Oil Change:
Every 3,000-5,000 miles or 3-6 months, depending on driving conditions and oil type used. Check manual for specific recommendations based on oil viscosity.
Engine Coolant:
Flush and replace every 30,000-60,000 miles or 2-4 years. Use Dex-Cool (GM's orange coolant) for later models, though specific type may vary.
Transmission Fluid:
Automatic: Check every oil change, replace fluid and filter every 30,000-50,000 miles. Manual: Inspect fluid level as needed; replacement intervals vary greatly.
Spark Plugs:
Replace every 60,000-100,000 miles, depending on plug type (e.g., platinum or iridium).
Timing Belt Or Chain:
2.2L OHV engines use a timing chain (generally maintenance-free). 2.4L DOHC and 2.3L DOHC engines use a timing belt, typically requiring replacement every 60,000-90,000 miles.
