A Guide to Replacing the Alternator on Your 2013-2022 Jeep Cherokee
Is your battery light on or are your headlights dim? Your Cherokee's alternator might be the problem.
- Verify your engine (2.4L or 3.2L) and required amperage (160A or 180A) before ordering a new alternator.
- Symptoms include dimming lights, a battery warning on the dash, and whining noises from the engine.
- The major alternator recall (NHTSA 17V-435) was for the Grand Cherokee, not the standard Cherokee (KL model).
- Before replacing the alternator, check the main alternator fuses (F03, F04) in the under-hood fuse box.
Signs of a Failing Alternator in a Jeep Cherokee
When an alternator starts to fail, it usually gives you a few warning signs. Ignoring them can leave you stranded. Here are the most common symptoms for a 2013-2022 Jeep Cherokee:
- Dimming or Flickering Lights: You may notice your headlights and dashboard lights are dim when the Jeep is idling but get brighter as you press the gas pedal. This is a classic sign of a weak alternator that can't provide steady power.
- Battery Warning Light: A battery-shaped warning light on your instrument cluster is a direct signal that there's a problem with the charging system.
- Whining or Grinding Noises: A high-pitched whining or a grinding sound coming from the engine bay that changes with engine speed often points to worn-out bearings inside the alternator.
- Electrical Problems: Because the alternator powers everything, you might experience strange issues like power windows moving slowly, the radio cutting out, or the engine stalling unexpectedly.
- Frequently Dead Battery: If you need to jump-start your Cherokee often, the alternator is likely not recharging the battery properly. A new battery might fix the problem temporarily, but it will also die if the alternator isn't replaced.
Important Note on Recalls
There was a well-known FCA recall (NHTSA Campaign #17V435) for alternator failure that included some Jeep models. However, this recall was for the 2012-2014 Jeep Grand Cherokee, not the regular Jeep Cherokee (KL model) covered in this article. No major alternator recalls have been issued for the 2013-2022 Jeep Cherokee.
Choosing the Right Aftermarket Alternator
When shopping for a new alternator, you have options ranging from budget-friendly to premium. For a vehicle with as many electronics as the Cherokee, choosing a quality part is important for long-term reliability.
Brand Quality Tiers
- Premium Brands (Bosch, Mopar): Mopar is the original factory part and offers a guaranteed fit and performance. Bosch is a major OEM supplier known for high-quality remanufactured units that are fully load-tested to meet strict standards. These are your most reliable choices.
- Quality Aftermarket (Remy): Remy is a long-standing aftermarket brand. Forum users often have good experiences with their new units.
- Standard/Economy Brands (WAI Global, BBB Industries): WAI offers 100% new alternators, which avoids the hassle of a core charge. However, some owner reviews mention whining noises, suggesting potential quality control issues. BBB Industries is a large remanufacturer that often supplies store brands like those from NAPA, which are generally considered decent quality.
Check Your Amperage!
The most common mistake when ordering is getting the wrong amperage. Your Cherokee's engine determines the correct alternator. The 2.4L 4-cylinder engine 🎬 See a quick overview of the 2.4L alternator removal typically uses a 160 amp alternator. The 3.2L V6 engine can use either a 160 amp or a 180 amp unit. Always verify the amperage of your original part or check your vehicle's specifications before ordering.

Frequently Asked Questions
Is replacing the alternator on a Jeep Cherokee a DIY job?
For an experienced DIYer, yes. However, it is a moderately difficult job due to tight access. The process involves removing the air intake box and serpentine belt. Some mechanics also loosen the A/C compressor 🎬 Watch this 2015 Cherokee alternator replacement walkthrough to create enough room to remove the alternator. It can take a home mechanic around 2.5 to 4 hours.
🎬 Watch: Step-by-step alternator replacement for 2014-2019 modelsShould I replace the battery at the same time as the alternator?
It's a good idea to have your battery tested. A failing alternator can damage a battery by failing to charge it properly, and a weak battery can put extra strain on a new alternator. If the battery is over four years old or fails a load test, you should replace it.
What are the main fuses for the alternator?
Before assuming the alternator is bad, it's wise to check the main fuses. In the under-hood fuse box (Power Distribution Center), the primary alternator fuses are often labeled F03 and F04. A blown fuse can cause the alternator to stop charging completely.
Do I need a special high-output alternator?
For most owners, the stock 160 or 180 amp alternator is sufficient. However, if you have added significant electrical accessories like a powerful audio system with amplifiers, a winch, or extensive off-road lighting, you might consider a high-output alternator to handle the extra demand.
