Visual Inspection

The following inspections should be made before loading the container or trailer:

  • FUEL: The diesel fuel supply must be sufficient to guarantee engine operation to the next check point.

  • Engine Oil: Engine oil level should be at the FULL mark. Never overfill. The dipstick is attached to the filler cap.

  • Coolant: Engine coolant must be above the ADD mark with antifreeze protection of -34 C (-30 F). Check and add coolant in the expansion tank.

  • Battery: Terminals must be clean. Electrolyte should be at the full mark.

  • Electrical: Electrical connections should be securely fastened. Check wires and terminals for corrosion, cracks or moisture. Repair or replace if necessary.

  • Structural: Visually inspect the unit for leaks, loose or broken parts and other damage. The radiator coil should be clean and free of debris. Clean if necessary. Use an air or water spray jet directed against the coil from the air discharge side.

  • Mounting Bolts: Check the mounting bolts on the unit and engine. Tighten if necessary.

    Caution
  • Hazardous Pressures
  • Do not remove expansion tank cap while coolant is hot.
    Caution
  • Risk of Injury
  • Do not remove the radiator cap while the engine is hot.
    Notice
  • System Contamination
  • Do not add GREEN or BLUE-GREEN conventional coolant to cooling systems using RED Extended Life Coolant, except in an emergency. If conventional coolant is added to Extended Life Coolant, the coolant must be changed after 2 years instead of 5 years.
    Notice
  • Equipment Damage
  • Air pressure or water spray must not be high enough to damage coil fins.
