Description
Engine cooling fan with variable control for Citroën Xsara Picasso 1.6 HDi 80 kW
Overview
This electric radiator fan with variable speed regulation is designed to maintain optimal engine temperature on Citroën and compatible Stellantis applications. Built for workshops and DIY mechanics, the unit replaces the original cooling fan on vehicles using part number 1253G4 and restores reliable airflow through the radiator and intercooler for improved cooling performance under load and in traffic.
Function And Benefits
- Variable Speed Control: Adjusts fan revolutions according to coolant temperature and air conditioning demand, improving fuel efficiency and cabin comfort.
- Direct Electric Drive: Eliminates mechanical drag associated with belt-driven fans, reducing parasitic losses on the engine.
- Improved Cooling Response: Faster heat extraction during idling and slow-speed operation, protecting the turbocharged HDi engine from overheating.
- Easy Fitment: Designed to match original mounting points and electrical connector for a straightforward replacement on compatible models.
Fitment And Compatibility
Typical Application:
- Citroën Xsara Picasso 1.6 HDi (80 kW)
Part Number Commonly Used: 1253G4. Also found across certain Stellantis Citroën and Peugeot platforms where the original equipment part number corresponds to this fan. Always check the part number when searching as this unit is frequently located by catalog code 1253G4.
Replacement Procedure
- Prepare Vehicle: Park on a level surface, engage parking brake and allow the engine to cool.
- Electrical Safety: Disconnect the negative battery terminal before any electrical work to avoid short circuits.
- Access Fan Assembly: Remove engine covers, undertray or intake components as required to reach the fan shroud.
- Disconnect Wiring: Unplug the fan electrical connector and any temperature sensor leads routed nearby.
- Remove Fasteners: Unbolt the fan shroud/mounting screws and lift the fan assembly out carefully to avoid damaging the radiator fins.
- Install New Fan: Fit the replacement assembly, secure all fasteners to the manufacturer’s torque recommendations, and reconnect the electrical connector.
- Test Operation: Reconnect the battery, start the engine, and verify fan operation under warm-up and air-conditioning load. Check for abnormal noise or vibration.
Common Failure Modes
- Motor Wear: Bearings and brush wear in the electric motor lead to noisy operation or complete seizure over time.
- Electrical Faults: Corroded connectors, damaged wiring, or failed fan resistors/controls can prevent proper speed regulation.
- Overheating And Contamination: Debris, oil, or coolant contamination can impede fan blades and reduce cooling efficiency.
- Control Signals: Faulty temperature sensors or fan control modules may cause intermittent running or no operation.

Why The Part Fails Most Often
The most common causes of failure are motor wear and electrical issues. Bearings degrade over time, especially in high-mileage or harsh environments, causing increased noise and eventual seizure. Corrosion of connectors, damaged wiring, or failures in the fan control circuit can prevent correct speed regulation. Contamination from coolant leaks or oil can also reduce fan efficiency and lead to premature failure. Regular inspection during cooling system service helps detect early signs of wear.
Conclusion
This variable-control engine cooling fan is a direct solution for restoring proper thermal management on Citroën Xsara Picasso 1.6 HDi 80 kW vehicles where part number 1253G4 is required. Suitable for professional workshops and experienced DIYers, the replacement improves engine reliability, prevents overheating, and ensures correct operation of the cooling system under varied driving conditions.
