Explain the function of cooling water expansion tank...

Answer / Amit Srivastava

The cooling water expansion tank is a crucial component in engine cooling systems. Its primary function is to accommodate the volume increase of coolant during evaporation, preventing pressure buildup within the cooling system that could potentially damage components. The expansion tank also allows for air entrapped within the coolant to be released and helps maintain consistent coolant level.
