Is Your Studebaker's Oil Pressure Switch Failing?
For a classic vehicle like the 1964 Studebaker Challenger, with its robust V8 engine, maintaining oil pressure is everything. The oil pressure switch is the engine's first line of defense. Because these switches operate under pressure and heat, they can wear out over time. Ignoring a faulty switch means you could be unaware of a genuine low-oil-pressure event until it's too late.
Symptoms of a Bad Oil Pressure Switch
A failing oil pressure switch can be deceptive. It might fail in the 'on' position, the 'off' position, or leak. Look for these common signs:
- Oil Pressure Light Stays On: If the oil light on your dash remains illuminated even when the engine is running smoothly and the oil level is correct, the switch may be stuck.
- Oil Pressure Light Never Comes On: The oil light should briefly illuminate when you turn the key before starting the engine. If it doesn't, the bulb could be out, or the switch may have failed in the open position.
- Flickering Oil Light: A light that flickers randomly, especially at idle or when the engine is warm, often points to a faulty switch rather than an actual oil pressure problem, but it must be investigated immediately.
- Visible Oil Leak: The switch itself can develop leaks. You may see oil seeping from the switch's body or its electrical connector.
Choosing the Right Aftermarket Part
For a 1964 vehicle, finding New Old Stock (NOS) OEM parts is extremely difficult and often expensive. New aftermarket parts are the most practical and reliable choice for keeping your Studebaker on the road.
Standard Ignition is a well-established brand that produces quality replacement components that meet or exceed original equipment specifications. For the 1964 Challenger, the Standard Ignition PS64 is the commonly available and trusted replacement part. It is designed to provide the same fit and function as the original factory switch.

| New OEM (NOS) | Varies Greatly (if found) |
| New Aftermarket (Standard Ignition) | $12.56 - $16.58 |
| Used OEM | Not Recommended |

Known Issues, Recalls, or TSBs
As of early 2026, there are no active recalls or technical service bulletins (TSBs) issued by the National Highway Traffic Safety Administration (NHTSA) for the engine oil pressure switch on the 1964 Studebaker Challenger. This is common for a vehicle of this age, as official records are sparse.
Frequently Asked Questions
Where is the oil pressure switch located on a 1964 Studebaker?
On most Studebaker V8 engines of this era, the oil pressure switch is threaded into the side of the engine block, typically near the oil filter for easy access.
Is it a switch or a sensor?
For this vehicle, it is a simple pressure switch. It provides a simple on/off signal to the dashboard warning light. It does not provide a variable pressure reading to a gauge unless it is specifically a sending unit for a gauge.
Can I replace the oil pressure switch myself?
Yes, this is considered an easy DIY repair. You will need a basic socket set, possibly a special socket for the switch, and thread sealant. The job typically takes less than half an hour.
Do I need to drain the engine oil to replace the switch?
No, you do not need to drain the oil. A very small amount of oil may drip out when you remove the old switch, so have a rag ready. The switch is located above the oil level in the pan.
