Can someone post or send me a picture of the front driver side back in the engine bay directly above the frame there is a hose coming out of the firewall. I've searched the FSM and can't find what it's supposed to connect to (which I have assumed that it connects as I've never noticed it leaking before.) It's leaking a cold, clear, non-odorous liquid. My girlfriend was driving the truck last night downhill on a newly paved road when a horrible clunking/banging sound came from that area, immediately pulled over and I tried to take a look at it but it was dark and I had a terrible migraine so was rather useless. Still can't figure out what the hell it is and I'd like to have some general idea before I take it to the dealer or a mechanic friend of mine.
