Identify the maintenance procedures that must be followed for the tender's propulsion system.

The correct answer encompasses a comprehensive approach to maintaining the tender's propulsion system, which is essential for ensuring optimal performance and longevity. Regular inspections allow for routine identification of any wear or damage that could compromise the system's efficiency and safety. Oil changes are critical as they prevent engine wear and maintain lubrication for moving parts, which is vital to operational reliability. Coolant checks are equally important, as the cooling system prevents overheating, a common issue that can lead to severe engine damage if not addressed.

By following these combined procedures, maintenance personnel can proactively address potential issues, thereby enhancing the operational readiness of the propulsion system and mitigating the risk of breakdowns during mission-critical operations. This thorough approach ensures that all aspects of the propulsion system are monitored and maintained appropriately.
