• Coolant replacement: Often around every 5 years or 60,000 miles, whichever occurs first (verify per manual). If the coolant looks dirty or corroded, flush and replace sooner.
• Transmission fluid service: For automatics, many manufacturers recommend ATF drain/refill every 30,000–60,000 miles depending on usage and manual. For manuals, follow the manual’s guidance; not all manuals require a regular drain.
• Cabin air filter replacement: If equipped, typically every 15,000–30,000 miles or once a year, whichever comes first.

ENGINE DESIGN NOTES (RELEVANT FOR THIS MODEL)

• Timing belt vs timing chain: The Mazda6 engines from this era generally use timing chains, not timing belts. This means there isn’t a scheduled timing belt replacement interval. If you have any unusual engine noise or timing concerns, address them with a trusted technician and consult the service manual for specific chain maintenance guidance.
• Spark plugs: Replacement interval depends on plug type used (conventional, platinum, iridium). Many modern Mazda6 engines are designed for longer intervals (60k–100k miles); always verify based on your exact spark plug specification.
• Transmission: Automatic transmissions in these vehicles typically require attention to ATF as per manual schedule. If you have a manual transmission, clutch wear and hydraulic linkage should be inspected if you notice slipping, noise, or difficulty shifting.
