A Practical Guide to the 1959 Studebaker 4E12D Starter Solenoid
Everything you need to know about diagnosing and replacing the starter solenoid on your classic Studebaker truck.
- The most common symptom of failure is a single loud 'click' with no engine crank.
- The solenoid on your 1959 4E12D is a remote unit, located on the inner fender or firewall, not on the starter itself.
- Replacement is a simple DIY task that requires basic tools and less than an hour.
- Standard Ignition is the primary aftermarket brand available, offering a reliable replacement part.
Is Your Studebaker's Starter Solenoid Failing?
A bad starter solenoid can leave you stranded. Because the 1959 Studebaker 4E12D has a simple electrical system, the signs of failure are usually clear. Pay attention to these symptoms to know if your solenoid is the source of your starting problems.
Top 4 Signs of a Bad Starter Solenoid
- Loud Single Click: You turn the key and hear one loud "CLICK" from under the hood, but the engine doesn't crank. This is the most common sign. It means the solenoid is receiving power from the ignition but is failing to send the high-current power to the starter motor.
- No Sound at All: You turn the key and get complete silence. If your battery is good and the headlights work, the solenoid may have failed completely and isn't even trying to engage.
- Intermittent Starting: Your truck starts fine one day but won't start the next. This on-again, off-again behavior often points to worn internal contacts inside the solenoid that only make a connection sometimes. This problem will eventually lead to a complete failure.
- Starter Keeps Running: In rare cases, the solenoid's internal switch can get stuck in the "on" position. This will cause the starter motor to continue running even after the engine has started and you've released the key. This is a serious issue that can quickly burn out your starter motor.
Don't Confuse a Bad Solenoid with a Bad Battery
A rapid, machine-gun-like clicking sound when you turn the key is usually a sign of a weak or dead battery, not a bad solenoid. Always check that your battery is fully charged and the terminals are clean and tight before replacing the solenoid.
Choosing a New Aftermarket Solenoid
For a classic truck like the 1959 Studebaker 4E12D, finding "new OEM" parts is not an option. Your choices are a modern aftermarket part, a New Old Stock (NOS) part, or a used original part. For a component like a solenoid, a new aftermarket part is often the most reliable and cost-effective choice.
Available Brand: Standard Ignition
Currently, Standard Ignition (also known as Standard Motor Products or SMP) is the primary brand manufacturing new aftermarket starter solenoids for your truck. Standard is a well-known company that has been making replacement parts for over 100 years. Their solenoids are built with heavy-duty copper contacts and windings to help them last longer and handle the high electrical current required to start your engine. For a vehicle of this era, a new Standard part is a solid choice for reliability.
Estimated Replacement Costs
The cost to replace the starter solenoid is reasonable, especially if you can do the work yourself. The part itself is not expensive, and the job is straightforward.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $49.14 |
| Shop Labor | $60 - $120 |
| Total Estimated Cost | $109 - $169 |

Pro Tip: Clean Your Connections
When you replace your solenoid, take a few extra minutes to clean the wire terminals and mounting points with a wire brush. On a classic truck, corrosion on these connections can cause resistance and lead to starting problems that mimic a bad solenoid. A clean, tight connection ensures the new part works perfectly.
Frequently Asked Questions (FAQ)
Where is the starter solenoid located on my 1959 Studebaker 4E12D?
Unlike modern vehicles, the solenoid on your truck is not attached to the starter motor. It is a remote-mounted solenoid, typically found bolted to the inner fender apron or the firewall on the passenger side of the engine bay.
Can I replace the starter solenoid myself?
Yes, this is a very DIY-friendly job for most owners. The process involves disconnecting the battery, removing a few nuts to detach the wires, and unbolting the solenoid from the fender or firewall. The job requires basic hand tools and should take less than an hour.
Are there any recalls for the starter solenoid on a 1959 Studebaker?
No, there are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA for this part on a 1959 Studebaker truck. This is normal for a vehicle of this age.
Do I need a special solenoid for my Studebaker?
Yes, you need the correct remote-mounted solenoid. The aftermarket Standard Ignition part is designed to be a direct replacement for the original. A common Studebaker part number for this solenoid was 1539716, which was used on 1959-1964 trucks.
