CAMPAIGN: BRAKE PIPE CONTACTED BY ENGINE OIL

NOTE: GM OF CANADA CAMPAIGN 97012 IS LOCATED BELOW THE U.S. VERSION

PRODUCT SAFETY CAMPAIGN

SUBJECT: 97012 - BRAKE PIPE CONTACTED BY ENGINE OIL COOLER HOSE ------------------------------------------------------

MODELS: 1997 G VANS WITH 6.5L TURBO-CHARGED DIESEL ENGINES (L65) --------------------------------------------------------

The Highway Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the customer 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 customer may be entitied 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 remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the divisional letter that is being sent to customers, the customers are being instructed to contact the appropriate Customer Assistance Center if their dealer 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 1997 G Vans equipped with 6.5L turbo-charged diesel engines (L65). These vehicles exhibit a condition in which the front left-hand brake pipe may be contacted by the lower engine oil cooler hose. With contact, the oil cooler hose could wear a hole in the brake pipe during the life of the vehicle causing a loss of front brake performance and increased stopping distances. Partial loss of braking at a time when minimum stopping distance is required could result in a vehicle crash without prior warning.

To prevent the possibility of this condition occurring, dealers are to install an engine oil cooler hose bracket to prevent the lower engine oil cooler hose from contacting the brake pipe, and inspect the brake pipe for wear, and if required, replace the brake pipe.

VEHICLES INVOLVED

Involved are certain 1997 G Vans equipped with 6.5L turbo-charged diesel engines (L65). Involved vehicles are listed below:
