Is Your Buick Century's Starter Failing?
When a starter motor begins to fail, it can leave you stranded. The symptoms are often confused with a dead battery, so it's important to know what to look for. On a vehicle like the 1983-1994 Buick Century, decades of use can lead to wear and tear on the starter's internal components.
Common Symptoms of a Bad Starter:
- Single Loud Click: You turn the key and hear one loud "click" but the engine doesn't crank. This often means the starter solenoid is engaging, but the motor itself isn't spinning.
- Rapid Clicking Noise: A fast clicking or chattering sound when you try to start the car can point to a starter that isn't getting enough power, or a failing starter motor. However, this is also a classic sign of a very weak or dead battery.
- No Sound at All: If you turn the key and nothing happens—no click, no crank, but your dashboard lights and radio work—power may not be reaching the starter motor at all.
- Slow, Labored Cranking: If the engine turns over much slower than usual, it can feel like the battery is weak. If the battery is known to be good, this points to a worn-out starter motor that is struggling to turn the engine.
- Grinding or Whirring Noise: A grinding sound can indicate that the starter gear is not meshing correctly with the engine's flywheel, or that the gear is damaged. A high-pitched whirring noise might mean the starter motor is spinning but its gear is not engaging the flywheel at all.
- Intermittent Starting: The car starts fine one day but refuses to crank the next. This can be a sign of a developing electrical problem within the starter motor or a bad spot on the motor's internal windings. A forum user with a 1993 Century noted a similar issue where the car wouldn't start when hot but worked fine after cooling down.
Known Issues, Recalls, and Service Bulletins
For the 1983-1994 model years, there are no specific starter-related safety recalls or Technical Service Bulletins (TSBs) issued by General Motors or the NHTSA. While other issues exist for these vehicles, the starter motor has not been identified as a component with a widespread, documented defect rate requiring a formal bulletin.
Choosing a New Aftermarket Starter
For a vehicle of this age, finding a brand-new OEM (Original Equipment Manufacturer) starter from a GM dealer is highly unlikely. The market primarily consists of new and remanufactured aftermarket parts. Here’s a look at the available brands.
Brand Quality: ACDelco vs. MPA
- ACDelco: As GM's original parts division, ACDelco is a trusted name for Buick vehicles. Their aftermarket parts are generally built to meet or exceed original specifications for fit and performance. Choosing an ACDelco starter, even from their aftermarket lines, is often considered a safe bet for ensuring proper compatibility and reliability.
- MPA (Motorcar Parts of America): MPA is a large aftermarket manufacturer that produces a wide range of starters and alternators under brand names like "Quality-Built". They state their parts meet or exceed OE specifications and are 100% tested. They are a common brand in many auto parts stores and can be a cost-effective alternative.
How Much Does a New Starter Cost for a 1983-1994 Buick Century?
The cost can be broken down into parts and labor. While you can save money by doing the job yourself, it requires working safely under the vehicle.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Starter (ACDelco, MPA) | $75 - $220 |
| Shop Labor | $150 - $300 |
| Total Professional Installation | $225 - $520 |
Frequently Asked Questions
Where is the starter located on my Buick Century?
The starter is located at the bottom front of the engine, at the point where the engine connects to the transmission. You will need to safely raise the front of the vehicle with a jack and secure it with jack stands to gain access from underneath.
Can I replace the starter myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill and the right tools. The process involves disconnecting the battery, raising the car, removing the electrical wires from the old starter, unbolting it (usually two bolts), and installing the new one. You may need a ratchet with a long extension and a swivel joint to reach the bolts.
Does my new starter need shims?
Some older GM vehicles required thin metal shims between the starter and the engine block to ensure proper gear alignment. When removing the old starter, look carefully to see if any shims are present. If so, they must be reinstalled with the new starter in the same position to prevent grinding noises or damage.
Is a remanufactured starter a good option?
A remanufactured starter can be cheaper, but its quality can vary. A "reman" part is an old starter that has been rebuilt with new or refurbished components. Given the reasonable price of brand-new aftermarket starters for the Century, opting for a new unit is generally recommended for better reliability and a longer lifespan.
Technical Specifications
The starter is typically held on by two 15mm bolts and is located where the engine meets the transmission on the front side of the engine bay.
