Gauge Always Indicates Cold

Disconnect engine coolant temperature sender connector. Connect fused jumper wire between engine coolant temperature sender connector terminal "A" (Dark Green wire) and ground. See WIRING DIAGRAMS . Turn ignition on. If temperature gauge indicates hot, replace engine coolant temperature sender. If temperature gauge does not indicate hot, repair open in Dark Green wire between engine coolant temperature sender and instrument cluster. If Dark Green wire is okay, replace instrument cluster.
