    So I took my 20016 in for 50,000 mile service and they said I need to change the engine and electric motor coolant ( I gather they're same type but separate circuits) for $260. According to the manual the first change of these should be 100k and ~120K miles each. Also $260 seems steep. I told them I'd put it off until my next service
    1. does their recommendation to change and the interval sound fishy?
    2. Also how difficult a job is this?
    3. is there a way for me to diagnose the coolant condition myself? e.g. by color, smell, etc?

    welcome!
    1) yes, or more like lying to make money

    2) its probably worth $260. for both at a dealer, i've seen much worse

    3) nah, just follow toyota's schedule that came with your car.

    According to Toyota USA first engine coolant change is 100k or 10 years (whichever comes first), and first inverter coolant change is 150k or 15 years.

    Thereafter both are 50k or 5 years.

    Dealer just did mine for the first time at 100,000 miles on my 2017 Prius 4. I trust them on pricing, and their charge was $257.

    Just as a matter of interest, was it discoloured at 100K miles ?
