Just changed thermostat. Gauge will run normal for awhile then will shoot up like its over heating. Bad new thermostat or sending unit not working. Don't know where its located

Low coolant level, bad thermostat could cause this. Also, have the head gaskets checked for failure with a leak down test done.
