I was looking around under the hood and noticed a plastic T with two rubber hoses attached, and one end of the T open with no hose. This is on the drivers side in the engine compartment toward the fire wall. Why would this not have a hose on it or at least some type of filter?
There's another thread on it, or, I think it's the same hoses: http://priuschat.com/forums/gen-iii...hooting/92898-missing-coolant-hose-clamp.html
I looked at this thread first. I don't think it's the same. On mine no hose exist, and it is further back toward the fire wall.
Most people own cell phones. If you do not, I am sure you know someone that does. 99.99999% of cell phones have a camera Take a pic and post it for all to understand your issue.
If it's what I think it is, it's the coolant bleeding port, should have a white screw in stopper. Again, this a is all "think", release the stopper to purge the cooling system of air when refilling. Anyhow, that's what it looks like to me.
I will try and get a picture later today or tomorrow. It is an open connection with nothing attached, and no plug.
