    2012 Prius plugin. 286k miles original
    Owner. Replaced water pump and thermostat. Car ran great for a few months. Overheating light came on. Water is boiling over and out of reservoir. Fans aren’t coming on. Where is the relay located and fuse location? I’m thinking that’s the culprit. Are there fuses for the radiator fans? Also would the head temp sensor be the culprit?

    I replaced the head gasket via YouTube guidance. The car runs like a champ again.

    Beware.

    Head gasket failure can sometimes be a symptom of another problem.
    I'm thinking that in some cases, heart failure occurs NOT because of a defective heart....but from eating too many cheeseburgers.

    in gen 3, it is always because of the rings and pistons, leading to clogged egr

    It would probably be hard to construct a shorter sentence that would demand "and this has been established how, exactly?" for so many of its constituent claims.
