Have a 2004 F-550. Hose was dragging underneath. Turned out to be a hydraulic fitting that attached to the bottom of a pulley driven unit. Followed hose up around driver side of engine
compartment, and then under the rad/a/c condensor/transmission
cooler and it attached at the top of the transmission cooler passenger side. Ford parts dealer cannot find the hose I'm talking about in his computer. Fitting into the cooler is just a standard 90 degree with a nut; there's another 90 degree ftting just below it. Parts guy maintains there shouldn't be a hydraulic pump driving the transmission cooler, but that's the way it looks. I don't think there's a problem running the bus as is for now unless you were heading to the mountains. Please advise what this hose is doing. Thanks.
JA: Have you checked the fluids recently?
Customer: I checked the transmission fluid with the truck running. Seems like the fluid level is only on the bottom set of hash marks, not the top, so it appears to be down.
JA: Are you fixing your F550 yourself? What have you tried so far?
Customer: We'd like to fix it with the students in the Metals shop. This is an F-550 with the 6.0 L turbodiesel, on a coach bus frame. The boss uses if for sports teams. It has a lot of different drivers, and it only gets into the bus barns twice a year for maintenance.
JA: Anything else you want the mechanic to know before I connect you?
