I have a 92 that is acting strange. Temp from a cold start goes from 0 to past the m on warm after about one mile of driving. It jumps up there not a slow increase. Also seems to change temp. when in give it alote of boost. Temp jumps up then slowly goes back down. I change the head gaskets about 5-6k ago last year. Any ideals?
 
Sending Unit

Check the temperature sending unit,it is located beside the thermostat housing which is connected to the upper rad hose.I had the same problem about 2 years ago.
 
I had the same problem when my radiator was plugged. You could change the thermostat too, but check out the radiator.

p.s. I let the problem go too long and blew a head gasket.
