Is Your Oil Pressure Light Lying to You?
On a classic Studebaker truck, the oil pressure warning light is a key indicator of engine health. But 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 fine. Since this part is simple and inexpensive, it's often the first thing to check when you have oil pressure warning issues.
Choosing the Right Aftermarket Switch
For a 1956 Studebaker E7, finding a "new old stock" (NOS) original part is nearly impossible. The good news is that the aftermarket provides reliable replacements. Aftermarket brands are your only practical choice.
- Standard Ignition (Standard Motor Products): Standard Ignition is a well-known aftermarket brand that has been around for decades. They manufacture a wide range of electrical components for classic vehicles. For a simple part like an oil pressure switch, their quality is generally considered reliable and is a common choice for repairs on classic trucks.

Pro Tip: Use Thread Sealant
The oil pressure switch has tapered pipe threads that seal against the engine block. When installing the new switch, apply a small amount of thread sealant or Teflon tape to the threads to prevent oil leaks. Be careful not to use too much, as you don't want it to break off and enter the engine's oil passages.
Frequently Asked Questions (FAQ)
Where is the oil pressure switch located on a 1956 Studebaker E7?
On most classic Studebaker engines, 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 an aftermarket switch reliable for my classic truck?
Yes. For a simple on/off switch like this, a quality aftermarket part from a reputable brand like Standard Ignition is a perfectly reliable and cost-effective choice. Since new original parts are not available, aftermarket is the standard for these repairs.
What happens if I ignore a bad oil pressure switch?
Ignoring a faulty switch is risky. If it's stuck "off," it won't warn you of a real low-pressure event, which could lead to catastrophic engine failure. If it's stuck "on," it creates unnecessary worry and could cause you to ignore a real problem if one develops.
Can I replace this part myself?
Yes, this is a very DIY-friendly job for most owners. Access is generally good on these older trucks, and the process simply involves disconnecting one wire, unscrewing the old switch with a wrench, and installing the new one. The entire job usually takes less than 30 minutes.
