Accessory Drive Belt Guide for the 1989-1994 Dodge B250
Keep your classic Dodge van running by understanding its accessory drive belt system and knowing when to replace the belts.
- Visually confirm if your van uses multiple V-belts or a single serpentine belt before buying parts, as it varies by year and engine.
- It is best practice to replace all belts at the same time if you have a multi-belt system.
- High-quality aftermarket brands like Gates, Continental, and Dayco offer excellent reliability and are often superior to the original 30-year-old belt technology.
- Proper tension is critical. A belt that is too loose will slip and squeal, while a belt that is too tight can cause premature wear on accessory bearings.
Understanding Your Van's Belt System
The 1989-1994 Dodge B250 can have a couple of different accessory drive setups depending on the year, engine (3.9L V6, 5.2L V8, 5.9L V8), and options like air conditioning. Early models in this range primarily use a system of multiple, individual V-belts. Later models, particularly from 1992 onwards, may feature a single, flat, ribbed serpentine belt. It is crucial to visually inspect your engine to determine which system you have before ordering parts. A V-belt system will have several individual, V-shaped belts, while a serpentine system has one wide, flat belt that winds around all the pulleys.
Choosing the Right Aftermarket Belts
For a vehicle of this age, original equipment (OEM) belts are likely discontinued or difficult to find. The good news is that aftermarket belt technology has advanced significantly, and reputable brands offer high-quality replacements that often exceed the original specifications. When shopping for new belts, you can generally categorize brands into tiers based on quality and reputation among mechanics.
- Premium Brands (Gates, Continental): Gates is a highly respected name in the industry, known for durability and often considered an OEM-quality supplier. Continental is another top-tier brand, also with a strong reputation for making quality rubber products that meet or exceed OEM standards.
- OEM-Quality & Standard Brands (Dayco, Bando): Dayco and Bando are major manufacturers that supply belts to many car companies. They are known for producing reliable and durable belts that provide excellent performance and longevity. Many mechanics use these brands regularly with confidence.
- Value Brands (ACDelco, Store Brands): While ACDelco is GM's official parts brand, their belts for other makes are generally considered a standard, reliable option. Many store brands offer a budget-friendly choice that can be suitable for a vehicle that sees limited use, but may not have the same longevity as premium brands.
A Note on Belt Noise
Squealing is a common sign of a worn or loose belt. However, noise can also be caused by issues with pulley alignment, a weak tensioner (on serpentine systems), or worn bearings in an accessory. If a new belt doesn't solve a noise problem, these other components should be inspected.
Aftermarket vs. OEM Quality
For a 1989-1994 B250, high-quality aftermarket belts from brands like Gates, Continental, or Dayco are an excellent choice. The rubber compounds (like EPDM) used in modern belts are more resistant to heat, oil, and cracking than the materials used in the original belts from the 1980s and 90s. You can be confident that a new aftermarket belt from a reputable manufacturer will provide reliable service.
Known Issues, Recalls, and TSBs
No recalls or specific Technical Service Bulletins (TSBs) related to accessory drive belts were found for the 1989-1994 Dodge B250 during a search of the NHTSA database and other resources. One general TSB from 1991 mentioned fan belt chirp caused by excess paint on the water pump pulley, with the fix being to clean the pulley. The most common issues reported by owners are typical for any vehicle of this age: belts wearing out, cracking, and causing noise.

Frequently Asked Questions
How do I know if my B250 has V-belts or a serpentine belt?
You must look at the front of your engine. If you see multiple, separate rubber belts connecting different pulleys, you have a V-belt system. If you see one single, wide, flat belt snaking around all the pulleys, you have a serpentine belt system. 🎬 Watch this video for serpentine belt solutions on a 1991 B250. This can vary by year and engine options.
Should I replace all the belts at once?
Yes. If you have a V-belt system, it is highly recommended to replace all the belts at the same time. They have all been exposed to the same conditions and age. Since you often have to remove outer belts to get to inner ones, replacing them all at once saves you from having to do the job again soon.
What tools are needed to change the belts?
For a V-belt system, you'll typically need a basic set of wrenches or a socket set. Tension is adjusted by loosening the mounting bolts of an accessory (like the alternator), moving it to create slack, and then retightening it after the new belt is on. A serpentine system usually has a spring-loaded tensioner that requires a wrench or breaker bar to release the tension.
How tight should the new belts be?
For V-belts, a common rule of thumb is that you should be able to twist the belt about a quarter turn (90 degrees) at its longest span, and it should have about a half-inch of deflection when you press on it firmly. Over-tightening can damage the bearings in your accessories, while being too loose will cause slipping and squealing.

Technical Specifications
The key specifications are the belt type (V-belt or Serpentine), length, and width/rib count. These vary significantly based on the engine (3.9L, 5.2L, 5.9L) and installed accessories (with or without A/C, alternator amperage). Always match the new belt to the old one or use a parts catalog for your specific configuration.
