radiator hose goes to the housing to keep it simple.
Coolant temperature sensor is locatedat the front of the intake manifold near the upper radiator hose.
only 3 reasons a temp gauge wont work the temp sender is bad the gauge is bad or the wire from temp sender to gauge is broken

Take wire off temperature sender look a guage. If guage at cool, temp sender needs replacement. If guage still at hot, temp sender wire shorted to engine or vehicle body.
Does anybody know the answer to this question??????? YES I HAVE THE ANSWER...REPLACE THE TEMP GUAGE. ITS NOT AS HARD AS YOU WOULD THINK...ABOUT A 20 MIN. JOB ------------------------------------------------ I tried replacing the temp gauge but that wasn't the problem for me. On top of the engine is a temp sender that is all so easy to get to but it is for the engine computer. The temp sender for the gauge is under the water pump. My temp sender went bad because the water pump started leaking. It is like the engine is headed for a major problem of over heating but it disables the temp sender which warns the driver of over heating. It is not easy to change the temp sender but it is doable if you pull off the thermostat housing. Don't put the old thermostat back in. Also, don't get an aftermarket temp sender, I got one and it reads 3/4 hot all the time. It only cost me $5 but I wish I had have bought from the dealer what ever it cost.
where it the temp sensor sender located on a 2001 gmc Jimmy
Most intake manifolds have a couple of pipe plugs in them. Put the sender in one that isn't needed for anything else.

Temp sender on the 289 should be located at the front of the intake manifold. Source: www.AverageJoeResto.com
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
There are numerous sensors (two water temp fan switches, temp sender, oil pressure, etc). What sensor are you asking about?
It is the little conecter next to the thermostat housing, (upper rad hose area)
