Technician A says that the radiator pressure cap increases the boiling point of the coolant. Technician B says a faulty pressure cap can cause the coolant recovery system to overflow. Who is correct?

Question

TheoryPractice · Accepted Answer

Both A and B. Both technicians are correct. A pressure cap increases system pressure, which raises the coolant's boiling point. A faulty pressure cap that doesn't maintain proper pressure can cause the recovery system to overflow as the system can't properly contain the expanding coolant.
