Test M: Coolant Temperature Gage Always Indicates Cold

Disconnect the Coolant Temperature Sender and ground DK GRN/WHT (135) wire at the Coolant Temperature Sender Connector.
^ If Coolant Temperature Gage reads HOT, replace Coolant Temperature Sender.
^ If Coolant Temperature Gage does not read HOT, check DK GRN/WHT (135) wire for an open. Replace the Instrument Cluster if the wire is good.
