Accessory Drive Belt Guide for the 1963-1964 Studebaker 8E12
Keep your classic Studebaker truck's essential components running with the right V-belt.
- Modern aftermarket belts from brands like Gates, Dayco, and Continental are superior to original or NOS parts.
- A broken belt will immediately cause the truck to stop charging the battery and start overheating, so do not drive with a failing belt.
- Squealing is the most common symptom of a worn or loose belt, but can also indicate contaminated or misaligned pulleys.
- Replacement is a simple and inexpensive job that is very feasible for a DIY mechanic with basic tools.
Signs of a Failing Accessory Drive Belt
A worn or failing V-belt on your Studebaker truck will provide clear warning signs. Ignoring these symptoms can lead to a breakdown, as the belt powers critical systems. Look and listen for these indicators:
🎬 Watch this video to identify common bad belt symptoms.- Squealing Noises: A high-pitched squeal, especially when you start the engine or accelerate, is the most common sign of a loose or worn belt. This noise is caused by the belt slipping on the pulleys.
- Visible Wear and Damage: Inspect the belt regularly. 🎬 See how to properly inspect your belts and pulleys. Look for cracks, fraying, glazing (a shiny, hardened surface), or pieces of rubber missing. Old rubber becomes brittle with heat and age and will eventually fail.
- "GEN" Light on Dash: If the generator warning light on your dashboard flickers or stays on, the belt may be slipping. This prevents it from spinning the generator fast enough to charge the battery.
- Engine Overheating: A broken or badly slipping belt will not turn the water pump correctly. This will cause the engine to overheat quickly, which can lead to severe engine damage.
Choosing the Right Aftermarket Belt
Original Studebaker-branded belts are a thing of the past. While you might find a "New Old Stock" (NOS) belt, a rubber part that has been sitting on a shelf for decades is not reliable due to age-related degradation. Modern aftermarket belts are the best choice for your classic truck. They are made from advanced EPDM rubber compounds that resist heat, oil, and cracking far better than the original materials.
For your Studebaker 8E12, reputable brands like Gates, Dayco, and Continental are all excellent options that meet or exceed original factory specifications. Many classic truck owners and mechanics have positive experiences with these brands, often citing Gates as a top preference.
Pro Tip: Check Your Accessories
The correct belt length for your truck depends on the accessories it has (e.g., with or without A/C). Always verify the required belt size for your specific configuration before purchasing to avoid installation problems.

Frequently Asked Questions (FAQ)
How often should I replace the drive belt on my Studebaker?
For a classic vehicle, it's best to inspect the belt at every oil change and plan for replacement based on condition rather than a strict mileage interval. Look for cracks, glazing, and other signs of wear. Even if the truck isn't driven often, belts degrade over time and should be replaced every 5-7 years.
Are modern cogged V-belts better than smooth ones?
Yes. Cogged or "raw edge" V-belts are designed to be more flexible and dissipate heat better than older, smooth-wrapped belts. This can lead to a longer life and more efficient power transfer, making them a good upgrade for your classic truck.
What causes a new belt to squeal?
A new belt squealing is often a sign of an underlying issue. The most common causes are improper tension (too loose or too tight), pulleys contaminated with oil or coolant, or misaligned pulleys. Using belt dressing is not recommended as it can damage the belt material.
🎬 Learn how to troubleshoot and fix persistent belt noise.Are there any recalls for the Studebaker 8E12 drive belt?
No. There are no recalls or specific Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the accessory drive belts on this vehicle. Issues are typically related to normal wear and tear due to age.
