How A Coolant Reservoir Works - The coolant reservoir is a vital component of the cooling system. Its function is to store excess coolant fluid until required. Heat and engine vibration can damage plastic overtime causing cracks and leaks. This coolant expansion tank gives additional coolant a place to go after expansion and contraction due to temperature change.
