Coolant Level Switch PDF

A technical documentation that provides detailed information about the coolant level indicator electronic switch (S41) for Model 163 vehicles. The document includes images and descriptions showing the integration of the switch into the coolant reservoir and explains the switch's design and function. The switch consists of two electrodes that monitor the coolant level by detecting changes in test current, which are evaluated by the vehicle's instrument cluster. An alternating current is used to prevent electrode disintegration.
