Disconnect connector at coolant temperature sending unit located near thermostat housing. Connect a 12-volt, 3.4-watt bulb (light) between ground and Yellow/White wire. Turn ignition switch to ON position. Ensure bulb lights and temperature gauge needle fluctuates several seconds later. If gauge does not function as specified, check fuses, wiring, connectors and instrument panel circuit board. If these components test okay, replace coolant temperature gauge.
