AI Explanation
The correct answer is D) adjusting the radiator louvers. In a diesel engine closed fresh water cooling system with a radiator, the proper water temperature can be obtained by adjusting the radiator louvers. The radiator louvers control the amount of airflow across the radiator, which in turn regulates the cooling of the engine's fresh water coolant. By adjusting the louvers, the engine's operating temperature can be maintained within the proper range. The other options are not correct methods for obtaining the proper water temperature in this type of cooling system.
