Disconnect connector to the Coolant Temperature Sender.^ 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 (135) wire for a short ground. Check the BLK (150) wire at Instrument Cluster connector C2, terminal 15 for a good ground. If both wires are OK, replace the Instrument Cluster.
