What is the function of the coolant reservoir?

The function of the coolant reservoir is to minimize coolant loss. The coolant used in automotive cooling systems is a long-lasting antifreeze and anti-corrosion solution that not only prevents water from freezing but also reduces scale formation, wear on the water pump impeller, and improves heat dissipation capacity. When the coolant temperature rises and its volume expands, the liquid pressure will push open the radiator valve, allowing coolant or steam from the radiator to enter the reservoir through the steam connecting pipe. When the coolant temperature decreases, the pressure in the radiator drops, and the coolant flows back to the radiator through the intake valve on the radiator cap via the connecting pipe.
