The spring for the starter contact of the Citroën 11CV/15CV is a crucial component. This spring ensures the correct pressure and recoil within the starter motor, allowing the vehicle to start smoothly. The component must be durable as it is regularly under tension, affecting wear and tear. For older models like the Citroën 11CV and 15CV, using original or high-quality spring components is important for optimal performance and reliability. Replacing this spring in time prevents starting issues and extends the lifespan of the starter motor.
