Choosing the Right Accessory Drive V-Belt for Your 1981-1988 Peterbilt 352
Your classic Peterbilt 352 uses multiple V-belts, and picking the correct one is critical for keeping your rig on the road.
- Your Peterbilt 352 has multiple V-belts; you must identify the exact belt for your engine and the specific accessory it drives.
- Squealing is a sign of a problem. Do not ignore it, as it indicates a worn belt, improper tension, or another issue that needs attention.
- Both Gates and Dayco are top-tier aftermarket brands that provide reliable performance for heavy-duty applications.
- Never use belt dressing as a permanent fix. Find and correct the root cause of any belt noise.
Signs of a Failing Accessory Drive Belt
On a heavy-duty truck like the Peterbilt 352, belt failure isn't just an inconvenience; it can shut you down. Listen and look for these common symptoms of a worn-out V-belt:
- Squealing Noises: A high-pitched squeal, especially when you start the engine cold or put a heavy load on the electrical system, is the most common sign of a loose or worn belt. This noise is caused by the belt slipping on the pulley.
- Visible Damage: Look at your belts. If you see cracks, splits, frayed edges, or chunks of rubber missing, the belt is at the end of its life and needs immediate replacement.
- Glazed or Shiny Appearance: A belt that looks shiny or glossy on its side walls has been slipping and overheating. This process, called glazing, hardens the rubber, reducing its grip and making it more likely to crack or fail.
A Note on Belt Squeal
While a loose belt is the most common cause of squealing, the noise can also be caused by worn pulley grooves, pulley misalignment, or fluid contamination from an oil or antifreeze leak. Simply tightening or replacing the belt may not solve the problem if the underlying issue isn't addressed.
Choosing the Right Aftermarket Belt
For a vehicle from this era, original Peterbilt belts are no longer available. All replacements are aftermarket parts. The good news is that reputable brands have been making heavy-duty belts for decades. Your choice will come down to quality and budget.
Brand Tiers for Your Peterbilt 352
- Premium Aftermarket (Gates, Dayco): Both Gates and Dayco are top-tier, trusted brands that have supplied belts to truck manufacturers for years. Many professional mechanics and fleet managers have a personal preference, but both offer excellent durability. Gates is often praised for its heavy-duty "Green Stripe" line, which is specifically designed for demanding truck and bus applications. You cannot go wrong choosing a correctly sized belt from either of these brands.
- Standard Aftermarket: Other brands like Goodyear and Continental also produce reliable belts that meet or exceed original specifications. While sometimes priced slightly lower, they are generally considered dependable for commercial use.
The Most Common Ordering Mistake
The biggest challenge is not choosing a brand, but choosing the correct part number. A 1981-1988 Peterbilt 352 could have been equipped with several different engines from Cummins or Caterpillar, each with different accessory layouts. This means there are dozens of possible belt sizes. You must know your truck's specific engine and which accessory the belt drives (e.g., 'Alternator Belt for Cummins NTC-350') to order the correct part. Measure your old belt if possible, or use a comprehensive parts catalog to match the belt to your exact vehicle configuration.

Frequently Asked Questions (FAQ)
Why are there so many different belts listed for my truck?
The Peterbilt 352 was offered with various engine options and accessory configurations over its production run. Each combination of engine (like a Cummins or CAT) and accessory (like a 75-amp alternator vs. a different model) requires a specific belt length and width. You must match the belt to your truck's exact setup.
Is Gates really better than Dayco for a heavy-duty truck?
Both are excellent, high-quality brands trusted by mechanics. Some users prefer Gates, particularly their heavy-duty "Green Stripe" belts, believing they offer superior durability under harsh conditions. However, Dayco has been an OEM supplier for over a century and produces millions of reliable belts. The most important factor is getting the correct size and tensioning it properly.
Can I use belt dressing to stop the squealing?
No. Belt dressing is a temporary fix that can actually damage your belt in the long run. It contaminates the rubber and can mask a more serious problem like a worn tensioner, bad pulley, or incorrect belt tension. The proper solution is to find and fix the root cause of the noise.
Were there any recalls for the drive belts on the Peterbilt 352?
No recalls or specific Technical Service Bulletins (TSBs) related to the accessory drive belts for the 1981-1988 Peterbilt 352 were found in a search of the National Highway Traffic Safety Administration (NHTSA) database. Any issues would be related to general wear and tear, which is expected for a vehicle of this age.
Technical Specifications
System uses multiple V-belts, not a single serpentine belt. Belt specifications (length, width, V-angle) are highly dependent on the specific engine (e.g., Cummins, Caterpillar) and accessory (e.g., alternator, A/C, fan) combination. Verification against a parts catalog using vehicle specifics is required.
