Dodge B350 (1981-1988) Accessory Drive Belt Replacement Guide
Keep your classic Dodge van running reliably by understanding which accessory drive belts you need and how to choose the right ones.
- Your 1981-1988 B350 uses multiple V-belts, not a single serpentine belt; confirm your engine and accessories before ordering.
- It is highly recommended to replace all accessory drive belts at the same time as a set.
- Squealing noises are a primary indicator of loose or worn belts that require attention.
- Top aftermarket brands like Gates, Dayco, and Continental offer quality replacements for this vehicle.
Understanding Your B350's V-Belt System
Unlike modern vans that use one long serpentine belt, your 1981-1988 Dodge B350 uses a multiple V-belt system. This means several individual belts are responsible for powering different accessories. This setup was common for the era and requires a specific approach for maintenance and replacement. The number and length of the belts depend entirely on your van's specific engine (like the 5.2L or 5.9L V8) and what accessories it has (e.g., with or without air conditioning). This is the most common reason for ordering incorrect parts.
Signs of a Failing Accessory Drive Belt
Knowing the signs of a worn V-belt can prevent you from being stranded. Here’s what to look and listen for:
- Squealing Noises: A high-pitched squeal, especially when starting the engine or under heavy load, is the most common symptom. It's usually caused by a loose or worn belt slipping on the pulley.
- Visible Wear and Tear: Inspect your belts regularly. Look for cracks, fraying, glazing (a shiny, hardened surface), or missing chunks of rubber. Any of these signs mean the belt is old and needs immediate replacement.
- Accessory Malfunctions: If your power steering becomes heavy, the battery warning light comes on, or the engine temperature starts to climb, a belt may have snapped. A broken belt means the component it drives has lost power.
Critical Failure Warning
If the belt that drives the water pump fails, your engine will overheat very quickly, which can cause catastrophic engine damage. If you see the temperature gauge rise suddenly, pull over and shut off the engine immediately.
Choosing the Right Aftermarket Belts
For a vehicle of this age, new OEM belts are virtually nonexistent. However, top-tier aftermarket brands offer excellent quality that often meets or exceeds the original 1980s standards. The key is to buy the correct set of belts for your specific van.
Pro Tip: Before ordering, confirm your engine size (e.g., 5.2L 318ci or 5.9L 360ci V8) and which accessories your van has. It is best practice to replace all the belts at the same time, even if only one is showing signs of failure.
Brand Options: Continental, Dayco, and Gates
You have good choices when it comes to aftermarket V-belts. Continental, Dayco, and Gates are all well-regarded manufacturers that produce reliable belts for this vehicle. Forum discussions among classic truck owners show a general consensus that you can't go wrong with any of these three. Gates is often cited as a top choice, with a reputation for durability. Dayco's "Top Cog" belts are also frequently recommended for their grip and performance. Continental (which now owns the Goodyear Gatorback line) is another excellent option known for quality. Ultimately, proper installation and tensioning are just as important as the brand you choose.

Frequently Asked Questions (FAQ)
How many belts does my 1981-1988 B350 have?
It depends on the engine and accessories. Your van could have anywhere from two to five individual V-belts. You must verify the configuration for your specific vehicle; check for a belt routing diagram under the hood or consult a repair manual.
Can I replace just one bad belt?
While you can, it's not recommended. Belts wear out at a similar rate. If one has failed, the others are likely near the end of their service life. Replacing them all at once is a best practice that saves you from future breakdowns.
Is replacing the V-belts a DIY job?
Yes, for someone with mechanical experience. Unlike modern serpentine belts with automatic tensioners, you will need to manually loosen each accessory, install the new belt, and then properly tension it by prying the accessory back before tightening the mounting bolts. It requires basic hand tools and patience.
What happens if the tension is wrong?
Incorrect tension is a primary cause of belt problems. If a belt is too loose, it will slip and squeal, generating heat that leads to glazing and cracking. If it's too tight, it will put excessive strain on the bearings of the accessories (like the alternator and water pump), causing them to fail prematurely.
Technical Specifications
System uses multiple V-belts. The number, length, and width of the belts vary based on the engine (5.2L V8 or 5.9L V8) and factory-installed accessories (with or without A/C, etc.). Belts are manually tensioned by adjusting the position of the accessories.
