Cleaning Radiator Cooling Fins

CAUTION: Compressed air can cause 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).

IMPORTANT: 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. IMPORTANT: High-pressure water or air can damage cooling fins or other engine components. Use water from a hose or reduce compressed air pressure to 210 kPa (30 psi).

    Turn engine off before cleaning radiator screen and fins.
