    Hi everyone, I’ve recently joined this community and I’m excited to share and learn. I own a 2007 Prius (Gen 2), and I’d love to hear your tips and experience on long-term maintenance.
    A few specific questions I have:

    What maintenance tasks do you recommend doing before serious trouble starts (e.g. inverter, hybrid battery, coolant, etc.)?

    Which upgrades or replacements have given the best value/performance improvement for the Gen 2?

    Any advice on reliable sources for OEM parts or trustworthy remanufactured components?

    Thanks in advance for all the help. Looking forward to contributing to this community!

    How many miles does your 2007 have? That will affect some advice.

    Otherwise change transmission fluid, both coolants, brake fluid

    Change oil and filter every 5k mileage

    Clean the hybrid battery fan

    Attached a couple of spreadsheets (and pdf conversions), table format summary of the event-by-event schedule published by Toyota USA. One per the booklet, the other extrapolated to 240k miles.

    I'd be looking into:

    1. Brake inspection
    2. Brake fluid replacement
    3. Coolant replacement (engine and inverter
    4. Coolant pump replacements (engine and inverter), plus coolant thermostat on the engine.
    5. PCV valve replacement
    6. Spark plug replacement
    7. Engine oil and filter replacement
    8. Engine and cabin air filter inspect and/or replacement
    9. Wiper blade inspect and/or replacement
    10. Throttle body cleaning
    11. Tire inspection
    12. Rodent proofing
    13. 12 volt battery inspection and maintaining
    14. Hybrid battery inspection and maintaining
    15. Thorough wash including wheel wells, occasional waxing, interior cleaning

    Depending on where you are in the "USA", rust mitigation may be a consideration as well.
