(Notification Used By Chevrolet Motor Division)

Dear Chevrolet Truck Owner:

General Motors has determined that some 1985 C/K/G/P Light Duty trucks equipped with a gasoline engine or a 6.2L diesel engine that has an engine oil cooler, RPO KC4, may experience failure of the engine oil cooler hose/hoses. During normal operation, the hoses may burst, resulting in a rapid engine oil loss which could result in internal engine damage.

To prevent the possibility of this condition occurring on your vehicle, please contact your Chevrolet Dealer on or after the date shown below to arrange for a service date. Your dealer will inspect the oil cooler lines and replace them if necessary. This service will be completed at no charge to you.

Instructions have been sent to your Chevrolet dealer. It is estimated that parts will be available August 23, 1985. The labor time to inspect your vehicle is about 10 minutes. If it is necessary to replace the oil cooler lines, it will take approximately one (1) hour longer. Please ask your dealer if you wish to know how much additional time will be needed to process your vehicle.

The enclosed Owner Reply Card identifies your vehicle. Presentation of this card to your dealer will assist them in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
