Accessory Drive Belts for the 1987 GMC V1500: A Complete Guide
Keep your classic GMC's accessories running smoothly by choosing the right replacement belts.
- Your 1987 V1500 uses multiple V-belts, not a single serpentine belt; you must buy the correct belt for each specific accessory.
- Squealing noises and visible cracks are clear signs that your belts need immediate replacement to avoid a breakdown.
- Reputable aftermarket brands like Gates, Continental, and Dayco offer excellent quality and are preferred by many owners and mechanics.
- When one belt fails, it is best practice to replace all of them at the same time and inspect the pulleys for wear.
Understanding Your V1500's Belt System
The 1987 GMC V1500 uses a multiple V-belt system, not a single serpentine belt found in newer trucks. This means you have separate belts for different accessories. Depending on your specific engine (like the 5.0L V8, 5.7L V8, or 6.2L V8) and options like air conditioning, you could have two, three, or even four separate belts. It's critical to identify which specific belt has failed or needs replacement, as they come in different lengths and styles. A visual inspection is the best way to determine your truck's specific configuration.
Signs of a Failing Accessory Belt
Worn-out belts give clear warning signs. Ignoring them can leave you stranded.
- Squealing Noises: A high-pitched squeal, especially when starting the engine or accelerating, is the most common symptom. This means the belt is slipping on the pulleys because it's old, worn, or loose.
- Visible Damage: Look for cracks, fraying, glazing (a shiny surface), or missing chunks on the belts. Any visible damage means the belt's integrity is compromised and it should be replaced.
- Accessory Malfunctions: If your power steering becomes heavy, the battery light comes on, the engine temperature rises, or the A/C stops blowing cold, a failed belt is a likely cause. Each of these systems relies on a belt to function.
Critical Failures
A broken belt driving the water pump will cause the engine to overheat quickly, leading to severe engine damage. A failed alternator belt will leave you with a dead battery and a truck that won't start.
Choosing the Right Aftermarket Belts
For a vehicle like the 1987 V1500, aftermarket belts offer excellent quality, often meeting or exceeding original equipment (OE) specifications. There is no significant advantage to sourcing a genuine GM belt, which may be difficult to find. The key is to choose a reputable brand.
Brand Tiers
- Premium Brands (Gates, Continental): Gates is a highly respected and frequently recommended brand in forums for its quality and durability. Many professional mechanics prefer Gates belts. Continental (which now includes the former Goodyear Gatorback line) is also considered a top-tier choice, known for reliability.
- Quality Mid-Range (Dayco, Bando): Dayco is a well-known brand that offers reliable performance and is often praised by truck owners. Some users note they can be stiffer than other brands when new. Bando is another solid choice often mentioned as a quality alternative.
Pro Tip: Many store brands, like NAPA, are manufactured by Gates, offering the same quality under a different name. When replacing belts, it's a good practice to replace them all at once, especially if they appear to be the same age. Also, inspect the pulleys for wobble or noise, as a bad pulley can destroy a new belt quickly.

Frequently Asked Questions
Do I need a serpentine belt or V-belts?
Your 1987 GMC V1500 uses a multiple V-belt setup. You will need to buy individual belts for each component (or a set of them), not a single serpentine belt.
Should I replace all the belts at the same time?
Yes, it is highly recommended. If one belt is old and worn, the others are likely in similar condition. Replacing them all at once saves you from future breakdowns and repeated labor costs.
What are cogged V-belts?
You may see "cogged" or "raw edge" belts available. These belts have notches on the underside, which allows them to bend more easily around smaller pulleys and can help them run cooler, potentially increasing their lifespan. They are a good upgrade for your truck.
Are there any recalls for my truck's belts?
No recalls were found for accessory drive belts on the 1987 GMC V1500. While some TSBs exist for newer GM trucks regarding belt tensioners and alignment, they do not apply to this specific model year.
