Keep your Studebaker's V8 engine safe by understanding and diagnosing the oil pressure warning switch.
- A faulty oil pressure switch is a common, inexpensive fix for a dashboard warning light.
- Always verify actual engine oil pressure with a mechanical gauge to rule out serious engine problems before relying on the warning light.
- New aftermarket parts from brands like Standard Ignition are the most practical and reliable replacement option for your Daytona.
- This is a simple DIY repair that most owners can complete in under 30 minutes with basic tools.
Is Your Oil Pressure Light On?
A glowing or flickering oil pressure light on your Studebaker's dash is a signal you can't ignore. While it can indicate a serious internal engine problem, it's often caused by a simple, inexpensive failed oil pressure switch. On a classic car like the 1964 Daytona, this switch is a common failure point due to age. This guide will help you understand the symptoms, choose the right part, and decide if this is a job you can tackle yourself.
Symptoms of a Failing Oil Pressure Switch
- Oil Light Stays On: The most common symptom is the oil pressure warning light remaining illuminated even when you know the engine has good oil pressure.
- Flickering Oil Light: The light may flicker, especially at idle or when the engine is hot. This can be a sign of a switch that is failing intermittently.
- Oil Light Never Comes On: If the warning light doesn't illuminate when you first turn the key to the 'On' position (before starting the engine), the switch may have failed in the open position.
- Visible Oil Leak: The switch itself can develop leaks over time. If you see oil seeping from the switch or its electrical connector, it needs to be replaced.
Choosing Your Aftermarket Replacement
For a 1964 vehicle, finding original "OEM" parts from Studebaker is not possible. You might find "New Old Stock" (NOS) parts, but these are rare, can be very expensive, and may have degraded seals from decades of storage. The most practical and reliable choice is a new aftermarket part.
Brand: Standard Ignition (Standard Motor Products)
Standard Ignition is a well-established aftermarket brand that produces replacements for classic vehicles. Their switches are designed to meet or exceed original specifications and are manufactured using modern materials and quality control processes. For the 1964 Daytona, a Standard Ignition switch is a readily available, affordable, and reliable option that serves the function perfectly.

Frequently Asked Questions (FAQ)
Where is the oil pressure switch located on the 1964 Daytona?
On the Studebaker 289 V8 engine, the oil pressure switch is typically screwed into the engine block. A common location for V8s of this era is near the oil filter or at the rear of the engine block, sometimes near the distributor. Look for a small, one-wire sensor.
How can I test my oil pressure switch?
A simple test can confirm if the switch is the problem. With the key in the 'On' position (engine off), disconnect the wire from the switch. The oil light should go out. Then, touch the disconnected wire directly to a clean metal part of the engine block. The oil light should illuminate. If it does, your bulb and wiring are good, and the switch is almost certainly bad.
If the light is on, does that mean my oil pump is bad?
Not necessarily. While a bad oil pump is a possibility, it's less common than a failed switch. Other causes for true low oil pressure include worn engine bearings, a clogged oil pickup screen, or simply a very low oil level. Always check the simple things first: oil level, then test the switch, then verify pressure with a mechanical gauge.
Is this a difficult repair to do myself?
No, this is a very DIY-friendly job for most owners. It requires basic hand tools, such as a wrench or a deep socket, to unscrew the old switch and install the new one. Access might be tight, but the process itself is very simple.
