FAQs
What vehicles is the Ci Ignition XEFS328 Radiator Fan Switch compatible with?
This switch is primarily designed for specific BMW models, notably the BMW 3 (E36) 316 i Saloon Petrol produced from 09/1993 to 05/1998. It is also cross-referenced with BMW OEM part number 61318361787 and many other aftermarket part numbers.
What are the temperature settings for this switch?
The switch has a shut-off point at 76°C and a switch-on point at 81°C.
How do I know if my radiator fan switch needs replacing?
Symptoms include the radiator fan not coming on when the engine is hot, the fan running constantly, or the engine overheating. A mechanic can test the switch's functionality.
What is the thread size of this fan switch?
The thread size is M14 x 1.5.
How many pins does the connector have?
This radiator fan switch features a 3-pin connector.
Can I install this myself?
If you have experience with automotive repairs and cooling systems, DIY installation is possible. However, it is recommended to consult a professional mechanic to ensure correct installation and to avoid potential damage or coolant leaks.
Where is the radiator fan switch located?
The radiator fan switch is typically located in the radiator or cylinder head, where it can accurately sense the engine's coolant temperature.
Troubleshooting
Radiator fan not turning on
Check the electrical connection to the switch. Verify the engine temperature is above the switch-on point (81°C). Test the switch for continuity when hot and cold, or replace if faulty.
Radiator fan not turning off
Ensure the engine temperature has dropped below the switch-off point (76°C). If the fan remains on, the switch may be stuck in the 'on' position and needs replacement.
Coolant leaks from the switch area
The switch may not be tightened correctly or the sealing surface might be damaged. Remove the switch, inspect the threads and sealing surface, and reinstall with appropriate sealant or a new sealing washer if necessary. Ensure proper torque is applied.
Engine overheating
While the fan switch is a key component, engine overheating can also be caused by low coolant, a faulty thermostat, a clogged radiator, or a weak water pump. Ensure the switch is functioning correctly and then investigate other potential cooling system issues.

Setup, Compatibility & Care
Compatibility Verification: Before installation, it is crucial to confirm that the XEFS328 Radiator Fan Switch is compatible with your specific vehicle's make, model, and year. Check if your vehicle's original part number matches the BMW OEM reference 61318361787 or if it is listed among the compatible cross-references provided.
Installation: Installation typically involves draining a portion of the coolant, carefully removing the old switch, and installing the new one with its M14 x 1.5 thread. Ensure the new switch is tightened to the manufacturer's recommended torque to prevent leaks. The 3-pin connector should then be securely attached. It is recommended to have this part installed by a qualified mechanic if you are not experienced with automotive cooling system repairs.
Care: This component is generally maintenance-free. However, regularly check your cooling system for leaks and ensure coolant levels are appropriate. Clean any debris from around the radiator and fan area to maintain optimal airflow. Inspect the electrical connector for corrosion periodically.
