Description
Radiator fan with variable control for CITROËN C5 II and PEUGEOT 407.
Product Overview
This electric radiator fan assembly with variable speed control is a direct-fit replacement designed for Citroën and Peugeot cooling systems. It regulates coolant temperature more precisely than single-speed units, improving engine thermal management and air conditioning performance. The unit matches original mounting points and electrical interfaces for a straightforward swap on compatible vehicles.
Key Features
- Variable speed control for smoother and more efficient cooling.
- Direct replacement for original equipment part numbers to ensure fit and function.
- Complete assembly including motor and fan shroud for quick installation.
- Designed to restore proper engine temperature regulation and AC performance.

Installation Recommendations
Before starting, ensure the engine is cool and disconnect the battery. Typical replacement steps: remove undertray or bumper access panels as required, unplug the electrical connector, unbolt the fan assembly from the radiator/shroud, remove the old unit and fit the new assembly in the same orientation, reconnect the electrical connector and any mounting clips, then reconnect the battery. After installation, verify fan operation by bringing the engine to operating temperature or running the A/C system, and check for proper airflow and any stored fault codes. Use manufacturer torque settings where specified and inspect wiring, fuses and relays during replacement.
Why The Part Commonly Fails
Common failure causes include bearing wear or seized bearings, motor brush or commutator wear (on brushed motors), water ingress or corrosion on electrical contacts, damage from debris, and failure of the integrated speed control electronics. Excessive load due to clogged radiators or a failing thermostat can accelerate wear. Symptoms of failure include unusual noise, fan not starting, continuous running, or engine overheating.
Practical Notes For Mechanics and DIYers
When replacing the fan, also check the condition of the radiator, fan shroud, wiring harness and related fuses/relays. Replacing the fan as a complete assembly reduces diagnostic time and ensures correct blade balance. For consistent results, test the cooling circuit under real operating conditions and clear any related fault codes after replacing the unit.
