Review OLDSMOBILE Supreme Instrument Cluster Gauges Speedometer fits CUTLASS 1978–1980

The Oldsmobile 25016635 cluster gauges are original equipment parts designed specifically for use in 1978-1980 Oldsmobile Cutlass Supremes. These gauges are essential components of the vehicle's dashboard, providing crucial information to the driver regarding engine RPM, fuel level, coolant temperature, and vehicle speed.

The speedometer is the largest and most prominent gauge in the cluster. It is graduated to read up to 140 miles per hour, with a red warning zone ranging from 80 to 110 miles per hour. The speedometer needle sweeps smoothly across the dial, providing an accurate and easy-to-read indication of vehicle speed.

The fuel gauge is situated to the left of the speedometer and displays the level of fuel in the tank. The gauge is graduated to represent the fuel level from empty to full, with a red warning zone indicating when the fuel level is low. The fuel gauge is designed to provide an accurate and reliable reading of the fuel level, ensuring that the driver is always aware of the vehicle's fuel status.

The temperature gauge is located to the right of the speedometer and is used to monitor the engine coolant temperature. The gauge is graduated from low to high, with a red warning zone indicating when the engine temperature is too high. The temperature gauge provides an essential function by alerting the driver to potential engine overheating, ensuring that the vehicle can be safely operated.

The RPM gauge is situated in the center of the cluster, between the speedometer and the temperature gauge. It is graduated from idle to 6,500 RPM, with a red warning zone indicating when the engine RPM is too high. The RPM gauge provides the driver with essential information about engine performance and load, allowing for optimal driving conditions and engine longevity.

These Oldsmobile 25016635 cluster gauges are manufactured to meet or exceed original equipment specifications, ensuring that they provide accurate and reliable readings. They are designed to fit seamlessly into the 1978-1980 Oldsmobile Cutlass Supreme dash, providing a factory-installed look and feel. These gauges are an essential investment for any Oldsmobile Cutlass Supreme owner looking to restore or maintain their vehicle's original appearance and functionality.

Oldsmobile 1978-1980 Cutlass Supreme Cluster Gauges (specifically the speedometer with part number 25016635) can be an intriguing purchase for classic car enthusiasts or those restoring older vehicles. Here are some potential pros and cons to consider before making a decision.

1. Authenticity: Original, vintage parts add to the value and authenticity of a classic car. Installing new aftermarket speedometer might not maintain the same aesthetic appeal as the original one.

2. Functionality: Older cars often have unique electrical systems, and new aftermarket gauges might not be a direct fit. Original OEM parts are more likely to work seamlessly with the existing wiring and connectors.

3. Collectability: For collectors, having original parts can increase the value of their vehicle.

1. Availability: Older parts can be harder to find, and when available, they might be more expensive than new aftermarket parts.

2. Condition: Used parts might not be in perfect condition. They could have cracks, scratches, or worn-out markings that need restoration.

3. Compatibility: Depending on the specific car and its condition, the old part might not fit perfectly or might require additional modifications to install.

4. Cost: Older parts can be more expensive than new aftermarket alternatives.

5. Risk of malfunction: Older parts might be more prone to failure due to their age and wear.

Deciding to buy an Oldsmobile 1978-1980 Cutlass Supreme Cluster Gauge (specifically the speedometer) involves weighing the benefits of authenticity, functionality, and collectability against the potential drawbacks of availability, condition, compatibility, cost, and risk of malfunction. If the priority is a perfect fit, seamless installation, and minimal restoration effort, a new aftermarket gauge might be a better choice. However, for those who value authenticity and the look of original parts, the Oldsmobile OEM part could be worth the investment, despite the potential challenges. Ultimately, the decision depends on the individual's preferences, priorities, and resources.

Details:

Again untested unknown if gauges work. Speedometer moves freely. Odometer reads 43k. Please examine photos before buying.

This would be great for a hot rod or rat project as it isn't the nicest cluster out there. The crystal isn't bad. The needles, gauge faces and bezel has surface rust. The letters/numbers are still readable.

The circuit board doesn't look bad. No cracks or breaks.
