    I can’t figure out how to drain the engine coolant from my 2016 Prius two. I opened the yellow drain plug on the bottom of the radiator and it only drained the fluid in the inverter reservoir. I also disconnected a hose on the very bottom of the radiator on the passengers side and that also drained the inverter reservoir after I had filled it back up. Please help. Thank you

    Yeah the front radiator houses both the engine and inverter radiator, so you've got to be careful. I'd suggest to get a short term Tech Info subscription and download the info before proceeding. As far as I know there's no "repair manual" pdf for 4th gen.
