Defect

On certain transit buses, there is a possibility that the hydraulic line coming from the radiator fan motor to the cac motor is rubbing on the chassis.

Safety risk

This rubbing may cause the hydraulic line to be rubbed through resulting in a leak and a loss of hydraulic fluid. This fluid could ignite if it comes in contact with a hot source.

Remedy

Dealers will install a p-clamp on the radiator motor support bracket that holds and secures the hose away from the chassis eliminating the possibility of chaffing. The recall began on august 24, 2005. Owners may contact optima at 1-888-391-1777.
