Radiator Cleaning

Radiator Cleaning

^ Inspect the condition of all hoses and clamps:
- Inspect the hoses for flexibility and no signs of bulging.
- Inspect the hoses for cracks, cuts, kinks and areas of possible leaks.
- Inspect the brackets, supports, ties and clamps.
- Replace and adjust the hoses and clamps as needed.
^ Clean the front face of the radiator annually.

Important: Do not brush the radiator fins. The radiator fins are necessary for good heat transfer. Brushing damages the fins and reduces heat transfer.

Important: Keep the front of the radiator clear for proper cooling.
^ Clean the front face of the condenser.
^ Remove bugs, leaves, and other foreign material by blowing compressed air through the radiator.
^ Blow the air from the rear toward the front. If compressed air is not available, use a water hose in order to force water through the radiator.
^ Use water only with the engine not running and cool.
