Check and Clean Radiator Fins

  1. CAUTION: Always wear eye protection when servicing the engine and when using compressed air or high-pressure water. Dust, flying debris, compressed air, pressurized water, or steam can injure your eyes.

    CAUTION: Avoid injury! Compressed air can cause debris to fly a long distance. Wear eye protection when using compressed air for cleaning purposes. Reduce compressed air pressure to 210 kPa (30 psi).

    A - Compressed Air

    Be careful not to damage the fins with the compressed air (A).


  2. If there is a large amount of contamination on the fins, apply detergent, thoroughly clean, and rinse with tap water.

    NOTE: Never use high-pressure water or compressed air at greater than 210 kPa (30 psi) or a wire brush to clean the radiator fins. Radiator fins damage easily.
