In some instances, the interference fit between the inner wall of the pulley center hole and the water pump drive shaft was not as tight as specified in the drawing specification. This could result in the water pump pulley dislodging from the water pump shaft, which can cause severe engine damage/seizure during vehicle usage.
Dealers will replace the water pump. Owner notification began September 12, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Subaru at 1-800-782-2783.
