Engine Coolant Temperature Gauge

IMPORTANT: Prevent possible engine damage from overheating. If needle on gauge rises into red zone, reduce load on engine to reduce coolant temperature. If temperature remains in warning zone, stop engine and investigate cause.

A - Engine Coolant Temperature Gauge

Engine coolant temperature gauge (A) indicates current engine coolant temperature when key switch is in ON position.

When engine coolant temperature rises above 105 °C (220 °F), caution indicator light on corner post comes on and a pulsed audible alarm sounds. The caution light remains on until coolant temperature falls below 100 °C (212 °F).

If engine overheats, reduce load on engine by reducing ground speed. Observe coolant temperature gauge. If needle on gauge remains in warning zone or temperature continues to rise, shut off engine and investigate cause. (See Troubleshooting section for possible causes and solutions. See your John Deere dealer if no obvious cause of overheating is found.)
