Did you bleed the system?
There is a temp sending unit, location in the diagram below. One wire connector, green wire. Take the connector loose, you can use a couple different size resistors, one at a time, to see if the temp gage will react properly. If it doesn't, could be something wrong with wiring--connector-- instrument. It could be something wrong with sending unit, I can't be sure without testing.
