Is Your Riviera's Starter Failing?
If your 1980-1987 Buick Riviera refuses to start, the starter motor is a common suspect. However, before you blame the starter, it's critical to ensure your battery is fully charged and the battery cables and connections are clean and tight. Many starting problems on these classic cars stem from simple electrical connection issues that can mimic a bad starter. Once you've confirmed the battery and cables are in good shape, you can look for the specific symptoms of a failing starter.
A Common Issue: Heat Soak
Owners of GM vehicles from this era often report specific issues like slow cranking when the engine is hot, a phenomenon known as "heat soak." This happens when the starter's internal components get too hot from their proximity to the engine and exhaust, increasing electrical resistance and struggling to turn the engine over. If your Riviera starts fine when cold but labors to start after it's been running for a while, you are likely experiencing heat soak.
Choosing the Right Aftermarket Starter
For a vehicle from this era, finding a brand-new original equipment (OEM) starter from a GM dealer is highly unlikely. Your choice will be between new aftermarket parts and remanufactured units. New aftermarket starters are built from all-new components, while remanufactured starters are rebuilt OEM cores with worn or failed parts replaced.
Aftermarket Brand Tiers
When shopping for a new starter, you'll encounter several brands. Here’s a general breakdown of what to expect:
- Remy: Often considered a reliable aftermarket choice, Remy has a long history with GM electrical parts. Many mechanics have good success with Remy starters and alternators, making them a go-to brand for a balance of quality and value.
- BBB Industries: This company is a major remanufacturer of starters and alternators for many parts stores. They supply a wide range of parts that meet or exceed original specifications, and their warranty return rates are reported to be low.
- WAI Global: WAI offers 100% new, OE-grade starters and alternators. User reviews are mixed, with some reporting good quality and others experiencing early failures, which is not uncommon for value-oriented brands. They can be a good budget-friendly option, but quality may vary.
A Note on Engine Differences
The 1980-1987 Riviera was available with several engines, including the Buick 3.8L V6, the Oldsmobile 5.0L V8, and even an Oldsmobile diesel V8. It is critical to ensure the starter you purchase is correct for your specific engine, as they are not interchangeable. Always verify the part fitment for your exact year and engine combination.

Frequently Asked Questions (FAQ)
Why do I just hear a single 'click' when I try to start my Riviera?
A single loud click is a classic symptom of a failing starter solenoid or a weak battery. The click is the sound of the solenoid trying to engage but not having enough power to turn the starter motor, or the motor itself being seized. Always test the battery first before replacing the starter.
Why does my starter grind or make a whirring noise?
A grinding noise suggests that the starter's pinion gear is not meshing correctly with the engine's flywheel, or the teeth on either gear are damaged. A whirring sound where the starter spins but the engine doesn't crank means the starter drive is not engaging the flywheel at all.
Are there any recalls on the starter for the 1980-1987 Buick Riviera?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no open recalls or specific technical service bulletins (TSBs) for the starter motor on the 1980-1987 Buick Riviera. Any issues are typically due to the age and wear of the component.
Can I replace the starter myself?
Yes, for many owners, this is a very feasible DIY job. The starter is typically located on the passenger side of the engine and is held on by two bolts. You will need to safely raise and support the vehicle, disconnect the battery, and have a basic set of sockets and wrenches.
Technical Specifications
The 1980-1987 Buick Riviera used different starters depending on the engine (3.8L V6, 5.0L V8, 5.7L Diesel V8).

It is essential to match the replacement part to the specific engine in the vehicle.
