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

The aluminum core can be cleaned externally with a soft bristle brush, warm water and a mild household liquid detergent. Rinse with clear water.

If the vehicle is equipped with an automatic transmission, install steel or brass plugs in the transmission oil cooler fittings before cleaning. Keep them installed during the entire service operation.
