Why a Liquid Cooled System Is Pressurized?
Automotive cooling systems are pressurized because regular coolant has a low boiling point, which isn’t great for keeping an engine cool. Pressurization helps by making the coolant better at its job. When it’s pressurized, like around 15 pounds per square inch (PSI), the coolant doesn’t boil as easily. However, this means it can do a…
