Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. A low coolant level can prevent the engine from reaching its normal operating temperature, reducing the heat available for the heating system. A faulty thermostat can also prevent the engine from reaching the proper operating temperature, similarly affecting the heating system's performance.
