Description
This Electric Coolant Pump is designed to circulate coolant that heats the intake air, improving engine efficiency and performance. It is a crucial component in the cooling system of Citroën and Peugeot vehicles, ensuring stable engine temperature and preventing overheating.
Compatibility and Application
The pump is compatible with multiple PSA group car models, including Citroën C4, C5 (first to third generations), and Peugeot 307. It is commonly sought after by mechanics and DIY enthusiasts by its product codes 9640937480, 144201, and 144207.
Function and Maintenance
The pump’s main function is to pump coolant to the heating circuit of the intake system, warming the air entering the engine. This process helps improve combustion efficiency, especially during cold starts. Failures may occur over time due to wear of internal components or electrical issues, usually noticeable through reduced heating efficiency or engine overheating symptoms.
