# CAMPAIGN: UPPER TRANSAXLE OIL COOLER LINE SEPARATION

#### SUBJECT: TRANSAXLE OIL COOLER LINE CORPORATE SEPARATION (27 STATES ONLY) CAMPAIGN #: 95-C-68 -------------------------- DATE: MARCH 1996

YEARS/ 1992 -1993 EIGHTY EIGHT MODELS: 1992 - 1993 NINETY EIGHT SERVICE MANUAL 1992 -1995 SILHOUETTE SECTION: 7A ------------------------

#### TO: ALL OLDSMOBILE RETAILERS

----------------------------

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the included copy of the letter that is being sent to owners, the owners are being instructed to contact OCAN (Oldsmobile Customer Assistance Network) if their retailer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

#### DEFECT INVOLVED

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1992-1993 Oldsmobile Eighty Eight and Ninety Eight model vehicles and in certain 1992-1995 Oldsmobile Silhouette model vehicles located in certain states (see "STATES INVOLVED" section). These vehicles have an upper transaxle oil cooler hose which could pull out of the crimped coupling at the transaxle end of the assembly. Under certain climatic conditions and under certain driving conditions, if this coupling was to separate and an ignition source was present, an engine compartment fire could occur.

To prevent the possibility of this condition from occurring, retailers are to install a new upper transaxle oil cooler line (to transaxle) on all involved vehicles.

#### VEHICLES INVOLVED

#### IMPORTANT: PLEASE ENSURE THAT EACH VEHICLE MEETS BOTH THE "VEHICLES INVOLVED" CRITERIA AND THE "STATES INVOLVED" CRITERIA BEFORE PERFORMING THE SERVICE PROCEDURE.

Involved are certain (not all) 1992-1993 Oldsmobile Eighty Eight and Ninety Eight model vehicles. Also involved are certain (not all) 1992-1995 Oldsmobile Silhouette model vehicles equipped with the 3800 engine (RPO L27) without trailer towing (RPO V92).

Involved vehicles have been identified by Vehicle Identification Number Listings.

Owner name and address data furnished will enable retailers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

These vehicles have an upper transaxle oil cooler hose which could pull out of the crimped coupling at the transaxle end of the assembly.

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
