According to Technician A, what is the effect of pressurizing the cooling system?

Pressurizing the cooling system enhances the coolant's ability to absorb and remove heat from the engine. This occurs because the boiling point of the coolant is elevated under pressure. Consequently, the coolant remains in a liquid state at higher temperatures, which allows for more effective heat transfer away from the engine components. As a result, the overall cooling efficiency is improved, helping to maintain optimal operating temperatures for the engine.

While other options might relate to different aspects of engine performance or coolant properties, they do not directly address the primary outcome of pressurizing the cooling system, which is to enhance heat removal efficiency.
