    2012 Prius V Radiator Coolant is very low. It shows on the bottom of the container. I noticed when I saw the low coolant light on the dashboard.

    I filled the container and it went down again the next day. No low coolant light is on yet.

    It’s not the gasket, I didn’t see in the engine when I opened the oil cap.

    I’ll be changing oil soon.

    Head Gasket-using coolant internally. Does it run rough at start up? No leaks-coolant has to be going somewhere-Most likely internal consumption.

    Sounds like ongoing gen 3 head gasket failure.

    not seeing in the engine when opening the oil cap is all about perspective.

    Pulling the spark plugs and inserting a boroscope, preferably one that can look "over it's shoulder", will allow you to check for evidence of coolant leaking past the head gasket, the usual head gasket failure condition with these gen 3's.
