Regular Intervals (Often based on mileage or time, whichever comes first):
* Oil Change: Every 3,000-5,000 miles (or every 3-6 months), depending on the type of oil used (conventional vs. synthetic). Check your owner's manual for the specific recommendation. This also includes an oil filter change.
* Tire Rotation: Every 5,000-8,000 miles. This helps ensure even tire wear.
* Tire Pressure Check: Monthly, or before long trips.
* Fluid Top-offs: Regularly check and top off fluids as needed: windshield washer fluid, coolant (antifreeze), power steering fluid, brake fluid.
* Air Filter Replacement: Every 12,000-15,000 miles, or more frequently if driving in dusty conditions.
* Cabin Air Filter Replacement: Every 12,000-15,000 miles, or as needed if you notice a musty odor.
Longer Intervals (Mileage-based):
* Spark Plug Replacement: Every 30,000-100,000 miles (Check your owner's manual for the precise interval; it may vary).
* Transmission Fluid Change (Automatic): Every 30,000-100,000 miles (Consult your owner's manual; some recommend more frequent changes).
* Brake Pad/Rotor Inspection/Replacement: As needed, based on wear. Inspection during regular maintenance is recommended.
* Serpentine Belt Inspection/Replacement: Every 60,000-100,000 miles (or as needed based on condition).
* Coolant Flush: Every 2-3 years or 30,000-60,000 miles (consult your owner's manual).
* Battery Inspection/Replacement: Every 2-3 years or as needed.
Crucially: Always consult your 2007 Chevy Cobalt's owner's manual. It provides the most accurate and detailed schedule specific to your vehicle's make, model, and engine. The above is a general guideline and may not be completely accurate for your specific car. Ignoring scheduled maintenance can lead to costly repairs down the line.
