Test G: Coolant Temperature Gage Always Reads Hot

Disconnect the Coolant Temperature Sender terminal and turn the Ignition Switch to RUN.
^ If the Coolant Temperature Gage indicates C, replace the Coolant Temperature Sender.
^ If the Coolant Temperature Gage does not indicate C, check the DK GRN/WHT (635) and WHT/BLK (235) wires for a short to ground. If wires are OK, replace the Instrument Cluster.
