Oldsmobile Cutlass Supreme Coupe 1970

COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The 1970 Oldsmobile Cutlass Supreme Coupe, like many classic cars, has its share of common issues. Here are some of the typical faults reported by owners:

1. **Electrical Issues**: Problems with the wiring, such as blown fuses and faulty switches, are common. For example, the neutral safety switch located on the steering column can sometimes fail.

2. **Cooling System**: Overheating can be an issue, often due to a faulty thermostat or cooling fan.

3. **Transmission Problems**: Issues with the torque converter or slipping clutches in the transmission can occur.

4. **Air Conditioning**: The air conditioner fan relay may need replacing, and the blower motor might only run on high.

5. **Lighting**: Problems with the headlights, such as the bright lights working but not the low beams.

6. **Engine Performance**: Changes in RPM without changes in engine setup or environment can indicate issues with the torque converter or transmission.

Despite these common faults, the 1970 Oldsmobile Cutlass Supreme Coupe remains a beloved classic among car enthusiasts. Regular maintenance and attention to these areas can help keep it running smoothly.
