    2010 Prius - 205K - finally got around to a little PM from under the car.
    1) Changed coolant in both engine & inverter circuit.
    2) Changed transaxle oil.
    3) Cleaned AC evap core.

    This was the second coolant change. The first was at 100K when I purchased the Prius in Nov 2013.
    The inverter coolant was still a bright pink & at the full level in its reservoir.
    The engine coolant had lost its bright color, but was still pink. Its reservoir had lost about 2/3 of its coolant.
    I had not touched either of the coolant systems, just monitored their level regularly (105K).

    The transaxle oil I had previously changed around 125K. On this first change it was quite black. On the change today I could still see the red color around the edges of the oil & was not nearly as black.

    86K on Michelin Defender tires (always at 44psi) - Getting a new set tomorrow from Costco.

    Still on original brakes - that is my next & hopefully last major thing to do for at least another 50K.

    Congrats on the mileage(y). I hope to be there in 2 years.

    You said the coolant was green? Do you know what was in the reservoir? Was there green coolant in the inverter loop as well?

    Engine coolant level should not have dropped like that ... hoping maybe you weren't totally thorough bleeding it last time, and it just burped later? Do you happen to remember how you went about bleeding it last time?

    At 100K the dealer changed the coolant (as part of the purchase deal).
    For the last 105K & 3+ years I had not touched or opened either coolant system, just kept a eye on the levels.
    The engine coolant level just went down very slowly over the 3+ years & 105K of driving.

    The engine coolant level appears to be staying steady since I filled it on Sat.

    Kudos for the write-up, and good to hear the Defenders are long-lived! I have a set in the garage for our son's Civic, when the snows come off.

    PM means Preventative Maintenance??
