Troubleshooting
Radiator fan does not turn on
Check electrical connection to the switch. Verify switch is receiving power. Test the switch functionality with a multimeter or by replacing it if faulty.
Radiator fan stays on constantly
Inspect the electrical connection. The switch might be faulty and stuck in the 'on' position. Test and replace if necessary.
Engine is overheating, but fan seems to operate
While the switch might be functioning, an overheating issue could stem from other cooling system components (e.g., thermostat, water pump, radiator blockage). Inspect these other parts.
Coolant leak around the switch
Ensure the switch is properly tightened. Check the threads for damage. If the leak persists, the switch may need replacement.

Setup, Compatibility & Care Instructions
Compatibility Check: Before installation, verify that your vehicle's original radiator fan switch matches the OEM part numbers TOYOTA 8942806010 or 8942833010. The thread size is M16 x 1,5, and the spanner size required is 21mm.
Installation:
- Ensure the engine is completely cool to avoid burns.
- Locate the existing radiator fan switch in the cooling system.
- Disconnect the electrical connector.
- Carefully unscrew the old switch using a 21mm spanner. Be prepared for a small amount of residual coolant to escape.
- Clean the mounting threads in the engine.
- Screw in the new Ci Ignition XEFS312 switch, tightening it securely with the 21mm spanner. Do not overtighten.
- Reconnect the electrical connector.
- Refill any lost coolant and check for leaks after running the engine.
Care: This is a non-serviceable component. Care primarily involves ensuring its correct installation and ensuring the cooling system is free of contaminants that could affect its operation. Regular coolant checks and changes, as recommended by your vehicle manufacturer, will help maintain the overall health of the cooling system and prolong the life of the switch.
