Cleaning

Install steel or brass plugs in the transmission oil cooler fittings before cleaning and keep them installed during the entire service operation.

NOTE: With the introduction of a new radiator braze process, there is no longer an approved service method for repairing radiator core leaks. Due to the type of flux used during brazing, the two component epoxy material previously used will not adhere to the aluminum radiator core. If the radiator core leaks, the radiator should be replaced.

EXTERNAL
Clean outside of aluminum core with a soft bristle brush, warm water and a mild household liquid detergent. Rinse with clear water.

NOTE: Do not use a metal brush to clean an aluminum core. Use only horsehair, bristle or nylon brushes.

INTERNAL
Internal cleaning of the aluminum tubes can be accomplished with sonic cleaning equipment. Rinse the core with clean water when completed.

NOTE: Do not use caustic cleaning solutions or copper/brass radiator cleaning agents on aluminum radiators.
