What is the maximum RPM to run the engine while back flushing?

• A. 1000 RPM
• B. 1200 RPM
• C. 1500 RPM
• D. 1800 RPM

Answer: (B)

The maximum RPM to run the engine while back flushing is established to ensure optimal performance and safety of the engine's cooling system. Running the engine at a regulated higher RPM, in this case 1200 RPM, ensures that the necessary flow rates are achieved for effective back flushing without risking damage to engine components or the cooling system. At this specified RPM, the engine can maintain sufficient water flow through the system to effectively remove any debris or sediment that may have accumulated. This practice is crucial for maintaining the engine's efficiency and longevity, as any buildup can lead to overheating or other operational issues. Setting the engine speed to this level strikes a balance between effective flushing performance and preventing undue strain on the engine, which would potentially occur at higher RPMs during this operation.
