Guide to the 1958 Studebaker 3E7 Starter Solenoid
Everything you need to know about keeping your classic Studebaker truck starting reliably.
- The starter solenoid on a 1958 Studebaker 3E7 is a separate 12-volt relay, not part of the starter itself.
- Common failure symptoms include a single click, no response, or intermittent starting.
- A new aftermarket solenoid from a brand like Standard Ignition is the most practical replacement option.
- Replacement is a simple DIY task for most owners, requiring basic tools and less than an hour.
Is Your Studebaker 3E7 Having Trouble Starting?
A failing starter solenoid is a common reason for starting issues in vintage trucks like the 1958 Studebaker 3E7. Due to its age and function, this part handles a lot of electrical current and can wear out over time. Heat from the engine can also contribute to its failure. Recognizing the signs of a bad solenoid can save you from being stranded.
Symptoms of a Failing Starter Solenoid
If the starter solenoid in your 3E7 is going bad, you'll likely notice one or more of these symptoms:
- Single Loud Click: You turn the key and hear one loud "click" from the engine bay, but the engine doesn't crank. This often means the solenoid is receiving the signal to start but isn't able to send power to the starter motor.
- No Sound at All: You turn the key and nothing happens. If your battery is good and the lights work, the solenoid may have failed completely, preventing any power from reaching the starter.
- Intermittent Starting: The truck starts fine one day but won't crank the next. This can be a sign that the internal contacts of the solenoid are worn and only making a connection sometimes.
- Slow Engine Cranking: If the battery and cables are in good condition, slow cranking can be caused by a solenoid with burned internal contacts that create resistance, preventing full power from reaching the starter.
Choosing a New Aftermarket Solenoid
For a 1958 Studebaker 3E7, finding a New Old Stock (NOS) or original OEM starter solenoid is nearly impossible. The most practical and reliable option is a new aftermarket part. Aftermarket parts are newly manufactured by companies other than the original vehicle maker.
Pro Tip: On these classic trucks, the starter solenoid is a relatively simple, stand-alone part. Unlike modern vehicles where the solenoid is integrated into the starter, a separate solenoid is easier and cheaper to replace.
Brand Spotlight: Standard Ignition
Standard Motor Products (SMP), sold under the brand name Standard Ignition, is a well-known manufacturer of aftermarket parts for a wide range of vehicles, including classic models. Their starter solenoids are described as having heavy-duty copper contacts to reduce arcing and pure copper windings to create a strong magnetic field for reliable operation. For a vehicle like the 3E7, a quality aftermarket part from a reputable brand like Standard Ignition is a solid choice for reliability and performance.

Frequently Asked Questions (FAQ)
Can I replace the starter solenoid on my Studebaker 3E7 myself?
Yes, this is a very feasible DIY job for someone with basic mechanical skills and tools. The solenoid is usually mounted in an accessible location on the firewall or inner fender. The process involves disconnecting the battery, removing the electrical leads from the old solenoid, unbolting it, and installing the new one in the reverse order. Always disconnect the battery's negative terminal before starting any electrical work.
Is an aftermarket solenoid as good as an original for this truck?
For this application, a quality new aftermarket solenoid is often the best choice. Original parts are no longer manufactured, and any available "New Old Stock" would be decades old. A new part from a brand like Standard Ignition is made with modern materials and manufacturing processes, which can offer improved durability.
What are the most common mistakes when ordering this part?
The biggest mistake is not confirming the voltage. The 1958 Studebaker 3E7 uses a 12-volt electrical system. Ordering a 6-volt solenoid by mistake will result in quick failure. Also, verify the terminal configuration (number and type of posts) matches your original part, as there can be variations.
Are there any recalls or technical service bulletins for the 1958 Studebaker 3E7 starter solenoid?
No, there are no official recalls or Technical Service Bulletins (TSBs) on record with the National Highway Traffic Safety Administration (NHTSA) for this specific part on this vehicle. This is expected for a vehicle of this age.
