Cleaning between the radiators for airflow is one thing .The other is if there is buildup of debris which is left it will eventually corrode the radiator core tubes which will leak, then a new radiator is required. Mesh grills on the air intakes are a good idea and easy to make and fit by tying to the existing intake bars.
