Engine Oil Pressure Switch Guide for the 1956 Studebaker E13
Keep your classic Studebaker truck's engine safe by understanding this critical sensor.
- A faulty oil pressure switch can either fail to warn you of low oil pressure or give a false warning; always check the oil level first if the light comes on.
- For the 1956 E13, new original parts are unavailable; a new aftermarket switch from a brand like Standard Ignition is the standard, reliable replacement.
- Symptoms include a constant or flickering oil light, or an oil leak directly from the sensor.
- Replacement is a simple, low-cost DIY task that can be done in under 30 minutes with basic tools.
Is Your Oil Pressure Light Lying to You?
On a classic Studebaker V8, the oil pressure warning light is your main window into the engine's health. But what happens when the sensor sending the signal goes bad? A faulty engine oil pressure switch can give you a false sense of security or a needless scare. It might fail to warn you of dangerously low oil pressure, or it might keep the warning light on even when pressure is perfectly fine. Since this part is simple and inexpensive, it's often the first thing to check when you have oil pressure warning issues.
Symptoms of a Failing Oil Pressure Switch
A bad oil pressure switch can cause confusing symptoms. Here's what to look for:
- Oil Light Stays On: The most common symptom is an oil pressure warning light that is always on, even after you've checked the oil level and are sure the engine has good pressure.
- Flickering Oil Light: A light that flickers or comes on intermittently, especially at idle or during turns, can point to a failing switch.
- Oil Leak: The switch itself can develop a leak over time. You might see oil seeping from the sensor's body or its electrical connection.
- No Oil Light When Ignition is On: The warning light should briefly illuminate when you turn the key to the 'on' position before starting the engine. If it doesn't, the switch or the bulb could be bad, meaning it won't warn you if a real problem occurs.
Don't Ignore Oil Warnings
Never assume a warning light is just a bad sensor. If your oil pressure light comes on while driving, pull over immediately, turn off the engine, and check your oil level. Running an engine with low oil pressure can cause catastrophic damage in a very short time.
Choosing the Right Aftermarket Switch
For a 1956 Studebaker E13, finding a "New Old Stock" (NOS) original part is practically impossible. The good news is that the aftermarket provides reliable replacements. For a simple component like an oil pressure switch, a quality aftermarket part is a perfectly sound choice.
- Standard Ignition (Standard Motor Products): Standard Ignition is a well-known aftermarket brand that has been making electrical components for decades. Their parts are widely available and are considered a reliable, go-to option for classic vehicles like the Studebaker E13. Given the limited availability of parts for this truck, Standard is often the only brand available for a new switch.

DIY-Friendly Repair
Replacing the oil pressure switch is a very DIY-friendly job that most owners can do themselves. Access is generally good on these older engines.

The entire job usually takes less than 30 minutes.
Frequently Asked Questions
Where is the oil pressure switch located on my 1956 Studebaker E13?
On most classic V8 engines, including the Studebaker V8, the oil pressure switch is threaded directly into the engine block. It is typically located near the oil filter or the distributor. Look for a small, single-wire sensor screwed into the side of the block.
Is a flickering oil light always a bad switch?
Not always. While a flickering light is a common symptom of a failing switch, it can also indicate genuinely low oil pressure at idle, which could be caused by a low oil level or a worn oil pump. Always check your oil level first.
Can I replace this part myself?
Yes, this is a great job for a DIY mechanic. You will need a proper-sized deep socket or wrench, and some thread sealant for the new switch. The part is usually easy to access on the side of the engine block.
Are there any recalls for the oil pressure switch on a 1956 Studebaker E13?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls for this part on a 1956 Studebaker truck. Recalls on vehicles of this age are extremely rare.
