Cleaning Radiator Cooling Screen and Fins

CAUTION: Avoid injury! 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: Avoid damage! The radiator cooling screen must be clean to prevent engine from overheating and to allow adequate air intake.


Cleaning Radiator Cooling Screen

IMPORTANT: Avoid damage! Reduced air intake can cause overheating. Keep radiator cooling fins clean.
