Citroën/Peugeot 6445ZA Fan Regulator

Description

Product Overview

The Valeo Fan Regulator Resistor 6445ZA is an essential component designed specifically for Citroën and Peugeot vehicles, notably the Citroën C1 and Peugeot 107 models. This regulator controls the speed of the cooling fan, enabling efficient heat dissipation from the engine bay to maintain optimal operating temperature.

Function and Importance

The fan regulator resistor manages electrical current to the radiator fan motor, allowing multiple fan speed levels rather than a simple on/off function. Proper fan regulation improves cooling system efficiency, reduces engine overheating risks, and helps maintain passenger comfort by ensuring consistent operation of the vehicle’s climate system.

Common Failure Causes and Replacement

Over time, the resistor may degrade due to electrical wear, heat exposure, or corrosion, which can cause the fan to operate only at full speed or not run at all. Symptoms of failure include unusual fan speeds, engine overheating, or the climate system not performing correctly. Replacing the fan regulator resistor promptly restores proper fan control and prevents potential engine damage.

Installation Notes

Replacing the fan regulator is a straightforward procedure typically requiring access to the cooling fan assembly behind the radiator. Disconnect the battery before starting the replacement to ensure safety. Remove the faulty resistor module and install the new Valeo 6445ZA regulator, reconnecting all electrical connectors securely. It is advisable to check the entire cooling fan circuit for any additional faults during replacement.
