Cleaning
Warning! NEVER spray water on a hot radiator. The resulting steam may cause injury.
Note: The radiator fins are used to ensure proper heat transfer. Do not brush the fins. This may damage the fins and reduce heat transfer.
Important: Remove insects, leaves, dirt and other debris with a jet of compressed air from the engine side of the radiator
In some cases, warm water and a mild detergent may be needed.
- Clean the radiator cooling fins.
- If there are damaged cooling fins, they need to be straightened.
