A few weeks ago, the Max overheated on my wife. I tested the thermostat, and it wouldn't open, so I replaced it and also the lower hose for good measure. All was good until today, when she saw fluid leaking. Turns out it was coolant. I found the leak--a pinhole leak in the hose that runs from a connector on the bottom of the throttle body to a connection towards the front. I could see it jetting out. It made a nice green lake in Knock Sensor Valley.
The hose is only about 5" long, and I circled part of it in red here: http://tinyurl.com/kpxz6el
So I replaced that hose and took it for a test drive, but it's still leaking. I can't really tell where the leak is coming from. It's dripping on the tranny housing, about where the red circle is in this picture: http://tinyurl.com/ltyvxly
It seems to coming down just about where the red X is in the first picture.
I'm going to have to pull the air box and air intake to see under there, but I won't be able to run the engine while I'm looking. It looks like there is a formed cast iron (or aluminum, or whatever) piece that runs back from where the upper radiator hose connects, but there are too many hoses in the way to really see. Is there a usual suspect for leaking in that area?
