Where is the temperature sending unit for 92 GMC 4.3 1500 pickup
SOURCE: I have a 2000 GMC
I think you'll find sender & pump are all one assy. What is the reason for changing. If it's the gauge, have you removed, cleaned contacts & re-attached wire plug at pump/sender assy, to see if it would cure your problem? Personally, it's not something I'd want to do twice in a short time, so if I was replacing one (if parts are available to do so) I'd replace the other, unless difference in price was extreme.

If you are getting the low coolant message you are looking for the coolant level sensor not the coolant temp sensor. I do believe the sensor is in the jug, is it filled to the full line?
