Choosing a New Aftermarket Alternator for Your 2013-2017 Chevrolet Express 2500
Keep your workhorse van powered and on the road by understanding your alternator replacement options.
- Verify the correct amperage for your van before purchasing; check the RPO code or the old part.
- Symptoms include dimming lights, a battery warning light on the dash, and whining noises from the engine.
- Replacing the serpentine belt at the same time as the alternator is a smart, preventative measure.
- For reliability, choose premium aftermarket brands like ACDelco or Remy, which are close to original equipment quality.
Is Your Express Van's Alternator Failing?
A failing alternator can leave you stranded. Recognizing the early warning signs is key to avoiding a breakdown. Because the Express 2500 is a work vehicle, downtime is costly. Pay close attention to these symptoms to catch a problem before it becomes critical.

When replacing the alternator on your Express 2500, you have several aftermarket options. Not all brands are created equal, and the right choice depends on your budget and how you use your van.
Premium Aftermarket (Closest to OEM):
- ACDelco: As the original equipment manufacturer for GM, ACDelco is the benchmark for quality. Their new and remanufactured alternators are designed to meet GM's exact specifications. While some parts are now made overseas, they are still considered a top-tier choice for fit and reliability.
- Remy: Historically linked with Delco, Remy is a well-known brand in the aftermarket. They offer both new and remanufactured units that are generally considered a solid alternative to OEM.
Mid-Grade & Value Options:
- BBB Industries: This company produces a large volume of remanufactured alternators for many store brands. Quality can be consistent, and they are a major supplier for stores like NAPA and AutoZone. However, some user forums report mixed experiences with longevity.
- WAI Global: WAI is another major manufacturer of new aftermarket electrical parts. They are often priced competitively, but some forum discussions suggest being cautious about quality compared to premium brands.
- MPA (Motorcar Parts of America): MPA is a large remanufacturer, and like BBB, supplies many private-label brands. Quality is generally considered acceptable for the price point.
Chevrolet Express vans were equipped with several different alternators with varying amperage ratings (e.g., 105A, 145A, 150A, 220A). It is critical to match the amperage of your new alternator to the original unit or upgrade if you have added electrical accessories. Check your van's RPO code (look for codes like K68 for 105A) or the tag on the old alternator to confirm the correct output. 🎬 See how to test your battery and replace the alternator.

Frequently Asked Questions
How hard is it to replace the alternator myself?
For a DIYer with the right tools, this is a manageable job. The alternator is located at the top front of the engine and is relatively easy to access. The process involves disconnecting the battery, releasing the serpentine belt tension, removing a few bolts and electrical connectors, and swapping the unit. It typically takes 1-2 hours.
🎬 Follow this step-by-step guide to replace your Express van's alternator.What else should I replace with the alternator?
It is highly recommended to replace the serpentine belt at the same time. The belt has to be removed anyway, and a new belt ensures the new alternator is driven properly. Also, inspect the belt tensioner and idler pulleys for wear.
Are there any recalls for this alternator?
There was a recall for some 2010 model year Express vans due to an alternator defect that could cause a fire, but this does not apply to the 2013-2017 year range. Always check your specific VIN with the NHTSA for any open recalls.
Do I need a high-output alternator?
You only need a high-output alternator (e.g., 220A, 320A) if you have added significant electrical loads to your van, such as powerful audio systems, inverters, or extensive auxiliary lighting. For a stock vehicle, the factory-specified amperage is sufficient.
