A-Premium 17986 Starter for GM 3.0L and 3.6L V6 Vehicles
The A-Premium 17986 starter motor fits select Buick, Cadillac, Chevrolet, GMC, Pontiac, Saturn and Suzuki vehicles equipped with specific 3.0L or 3.6L V6 engines. It is a 12-volt, 1.4-kW clockwise starter with a 12-tooth drive gear.
Fitment is engine-specific. Do not order solely by year and model; confirm the engine, VIN and original starter number.
Vehicle Fitment
Buick
| Model | Years | Engine |
|---|---|---|
| Allure | 2006–2008 | 3.6L V6 |
| Enclave | 2008–2017 | 3.6L V6 |
| LaCrosse | 2010 | 3.0L V6 |
| LaCrosse | 2006–2008, 2010–2016 | 3.6L V6 |
| Rendezvous | 2006 | 3.6L V6 |
The supplied listing’s “Buick Attract” is a mistranslation of Buick Allure, the Canadian-market name used for the LaCrosse during this period.
Cadillac
| Model | Years | Engine |
|---|---|---|
| SRX | 2010–2011 | 3.0L V6 |
| SRX | 2006, 2012–2016 | 3.6L V6 |
| STS | 2006–2007 | 3.6L V6 |
| XTS | 2013–2019 | 3.6L V6 |
Verify Cadillac applications by VIN. Do not assume compatibility with the XTS V-Sport’s twin-turbo engine or other performance variants without matching the original starter number.
Chevrolet
| Model | Years | Engine |
|---|---|---|
| Captiva Sport | 2012 | 3.0L V6 |
| Colorado | 2015–2016 | 3.6L V6 |

| Malibu | 2008–2012 | 3.6L V6 |
| Traverse | 2009–2017 | 3.6L V6 |
“Captiva Recreation” and “Impala Restricted” in the original copy should read Captiva Sport and Impala Limited.
GMC
| Model | Years | Engine |
|---|---|---|
| Acadia | 2007–2016 | 3.6L V6 |
| Acadia Limited | 2017 | 3.6L V6 |

| Terrain | 2010–2012 | 3.0L V6 |
| Terrain | 2013–2017 | 3.6L V6 |
The 2017 Acadia Limited is the carryover version of the original Acadia—not the redesigned standard 2017 Acadia.
Pontiac
| Model | Years | Engine |
|---|---|---|
| G6 | 2007–2009 | 3.6L V6 |
| Torrent | 2008–2009 | 3.6L V6 |
Saturn

| Outlook | 2007–2010 | 3.6L V6 |
| Vue | 2008–2010 | 3.6L V6 |
The supplied “Saturn Charisma” application should read Saturn Aura. Charisma would have been an ambitious factory option.
Suzuki

|---|---|---|
| XL7 | 2007–2009 | 3.6L V6 |

Replacement and Reference Numbers
This starter cross-references:
- 17986
- 17986N
- 12588493
- 12598756
- 12598757
- 12601721

- M000T35872
Match one of these numbers to the removed starter or an authoritative VIN-based parts catalog before ordering. A matching 3.6L displacement alone is not enough because GM used several versions of its High Feature V6 across different platforms and production periods.

Applications That Require Additional Verification
Do not assume this starter fits:
- Four-cylinder versions of the listed models
- Hybrid applications
- Cadillac XTS V-Sport twin-turbo models
- Vehicles with a 2.8L V6
- Chevrolet Captiva Sport model years other than 2012
- Redesigned 2017-and-newer GMC Acadia models
- Any application outside the listed year range
- Vehicles whose original starter has a different tooth count or mounting pattern
Use the NHTSA VIN decoder to identify the vehicle and engine, then compare the OE starter number.
Installation Notes
Before replacing the starter, test:
- Battery state of charge
- Battery terminals and cables
- Engine and chassis grounds
- Starter relay and fuse
- Ignition-switch signal
- Voltage drop on the positive and ground circuits
- Engine rotation by hand
- Charging-system operation
A clicking starter does not automatically mean the motor has failed. A weak battery or corroded cable can produce nearly identical symptoms—and is considerably easier to replace before the intake and exhaust plumbing begin fighting back.
Disconnect the negative battery cable before installation. Follow the factory service procedure for component removal, fastener torque and electrical-terminal positioning.
Final Verdict
The A-Premium 17986 is a broad GM-platform replacement starter covering selected 2006–2020 vehicles with 3.0L and 3.6L V6 engines. Its principal specifications are 12 volts, 1.4 kW, clockwise rotation and a 12-tooth pinion.
Confirm the VIN, engine and OE number before purchase, paying particular attention to the Cadillac XTS, 2017 GMC Acadia and models offered with multiple engine families.
