Product Information

Full details

This CI Ignition Radiator Fan Switch (XEFS320) is designed for vehicle owners and mechanics needing a reliable temperature-activated switch for their radiator fan. Its key benefit is ensuring efficient engine cooling by automatically engaging the fan at a precise temperature (92°C) and disengaging it at another (87°C), preventing overheating. A potential caveat is its specific compatibility requirements, necessitating verification against your vehicle's OEM part number.

Troubleshooting

Radiator fan not turning on

Verify the switch's temperature ratings (92°C on, 87°C off). Check the electrical connection to the switch and the fan motor. Test the switch's continuity using a multimeter when the engine is hot and cold, or when submerged in hot water, comparing readings to expected values. Ensure the coolant level is adequate.

Radiator fan stays on constantly

The switch may be faulty, stuck in the 'on' position. Check for proper electrical grounding. Inspect the wiring harness for any short circuits. If the switch itself is confirmed faulty, it needs replacement.

Engine overheating, fan cycles improperly

Confirm the switch is the correct part for the vehicle and is installed properly. Check for obstructions in the radiator or fan shroud. Ensure the coolant is fresh and properly circulated. The thermostat may also be a contributing factor.

  • Broad range of cross-reference numbers simplifies part identification.
  • Robust design for long-term reliability.

Cons

  • Specific temperature activation points may not suit all vehicle modifications.

Setup, Compatibility & Care Instructions

Compatibility Verification: Before installation, confirm that your vehicle's original equipment manufacturer (OEM) part number matches HONDA reference 37761PDAE01 or that your vehicle model is listed as compatible (e.g., HONDA ACCORD Mk VII Hatchback (CH, CL) 1.8 i (CH6)). Cross-reference the CI Ignition XEFS320 part number with established aftermarket part databases if your vehicle is not explicitly listed but uses a compatible reference number.

Installation: Installation typically involves draining a portion of the coolant, removing the old switch from the radiator or engine block, and installing the new XEFS320 switch. Ensure the threads are clean and properly sealed to prevent leaks. Reconnect the 2-pin round electrical connector securely. After installation, refill the coolant system and bleed any air pockets according to your vehicle's service manual.

Care: This is a sealed component designed for long-term operation. Regular maintenance of your vehicle's cooling system, including coolant flushes and inspections for leaks, will indirectly protect the switch. Avoid direct exposure to harsh chemicals or high-pressure cleaning near the switch and its electrical connector.
