2. Essential Maintenance for Your 96 Cutlass Supreme

Regular maintenance is key to preventing major issues and extending the life of your Cutlass Supreme. Following a schedule helps keep your car running smoothly. Here are some essential maintenance tasks:

Oil Changes and Fluid Checks

Regular oil changes are crucial for engine health. Check all fluids regularly.

• Oil Changes: Change the oil and filter every 3,000 to 5,000 miles, or as recommended in your owner's manual. Use the correct type of oil as specified by the manufacturer.
• Coolant Check: Ensure the coolant level is adequate to prevent overheating. Flush and replace coolant every 2-3 years.
• Transmission Fluid: Check transmission fluid levels and condition regularly. Change the fluid as recommended (typically every 30,000-60,000 miles).
• Power Steering Fluid: Check fluid levels, and flush and change if necessary.

Tire Maintenance

Proper tire maintenance ensures safe driving and extends the life of your tires. This includes:

• Tire Pressure: Check tire pressure regularly and inflate to the recommended PSI (found on the driver's side door jamb).
• Tire Rotation: Rotate your tires every 5,000-7,000 miles to promote even wear.
• Tire Inspection: Inspect tires for wear, damage, and proper tread depth.

Brake System Inspection

Ensure your brakes are in good working order for your safety:

• Brake Pad and Rotor Inspection: Check the thickness of brake pads and the condition of rotors during routine maintenance.
• Brake Fluid: Flush and replace brake fluid every 2-3 years, as it absorbs moisture over time, which can decrease braking performance.
