Maintaining the anti-freeze coolant is an important aspect of a healthy cooling system. This involves one of the most basic components of the automobile, the radiator pressure cap. The cap keeps cooling system pressure at the recommended pressure rating for the car. Each pound of pressure exerted on the cooling system raises the boiling point of the coolant by 3 degrees at sea level. This allows the cooling system to operate at a higher temperature before boiling over, increasing the system’s efficiency and reducing emissions.
