(Notification used by Chevrolet Motor Division)
Dear Chevrolet Owner:
This notice is sent to inform you that Chevrolet Motor Division is conducting a recall campaign that includes your vehicle.
REASON FOR THIS RECALL
General Motors has determined that 1989 Chevrolet Astros equipped with air conditioning (RPO C60/C69) and 4.3L V6 Engines (RPO LB4) may have the high pressure A/C line (A/C compressor and condenser hose assembly) contacting the positive stud boot on the rear of the generator. If this line causes the stud to push through the boot and contact the line, arcing can occur, causing a hole in the line and total loss of A/C refrigerant.
WHAT WE WILL DO
To prevent the possibility of this condition occurring, it will be necessary to inspect the line for necessary clearances or damage. If no damage has occurred, the line must be relocated as necessary. If damage has occurred, a now A/C line will be installed and relocated. This service will be performed for you at no charge.
WHAT YOU SHOULD DO
Please contact your Chevrolet dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. The labor time necessary to perform this inspection and/or correction may vary from ten minutes to one hour, depending on the amount of service required for your vehicle. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary inspection/correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid 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.
