11252 Car Alternator for Chevrolet Traverse, GMC Acadia, Buick Enclave

In this review of the 11252 Car Alternator the bottom line is practical: it is a solid, direct-replacement alternator for owners of 3.6L V6 GM crossovers who need a reliable 170A unit without factory delay. The reviewer found the alternator to install cleanly when the correct part number and wiring checks were observed, and its adherence to OEM form and function makes it a sensible choice for mechanics or DIYers replacing a failed charging unit. The main reason to buy is straightforward compatibility combined with a full 170A output for higher accessory loads.

Key Features

• Direct replacement: Designed to match the OEM fit and mounting for a seamless swap into the original location with minimal modification.
• 170A output: Provides robust charging capacity to support modern electrical loads and help maintain battery health under demanding conditions.
• 12V and CW rotation: Matches vehicle electrical system and rotation direction so pulley and belt alignment remain correct.
• 6-groove pulley, 56mm diameter: Ensures correct belt engagement and reduces the chance of slippage on compatible drivetrains.
• Internal regulator and fan: Simplifies installation by containing control electronics and cooling inside the housing for compact packaging.
• Tested to OEM standards: Each alternator undergoes full function testing to ensure it meets expected charging performance before shipping.

Who It's For

This alternator is aimed at owners and independent repair shops working on Buick Enclave (2008-2016), Chevrolet Traverse (2009-2016), GMC Acadia (2007-2016, including Acadia Limited 2017), and Saturn Outlook (2007-2010) with the 3.6L V6 who require a direct-fit 170A replacement. It suits vehicles that need the specific OEM-compatible part numbers listed for a straight swap.

It is less suitable for vehicles outside the stated models or for customers who are unsure of their OEM part number; in those cases confirming the part number or consulting a technician is recommended before purchase to avoid fitment issues.

Pros & Cons

Frequently Asked Questions

Will this alternator fit my 3.6L Enclave or Traverse?
Confirm the OEM part number and vehicle year to ensure fit; the alternator is intended for the listed 3.6L models but exact part number matching is recommended.

Does the unit include an internal voltage regulator?
Yes, the alternator is supplied with an internal regulator and internal fan as specified.

What if the alternator does not charge after installation?
