Explanation:

First Question (about cooling system and water pump)

• Technician A: The cooling system’s main function is to maintain the engine’s proper operating temperature. This is correct.
• Technician B: The thermostat (not the water pump) opens at its rated temperature to allow coolant to flow through the radiator. So Technician B is wrong.

• Technician A: Cooling fans draw air through the radiator to help transfer heat from the coolant to the air, aiding the heat - transfer process. This is correct.
• Technician B: The radiator transfers heat from the coolant to the outside air (the heat from the coolant is dissipated to the outside air via the radiator). This is also correct.

Answer:

A. Technician A only
