Accessory Drive V-Belts for the 1981-1988 Dodge D350
Keep your classic Dodge D350 running strong by understanding its unique V-belt system and choosing the right replacement.
- Your D350 uses multiple V-belts, not a single serpentine belt. Identify which belt needs replacement or change them all as a set.
- Verify the exact belt length needed for your specific engine and accessory combination (A/C, no A/C, etc.) before purchasing.
- High-quality aftermarket brands like Gates and Continental are excellent choices and readily available.
- While replacing belts, inspect the pulleys for wear and ensure proper tension to prevent premature failure.
Signs of a Failing Accessory V-Belt
A worn or failing V-belt on your Dodge D350 will give you several warning signs. Ignoring them can lead to a breakdown. Look out for these symptoms:
- Squealing or Screeching Noises: This is the most common sign. You may hear a high-pitched squeal when you start the engine, accelerate, or turn the steering wheel. This noise is caused by the belt slipping on the pulleys.
- Visible Wear and Damage: Inspect the belts themselves. Look for cracks, fraying, glazing (a shiny, smooth surface), or chunks of rubber missing. If cracks appear every 1-2 cm, the belt is at the end of its life.
- Component Issues: A slipping belt can't properly power the accessories. You might notice dimming headlights (alternator belt), difficulty steering (power steering belt), or your engine temperature climbing higher than normal (water pump belt).
V-Belts, Not a Serpentine Belt
It is critical to understand that these trucks do not use a single, flat, ribbed serpentine belt. They use a set of individual V-belts. You will need to identify which specific belt has failed or, ideally, replace all of them as a set for maximum reliability. The exact number and size of belts depend on your truck's engine (e.g., 318 V8, 360 V8) and what accessories it has (like A/C or an air pump).
Choosing the Right Aftermarket V-Belts
For a vehicle from this era, new OEM Mopar belts are generally unavailable. The good news is that top-tier aftermarket brands offer excellent quality, often exceeding the original specifications thanks to modern materials like EPDM rubber.
Brand Quality Tiers
When choosing a replacement, consider these brands known for their reliability:
- Premium Quality (Gates, Continental): Both Gates and Continental (also known as ContiTech) are widely regarded by mechanics as OEM-quality or better. They are known for durability and quiet operation. Gates is a long-standing, trusted name, while Continental is also a top supplier that produces high-quality rubber components. You cannot go wrong with either brand.
- Standard Quality (Dayco): Dayco is a well-known brand that produces reliable belts and is widely available. While some users report they can be slightly noisier or stiffer than premium brands, they are a solid and affordable choice for any D350 owner.
Pro Tip: Check Your Pulleys
The leading cause of repeated belt failure is not the belt itself, but issues with the system. Before installing a new belt, check the pulleys for any wobble, roughness when spun, or damage. Also, ensure they are properly aligned. Proper belt tension is also critical for a long service life.

Frequently Asked Questions
How many belts does my Dodge D350 have?
The exact number depends on your engine and factory-installed options. Most V8 models will have at least three to four separate V-belts for the alternator, power steering, water pump/fan, and A/C compressor. It is essential to visually inspect your engine bay to confirm the configuration before ordering.
What is the most common mistake when ordering?
The most common mistake is ordering the wrong size belt. Because of the different engine and accessory combinations, many different belt lengths were used. Always verify the required belt length by checking the part number on the old belt or by carefully measuring it if the number is unreadable. When in doubt, use a parts catalog specific to your truck's VIN or engine/accessory setup.
Can I replace the V-belts myself?
Yes, this is a very DIY-friendly job for a home mechanic. Unlike modern systems with complex tensioners, V-belt tension is usually adjusted by loosening a bolt on the accessory (like the alternator), moving it to release tension, swapping the belt, and then prying it back to apply tension before tightening the bolt.
Are there any recalls for the drive belts on these trucks?
No, there are no specific recalls or technical service bulletins (TSBs) from the NHTSA related to the accessory drive belts for the 1981-1988 Dodge D350.
