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

For 1990-2009 cars

# CAMPAIGN: BATTERY LEAKAGE- REPLACE HEAVY DUTY BATTERY

MOOELS: 1985 Buick Electra,, Oldsmobile 98 Equipped with Heavy Duty Batteries

#### TO: ALL AFFECTED DEALERS:

#### DEFECT INVOLVED:

General Motors of Canada has determined that some 1985 Buick Electra Coupes and Sedans and Oldsmobile 98s were assembled with batteries that may leak acid. This acid may cause possible degradation of the transmission cooler hoses on gasoline engine equipped vehicles and other components in the are 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 on gasoline engine equipped vehicles will be replaced and any other battery acid affected component will be cleaned or replaced.

#### VEHICLES INVOLVED:

Certain 1985 Buick Electras and Oldsmobile 98s with 3.0L and 3.8L gasoline engines and 4.3L diesel engines equipped with 107 or 78A-60 heavy duty batteries (UA1 option) within the following VIN breakpoints:

Dear General Motors Customer:

General Motors of Canada has determined that some 1985 Buick Electras and Oldsmobile 98s 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 GM dealer will determine if the vehicle is equipped with an original equipment 107 or replecement 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.

Please contact your GM dealer to arrange a service date. The labour time to inspect your vehicle is approximately five minutes. If the battery and transmission cooler lines are replaced, the labour time is approximately twenty minutes. If additional clean-up or replacement of other components are required, labour time can be up to approximately three (3) hours. Please ask your dealer if you wish to know how much additional time will be necessary to process your vehicle.
