    Hello,
    I have a 2017 Prius Two with 110k miles on it, never changed the coolant. How many gallons of Toyota 50/50 mixed coolant do I need to fill both the engine and inverter coolant?

    Thank you!

    Two US gallon bottles will do. Here's the spec'd capacities from Owner's Manual (page 732), though I suspect the drained quantity will be less:

    Thank you!
    I bought two gallon of Toyota coolant but the independent mechanix said it may take three.
    That’s why I got confused.

    No way it takes 3. I barely used 1 when I did mine, but that's probably because I didn't remove the heat exchanger hose underneath. And yes, I followed the instructions noted above. I did it at 100K and the coolant that I took out was the same color that I put in. I definitely could have gone longer.
