What is the total number of degrees Fahrenheit per pound of coolant that a radiator pressure cap raises the boiling point?

The correct answer indicates that a radiator pressure cap can raise the boiling point of coolant by 6 degrees Fahrenheit per pound of pressure. This temperature increase occurs due to the principle that increasing pressure within the cooling system raises the boiling point of the coolant.

When a radiator is under pressure, the coolant is able to withstand higher temperatures without boiling. This is critical to the efficient operation of an engine, as it allows the cooling system to maintain optimal temperatures, prevent overheating, and improve overall performance. The additional boiling point elevation assists in maintaining effective cooling during extreme conditions, which is vital for engine longevity and efficiency.

Understanding this concept is essential for equipment operators, as it helps them recognize the importance of maintaining proper pressure within the cooling system and the role that the pressure cap plays in managing engine temperature effectively.
