Temperature Indicator (1966-67)

Place a thermometer in coolant in radiator filler neck. Start engine and allow it to run until the thermometer reads a minimum of 180°F. The instrument panel gauge should indicate within the normal band. If gauge does not indicate, short sender unit wire to ground momentarily.

NOTE: Do not leave wire grounded longer than necessary to make test, as gauge may be damaged.

If gauge now indicates, sender is defective or not properly sealed to engine. Be sure to use an electrically conductive sealer (C3AZ-19554-B). If gauge does not indicate, then IVR, gauge or wiring is defective.
