    2010 Toyota Prius... in multi-day process of doing a head gasket replacement.

    I am on Toyota Techinfo site and can't even find out what it is called or where it is in any diagrams.

    It's the largest hose that connects to the drivers side of the cylinder head.

    Update... this one (and of course I mean while it's IN the vehicle) removing it here would be easy:

    If you can’t take it off I suggest you go no further

    Not a helpful reply. I'll clarify a bit....

    The hose is already off (the cylinder head is off for that matter). The way we removed it was not ideal.

    I just want to see what the official Toyota way of removing the cylinder head / replacing cylinder head is when dealing with this hose. I have Techinfo access right now and browsing around can not seem to find this hose, or this step anywhere in the process.

    If you or anyone else happens to know what the hose is officially called that would be helpful.

    No. I'm talking about the rubber hose that connects to the drivers side of the cylinder head.

    Added the picture to first post. Although that image gives me indication that removing it lower..unbolting the hard pipe and removing the other hoses may be easier than trying to remove it at the cylinder head side with that double-clamped monstrosity holding it in place.

    The short rubber hose is connected to a metal pipe. The metal pipe has a bracket that bolts to the transmission. The bolt faces the front of the car and is a 12mm. Once the bracket is out of the way, you can remove the entire hose assembly with the pipe and the bracket.

    Thanks! I guess that's how we'll put it back in then. Or I suppose if the bracket is unbolted, then we can at least get some wiggle room to put the hose back on the head.

    Connect the short hose to the head, then bolt down the bracket.

    Also, you probably know this, but the rad hose needs to be removed before you can access the hidden bolt.
