🔍 Key Concepts

• Diesel engine cooling system sequence of actions during overheat • Difference between immediate load-related actions and maintenance/troubleshooting actions • Safety and prevention of engine damage when temperature rises rapidly

💭 Think About

• Which action can you take instantly from the control position without delay or tools? • What step will most quickly reduce further temperature rise and risk of damage before you start detailed checks? • Which options are more like follow-up troubleshooting or reporting rather than the very first response?

✅ Before You Answer

• Identify which choice directly and immediately reduces heat generation in the engine. • Decide which items (strainer, thermostat, calling chief) are more appropriate after stabilizing the situation. • Consider what action an engineer on watch is expected to take without waiting for permission when seeing a rapid temperature increase.
