Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. A missing thermostat would allow coolant to flow through the engine constantly, which would prevent it from reaching the optimal operating temperature. A thermostat that is stuck open would also prevent the engine from reaching the proper operating temperature. Both of these scenarios could cause the engine to overcool.
