Troubleshooting
Radiator fan does not turn on.
Check the electrical connection to the switch. Ensure the engine coolant temperature is reaching the activation point (95°C). Verify the fan motor itself is functioning correctly by applying direct power.
Radiator fan stays on constantly.
The switch may be faulty, stuck in the 'on' position. Verify coolant temperature is below the shut-off point (100°C). If the issue persists, the switch likely needs replacement.
Leaking around the switch.
Ensure the switch is properly tightened. Check the sealing surface on the radiator or engine block for damage or debris. Replacement of the switch or a new sealing washer may be necessary.
Engine is overheating despite fan operation.
The fan switch may be activating at incorrect temperatures or the fan may not be moving enough air. Verify the switch's operating temperatures. Check for radiator blockages, low coolant level, or a malfunctioning water pump.
