CAMPAIGN: BATTERY LEAKAGE- REPLACE HEAVY DUTY BATTERY. Buick Electra/Park Avenue 1985

For 1990-2009 cars

# CAMPAIGN: BATTERY LEAKAGE- REPLACE HEAVY DUTY BATTERY

#### MODELS AFFECTED: 1985 ELECTRAS EQUIPPED WITH HEAVY DUTY BATTERIES

General Motors has determined that some 1985 Electra Coupes and Sedans were assembled with batteries that may leak acid. This acid may cause possible degradation of the transmission cooler hoses and other components in the area of the battery.

To prevent these conditions from occurring on vehicles involved, dealers are to determine if the vehicle is equipped with original equipment battery number 107 or aftermarket number 78A-60. If the vehicle is equipped with one of these batteries, they will be replaced with a new 78A-72 battery, the transmission cooler hoses will be replaced, and any other battery acid affected component will be cleaned or replaced.

#### VEHICLE INVOLVED

Certain 1985 Electra Coupes and Sedans with 3.0L and 3.8L engines and 107 or 78A-60 heavy duty batteries (UAI option) within the following VIN breakpoints:

PLANT FROM TO AND INCLUDING ----- ---- ----------------- Wentzville F1 400126 F1 425364

SOME OF THE VEHICLES WITHIN THESE BREAKPOINTS WILL NOT REQUIRE BATTERY REPLACEMENT AS THEY WERE NOT ASSEMBLED WITH A HEAVY-DUTY BATTERY.

#### DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangemerits made to make the required modification according to instructions contained in this bulletin.

#### DEALER MATERIAL

If your dealership has vehicles involved in this campaign, you will receive the following items:

List of all vehicles involved in this campaign shipped to your dealership.

One campaign identification label for each vehicle.

Involved vehicles have been identified by Vehicle Identification Number computer listings. Computer listings contain the complete Vehicle Identification Number, owner name, and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers 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.

#### TRANSFER OF VEHICLE

If a vehicle has been transferred or sold to another location, please forward vehicle information for this vehicle to your Buick Zone Office for handling with the proper dealer.

#### OWNER NOTIFICATION

Owners of vehicles involved in this campaign will be notified by Buick Motor Division (see copy of Owner letters included with this bulletin).

#### CHANGE OF OWNER INFORMATION

Dealers are to use the Dealer Communication System (D.C.S.) to provide Buick Motor Division with subsequent Buick owner information. By reporting a change of owner name or address of a vehicle in campaign status over the D.C.S., the need to send in a C.V.A.R. Form for that vehicle is eliminated. Terminal input instructions are covered in the D.C.S. Manual under Section 9, page 9-JO1A and B.

#### PART INFORMATION

The batteries for this campaign are to be obtained from your local AC-Delco outlet. One 78A-72, part number 1981590, is required for each vehicle that requires a battery replacement. The other parts for this campaign are to be obtained from GMWDD as follows:

Sodium Bicarbonate (Baking Soda) Purchase Locally

#### TECHNICAL PROCEDURE

#### PART A - INSPECTION OF BATTERY

1. Open vehicle hood, cover fenders, and inspect "Caution" label on top surface of battery. Refer to Figure 1.

a. Replace batteries identified as original equipment number "107" or after market (replacement) number "78A-60" on "Caution" label following the complete procedure in PART B of this procedure.

PART B - COMPONENT INSPECTION, CLEANING, REPAIR AND REPLACEMENT

#### CAUTION:

FOLLOW RECOMMENDED PRECAUTIONS IN HANDLING BATTERIES AND POTENTIAL BATTERY ACID CONTAMINATION COMPONENTS. BATTERY ACID IS CORROSIVE. PROPER PROTECTIVE CLOTHING AND SAFETY GLASSES SHOULD BE WORN DURING THE FOLLOWING WORK:

1. Disconnect battery negative cable, positive cable, remove retainer screw and retainer. Carefully remove battery, tag with vehicle information, and store in a safe area for disposition.

2. Inspect the following areas for evidence of battery acid. Make note of areas where acid or acid residue is present. Acid residue can usually be identified as a whitish discoloration or deposit. Acid can result in corrosion or paint peeling on metals and softening and blistering of rubber and certain plastic compounds.

a. Battery tray, holddown bolt, and plastic clamp,

b. Left inner fender area,

c. Left shock tower,

d. Left horns,

Dear Buick Owner:

General Motors has determined that some 1985 Electra Coupes and Sedans were assembled with batteries that may leak acid. This acid may cause possible degradation of the transmission cooler hoses and other components in the area of the battery.

To prevent these conditions from occurring on your vehicle, your Buick dealer will determine if the vehicle is equipped with an original equipment 107 or replacement 78A-60 battery. If the vehicle is equipped with one of these batteries, they will be replaced with a new 78A-72 battery, the transmission cooler hoses will be replaced and any other battery acid affected component will be cleaned or replaced. This service will be done at no charge to you.

Instructions for making this correction have been sent to your Buick Dealer. Parts will be available approximately May 1, 1985. Please contact your dealer after this date to arrange a service date to have your vehicle corrected. The labor time to inspect your vehicle is approximately five minutes. If the battery and transmission cooler lines are replaced, the labor time is approximately twenty minutes. If additional clean-up or replacement of other components are required, labor time will be increased accordingly. Please ask your dealer if you wish to know how much additional time will be necessary to process your vehicle.

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the correction 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.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. 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. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
