Note: Bleeding of the fuel system may be required to start the engine.
3. Start the engine and run at 1000-1200 RPM for 30 minutes. Observe the oil pressure and water temperature. If
oil pressure drops below 103 kPa [15 psi], stop the engine and troubleshoot the lubrication system, if water
temperature exceeds 95°C [203°F], stop the engine and allow to cool. Troubleshoot the cooling system.
4. After completing Step 3, stop the engine and inspect for leaks.
