What is the function of installing a pressure water tank cover in the engine cooling system?

Installing a pressure water tank cover in the engine cooling system serves the crucial purpose of increasing the boiling point of the coolant. When the system is pressurized, it raises the boiling point of the water in the cooling system significantly. This is important because it allows the engine to operate at higher temperatures without the coolant boiling over and causing overheating.

The ability to withstand higher temperatures before boiling helps in maintaining optimal engine performance, as the cooling system can effectively dissipate heat from the engine components. A pressurized system thus contributes to improved engine efficiency and longevity by preventing overheating and potential damage due to a boiling coolant.

Understanding this function highlights the importance of maintaining proper pressure in the cooling system, as a failure to do so can lead to a host of engine problems.
