    Just finishing an engine swap for my new to me 2007 Prius. Bought it thinking it was a head gasket failure, but it was much worse than that (broken rods and bent internals etc). Never done anything this comprehensive before.

    Finishing up the engine swap, and I'm having a hard time locating where the coolant hoses from the throttle body go. @Mendel Leisk posted in a different post this attached image diagram that show the hoses in question (16261 and 16264 in the top right corner)


    Here are pictures of the throttle body coolant hose origin points and where I think the endpoint of 16261 (left) is. I have no idea where 16264 (right) goes. I tried to follow the diagram but don't see anything it could attach to.

    I've also attached pics of the coolant hoses themselves and I'm hoping someone can confirm these are the right hoses. These are the only two hoses I found on the ground, but they seem to fit the bill.
