Frequently Asked Questions
Can I use an alternator from a 1991 Roadmaster on my 1980s Buick?
No. The 1991-1996 Roadmaster was built on a different platform (the GM B-body) and used different engines, most notably a V8. The alternators are not interchangeable. You must buy the specific alternator for your vehicle's model, year, and engine.
I was told I own a 1987 Roadmaster. What do I actually have?
It is likely your car has been misidentified. During the 1980s, Buick's largest sedans were the Electra and LeSabre. The Electra Estate was a large, rear-wheel-drive station wagon that continued until 1989 and is sometimes confused with the later Roadmaster wagons. Check your VIN and registration to confirm your actual model.
Where can I find parts for my 1985-1989 Buick?
Once you identify your correct model, parts are widely available from auto parts retailers. You will need to search for your specific year and model, for example, "1985 Buick Electra alternator" or "1989 Buick LeSabre alternator."
Why is it so hard to find information on a 1985-1989 Roadmaster?
The information does not exist because the vehicle was not manufactured during these years. The Roadmaster name was on hiatus between 1958 and 1991.
