Cleaning Radiator Cooling Fins

Avoid injury! Compressed air causes debris to fly a long distance.

  • Clear work area of bystanders.
  • Wear eye protection when using compressed air for cleaning purposes.
  • Reduce compressed air pressure to 210 kPa (30 psi).

Avoid damage! Cooling fins must be clean to prevent engine from overheating and to allow adequate air intake.

  1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)

  2. Avoid damage! High-pressure water or air damages cooling fins or other engine components. Use water from a hose or reduce compressed air pressure to 210 kPa (30 psi).

    Turn off engine before cleaning radiator screen and fins.
