- Proper belt tension is critical on a Silver Hawk to avoid slippage and prevent damage to the generator.
- Given the low cost, it's wise to replace belts proactively if their age is unknown to prevent being stranded.
Is Your Studebaker's Belt Trying to Tell You Something?
A failing accessory drive belt on your Silver Hawk will usually give you clear warning signs. Because these are simple V-belts, the symptoms are straightforward. Ignoring them can lead to a breakdown, so it's best to address them as soon as they appear.
Common Failure Symptoms:
- Squealing Noises: A high-pitched squeal, especially when you start the engine or during acceleration, is the most common sign of a slipping or worn belt. This can be caused by wear, improper tension, or contamination from oil or coolant.
- Visible Wear and Tear: Inspect your belts regularly. Look for cracks, fraying, glazing (a shiny, smooth surface), or missing chunks. Any visible damage means the belt needs to be replaced immediately.
- Dimming Lights or Charging Issues: Since the belt drives the generator, a slipping belt can cause the battery to not charge properly. You might notice the 'GEN' or 'AMP' light flickering on your dash, or your headlights may seem dim at idle.
- Engine Overheating: The belt also drives the water pump. If it slips or breaks, the coolant will stop circulating, causing the engine to overheat quickly. This is a serious condition that can cause major engine damage.
Choosing the Right Aftermarket Belt
For a classic car like the 1957-1959 Silver Hawk, finding original equipment (OEM) belts is nearly impossible. Fortunately, the aftermarket offers excellent, high-quality V-belts from reputable manufacturers. The technology for V-belts is well-established, and modern aftermarket belts are often more durable than what was available in the 1950s. You will not be sacrificing quality by choosing a good aftermarket brand.
Here’s a look at the common brands available:
- Gates: A highly respected name in the belt industry. Gates belts are known for their durability and precise fit. Many classic car owners and mechanics trust them for reliability. They are often considered a top-tier choice.
- Dayco: Another top-tier manufacturer that supplies belts to many car companies. Dayco belts are known for their quality construction and are a solid choice for your Studebaker.
- Continental (ContiTech): Continental is a massive automotive supplier, and their belts are considered OEM quality for many European brands. They offer excellent performance and are a reliable option for any classic car.
Pro Tip: For these brands, quality is very comparable. The best choice is often the one that is readily available and fits your budget. You can't go wrong with a new belt from Gates, Dayco, or Continental.

Frequently Asked Questions
How many belts does my Silver Hawk have?
A standard Silver Hawk will have one main belt for the generator and water pump. If your car is equipped with optional power steering, it will have a second, separate belt for that system.
How do I know if my belt has the right tension?
Proper tension is crucial. A loose belt will slip and squeal, while a belt that is too tight can damage the bearings in your generator or water pump. A good rule of thumb is that the belt should have about a half-inch of deflection (play) when you press on it firmly in the middle of its longest span.
Are there any recalls or known issues for Silver Hawk belts?
No. There are no official recalls or Technical Service Bulletins (TSBs) from the NHTSA related to the accessory drive belts for the 1957-1959 Studebaker Silver Hawk. Any issues you encounter will be due to normal wear and tear or improper installation.
Should I replace my belts even if they look okay?
Yes. Rubber deteriorates over time, even without use. If you don't know how old your belts are, it's cheap insurance to replace them. A snapped belt will disable your car immediately, and it's a failure you can easily prevent with proactive maintenance.
