- Summary
- 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.
- Consequence
- 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.

Has your Optima been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Optima dealer can also check your VIN. Recall repairs are free.
