What does cooling system pressurization enable according to Technician A?

Cooling system pressurization is crucial for improving heat transfer from the coolant. When the cooling system is pressurized, the boiling point of the coolant is raised, allowing it to absorb more heat from the engine without boiling over. This helps to maintain effective temperature control within the engine, ensuring that it operates efficiently. The higher pressure enables the coolant to remain in a liquid state at higher temperatures, which enhances its ability to carry heat away from the engine and transfer it to the radiator for dissipation. This principle is fundamental to the effectiveness of the engine cooling system, ensuring optimal operating temperatures and preventing overheating.
