    Hello, now I have 115k miles on my Prius. I want to change inverter coolant.
    Do you have any special instructions for it?
    Thank you.

    Is this a Gen 3 or Gen 4?

    Profile and thread title are conflicting:cool:.

    If talking about a gen4, I have an underside shot of our Prime with regards to the inverter drain:

    What did you do to your Prime today?

    Maybe we’ll find out soon(y).

    if there is no resistance as in the photo, then the electric mode does not turn on at all. it began to happen quite often.
    If I drive without stopping for a couple of hours, then the temperature of the battery rises to 115-116 degrees. Is this normal?

    So between @Mendel Leisk ’s manual guidance and the pics I took, you should be sorted:).

    Good luck and keep us posted(y) .

    It'd be a good idea to change your profile - which shows "2012 Prius Plug-in" - or you'll get this question every time you post (or people will ignore you).

    Watch @NutzAboutBolts 3rd gen coolant change videos too, should be similar. Maintenance Mode procedure is handy too, at least for engine coolant change. I'm hitting the wall trying to find 4th gen procedure, guessing it's the same as 3rd gen (attached):
