Accessory Drive Belt Replacement Guide for the 1962 Studebaker 7E5
Keep your classic Studebaker truck running cool and charging properly by understanding its simple V-belt system.
- Your 1962 7E5 uses a V-belt system, not a modern serpentine belt; it may have more than one belt depending on accessories.
- Modern aftermarket belts from brands like Gates or Continental are superior in quality and durability to any original or New Old Stock (NOS) parts.
- The most common mistake is ordering the wrong size. Verify the correct belt length for your truck's specific engine and accessory configuration before buying.
- Replacement is a simple, low-cost DIY job for most owners with basic hand tools.
Signs of a Failing Accessory Drive Belt
A worn V-belt on your Studebaker 7E5 will provide clear warning signs. Because this belt runs critical components, ignoring these symptoms can leave you stranded on the side of the road. Listen for noises and visually inspect the belt regularly.
- Squealing Noises: A high-pitched squeal is the most common symptom of a worn or loose belt. This noise is often loudest when you first start the engine or when accelerating, and it's caused by the belt slipping on the pulleys.
- Visible Wear and Cracks: A visual inspection is key. Look for cracks, fraying, missing chunks of rubber, or a shiny, smooth surface known as glazing. Old rubber becomes brittle with age and heat, leading to cracks. Any visible damage means the belt's integrity is compromised.
- Battery Warning Light: If the red "GEN" light on your dashboard flickers or stays on, the belt may be slipping. This indicates it is not spinning the generator fast enough to charge the battery.
- Engine Overheating: A slipping or broken belt will not turn the water pump effectively. This will cause the engine's temperature to rise quickly, which can lead to serious engine damage.
Choosing the Right Aftermarket Belt
For a vintage truck like the 1962 7E5, original factory belts are no longer in production. While you might find a New Old Stock (NOS) part, a modern aftermarket belt is the superior choice. Brands like Gates and Continental use advanced rubber compounds that are far more durable and resistant to heat and oil than parts made in the 1960s.
Brand Quality Comparison
| Brand | Assessment |
|---|---|
| Gates | A top-tier, reputable brand known for making high-quality, reliable belts. Many mechanics and classic car owners trust Gates for its durability. |
| Continental | Another premium brand that is often an OEM supplier for many vehicle manufacturers. Continental belts are known for their quality and longevity, making them an excellent choice. |
Pro Tip: For this application, both Gates and Continental offer excellent quality. A direct comparison of their V-belts shows very similar construction. The most important factor is ensuring you order the correct belt length for your truck's specific engine and accessory combination (e.g., with or without power steering). Always measure your old belt if you are unsure.
Known Issues, Recalls, and Bulletins
There are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA regarding accessory drive belts for the 1962 Studebaker 7E5. Issues with the belt system on these durable Studebaker V8 engines are almost always related to normal wear and tear. The most common causes of failure are incorrect belt tension (too loose or too tight), contamination from oil or coolant leaks, or simple old age.

Frequently Asked Questions (FAQ)
Is it hard to replace the accessory drive belt myself?
No, this is a very DIY-friendly job on a 1960s Studebaker truck. The process typically involves using basic hand wrenches to loosen the mounting bolts on the generator, pivoting it to release belt tension, swapping the belt, and then using a lever to apply proper tension while tightening the bolts.
Why is my new belt squealing?
A new belt that squeals is almost always a sign of another issue, not a faulty belt. The most common cause is incorrect tension; it is likely too loose. Other causes include oil or coolant on the pulleys, or the pulleys themselves being misaligned or worn.
How do I know if the belt tension is correct?
Proper tension is critical. If the belt is too tight, it can cause damage to the bearings in the generator and water pump. If it's too loose, it will slip and squeal. A common rule of thumb for V-belts is that at the longest point between two pulleys, you should be able to twist the belt about 90 degrees (a quarter turn) with your fingers.
Should I replace the belt even if it looks okay?
Yes, if you don't know how old it is. Rubber degrades over time, not just with mileage. For a classic vehicle, it's good practice to inspect the belt annually and replace it every 3-5 years as a form of preventative maintenance to avoid being stranded.
Technical Specifications
The system uses a V-belt design. Key specifications are the belt's top width and its outside circumference (length). These dimensions vary depending on the engine and accessories (generator vs. alternator, power steering, etc.), so measurement or part number cross-reference is essential.
