Chrysler Town & Country Alternator Guide (1990-2000)
Keep your minivan's electrical system healthy by choosing the right replacement alternator.
- Symptoms like dimming lights, a battery warning light, and a weak battery are the most common signs of failure.
- For this generation, a new aftermarket alternator from a reputable brand like Bosch or Remy offers the best value and reliability.
- Replacement is a moderately difficult DIY job; getting clearance by removing the EGR valve is a key step.
- Always check the battery's health and connections first, and plan to replace the serpentine belt along with the alternator.
Is Your Town & Country's Alternator Failing?
An alternator doesn't usually fail without warning. For the 1990-2000 Town & Country, the signs are classic symptoms of a weak charging system. You're not looking for complex computer errors, but basic electrical problems.
Common Symptoms:
- Dimming or Flickering Lights: Headlights and dashboard lights may dim, especially at idle, and then brighten as you accelerate. This is a tell-tale sign the alternator can't keep up with the electrical demand.
- "ALT" or Battery Warning Light: A light shaped like a battery on your dash indicates a problem with the charging system. This means the alternator's output has dropped below the required level.
- Slow or Dead Battery: If you find yourself with a dead battery, especially if the battery is relatively new, a weak alternator is a likely culprit. It's not providing enough power to recharge the battery after starting the engine.
- Whining or Grinding Noises: Unusual sounds from the engine bay can point to failing bearings inside the alternator.
- Electrical Gremlins: Power windows that are slow, a radio that cuts out, or other strange electrical issues can happen when the alternator can't supply consistent power.
Pro Tip: Check the Battery First
Before you replace the alternator, make sure your battery is healthy. Most auto parts stores can test your battery and alternator for free. A bad battery can sometimes mimic alternator problems. Also, inspect the battery cables for corrosion and ensure they are tight.
Choosing a New Aftermarket Alternator
For a vehicle from this era, a new aftermarket alternator is a perfectly reliable and cost-effective choice. The original Mopar parts are often remanufactured by this point anyway, and top-tier aftermarket brands produce quality new units that meet or exceed original specifications. The key is to choose a reputable brand.
Brand Quality Tiers
Not all aftermarket brands are created equal. Here’s a breakdown of common brands available for your Town & Country:
- Premium Brands (Bosch, Remy): These companies are often original equipment (OEM) suppliers for many automakers and have a long-standing reputation for quality and durability. A new alternator from Bosch or Remy is a solid investment for reliability.
- Standard Quality Brands (WAI Global, BBB Industries): These brands offer a good balance of price and performance. WAI Global is a large manufacturer, and their parts are generally considered a solid value. However, some forum users have reported occasional durability issues or whining noises with WAI units.
- Economy Brands: While the lowest price can be tempting, unbranded or store-brand economy alternators can be a gamble. They may have a shorter lifespan or inconsistent performance. Given the labor involved in a replacement, spending a little more for a brand with a known track record is often worth it.
Known Issues, Recalls, and TSBs
Searches for the 1990-2000 model years did not reveal any specific recalls or Technical Service Bulletins (TSBs) directly related to alternator failure. Major alternator recalls issued by Chrysler (NHTSA 17V-435, 14V-634) affect much newer models (2011-2014) and do not apply to this generation. The most common issues are simply age-related wear and tear on the internal components like bearings and brushes.
Cost of Replacing a Town & Country Alternator
The cost can vary based on the part you choose and who does the work. The job is manageable for a DIYer with moderate experience.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Alternator | $110 - $450 |
| Shop Labor | $150 - $300 |
| Total Estimated Cost | $260 - $750 |
Frequently Asked Questions
What amperage alternator do I need?
For the 1990-2000 Town & Country, alternators were commonly available in 120A to 140A ratings, with some higher-output options available. Unless you have added significant electrical accessories like a powerful sound system, a standard replacement matching the original amperage is sufficient. Your specific model and engine (3.3L or 3.8L) will determine the correct fit. Always verify the fitment for your exact year and engine.
Is it hard to replace the alternator on a 1990-2000 Town & Country?
The difficulty is moderate. Access can be tight, especially on the 1996-2000 models. The process involves disconnecting the battery, releasing the serpentine belt tension, removing the EGR valve for clearance, and then unbolting the alternator. It typically requires a good socket set, wrenches, and a belt tensioner tool or breaker bar. Some owners find it easier to access the belt tensioner from underneath the vehicle.
Should I buy a new or remanufactured alternator?
For this vehicle, a new unit from a quality brand like Bosch, Remy, or WAI is often the best choice. They come with all new components and a warranty. While a remanufactured unit from a top brand can be good, the quality can sometimes be inconsistent. Given the relatively small price difference, new is often the safer bet.
Do I need to replace the serpentine belt at the same time?
It's highly recommended. The belt has to be removed to replace the alternator, so you'll save on future labor by installing a new belt at the same time. Inspect the belt for cracks, fraying, or glazing. If it's not new, replace it.
