Accessory Drive Belt Guide for the 1959 Studebaker 4E12 Truck
Keep your classic Studebaker's engine running cool and charging properly with the right V-belts.
- Your 1959 Studebaker 4E12 uses one or more V-belts, not a modern serpentine belt.
- A broken belt will cause the engine to overheat and the battery to stop charging, leaving you stranded.
- Modern aftermarket brands like Gates and Continental are reliable and superior to original 1950s rubber.
- Checking belt tension after installation is critical; too tight damages bearings, too loose causes slipping.
Understanding the V-Belts on Your Studebaker Truck
The accessory drive system on the 1959 Studebaker 4E12 is a straightforward mechanical setup. It uses V-belts, which have a V-shaped cross-section, to grip pulleys and transfer power. These belts are responsible for spinning the generator to provide electricity and the water pump to prevent the engine from overheating. Because of their critical role, it's important to inspect them regularly and replace them at the first sign of wear.
Symptoms of a Failing Drive Belt
A worn or failing V-belt will usually provide clear warning signs. Ignoring them can leave you stranded with an overheated engine or a dead battery.
- Squealing Noises: A high-pitched squeal, especially when you start the engine or accelerate, is a classic sign of a belt that is loose or has a glazed, hardened surface.
- Visible Damage: A visual inspection is the best diagnostic tool. Look for cracks, fraying, missing chunks, or a shiny surface on the sides of the belt. Any of these mean it's time for a replacement.
- Battery or 'GEN' Light: If the generator light on your dashboard flickers or stays on, the belt driving the generator may be slipping or broken.
- Engine Overheating: If you notice the temperature gauge climbing higher than normal, the belt driving the water pump could be failing. This is a critical symptom.
Choosing the Right Aftermarket Belt
Original, new-old-stock (NOS) Studebaker belts are collector's items and not practical for a vehicle you intend to drive, as decades-old rubber is not reliable. Modern aftermarket belts are made from advanced rubber compounds like EPDM that far exceed the durability and heat resistance of the original parts.
For your 1959 4E12, reputable brands like Gates and Continental are excellent choices. Both are well-regarded in the classic car community for their quality and reliability. The most critical factor is not the brand, but ensuring you purchase the correct size—specifically the length and width—for your truck's engine and accessory configuration (e.g., with or without A/C). Always check the part number against a reliable catalog or measure your old belt if you are unsure.

Frequently Asked Questions (FAQ)
How many belts does my 1959 Studebaker truck have?
It depends on the options. A base model will have at least one belt for the generator and water pump. Models with factory options like air conditioning would have additional belts. Some part listings suggest that two belts may be required for some jobs.
Is a V-belt the same as a serpentine belt?
No. Your Studebaker uses older V-belt technology, where one or more individual belts are used. Serpentine belts are a newer design; they are wide, flat, and multi-grooved, and a single belt typically runs all the accessories.
How do I get the right tension on the new belt?
Proper tension is crucial. If it's too loose, it will slip and squeal. If it's too tight, it will cause premature wear on the bearings of your generator and water pump. A common rule of thumb for V-belts is that at the longest point between pulleys, you should be able to twist the belt about 90 degrees (a quarter turn) with your fingers.
Are there any recalls for the 1959 Studebaker 4E12 drive belt?
No. There are no active or historical recalls from the NHTSA for accessory drive belts on this vehicle. Any service bulletins or factory communications would have been issued decades ago.
Technical Specifications
The system uses one or more V-belts. Key specifications are the belt's top width and outside circumference, which must be matched to the vehicle's specific engine and accessory configuration.
