Is upper radiator hose very warm (180*)? If not install thermostat. To check gauge take wire off sending unit and use jumper wire to ground. Turn key on, the gauge should go to hot. Do not let gauge peg. Gauge works then replace sender. Doesn't work check continuity to gauge, if good replace gauge.
