Description
Engine cooling fan with variable control. For vehicle CITROËN XSARA PICASSO 1.6 HDi 80 kW.
Product Overview
High-quality replacement engine cooling fan designed for Citroën and Peugeot applications. This variable-speed radiator fan provides controlled airflow to maintain optimal engine temperature under a wide range of driving conditions. Built to fit vehicles originally equipped with the 1253G4 fan code, it is aimed at professional mechanics and experienced DIYers seeking a reliable, direct-fit solution for the Xsara Picasso 1.6 HDi 80 kW.
Benefits
- Variable-speed operation ensures smooth, demand-driven cooling and reduced electrical load.
- Direct-fit design simplifies installation and reduces downtime in the workshop.
- Robust motor and blade design for stable airflow and consistent cooling performance.
- Compatible with original mounting points and electrical connectors for straightforward replacement.
How It Works
The unit is an electrically driven radiator fan with variable control (PWM/ECU governed on many PSA vehicles). The fan adjusts speed based on engine temperature, A/C demand and vehicle control signals to maintain optimal cooling and cabin comfort while minimizing noise and energy consumption.
Typical Replacement Procedure
Suitable for professional workshops and competent DIY mechanics. General replacement steps:
- Park the vehicle on a flat surface, apply the handbrake and allow the engine to cool completely.
- Disconnect the negative battery terminal before starting any work to prevent electrical shorts.
- Remove any obstructing components (engine covers, intake ducts or airbox) to access the fan assembly.
- Unplug the fan electrical connector and detach any retained wiring clips.
- Unscrew the mounting bolts holding the fan/shroud to the radiator and carefully lift the assembly clear.
- Install the replacement fan, secure mounting bolts, reconnect the electrical plug and reassemble removed components.
- Reconnect the battery and perform a functional check: start the engine, allow it to reach operating temperature and verify fan operation and absence of unusual noise or vibration.
Mounting Recommendations
- Always Disconnect The Battery Before Work. Remove negative terminal to avoid short circuits or accidental fan startup.
- Check Connector And Wiring. Clean corroded terminals and replace damaged wiring or clips to ensure reliable electrical connection.
- Secure The Shroud Correctly. Improperly seated shroud reduces cooling efficiency and may cause blade contact with surrounding components.
- Test Fan Operation Before Final Assembly. Verify multiple speed steps (idle/A/C demand) and listen for bearing noise or vibration.
- Follow Manufacturer Torque And Retention Instructions. If torque specs are not available, ensure bolts are tightened securely and evenly to avoid stress on the plastic shroud.
Why This Part Fails Most Often
Cooling fans generally fail due to bearing wear, motor overheating or electrical faults. Frequent causes include worn bearings causing noise and reduced rotation, motor burnout after prolonged high-temperature operation, water or road-salt corrosion of connectors, and damaged blades from debris. Variable-speed fans can also be affected by faulty control signals, relays or fuses in the cooling circuit—so always check the electrical system when diagnosing a failed fan.
