    Hi guys, so every time its cold out and i start the truck there will be a good amount of rad fluid under the truck. But I cant find out where its coming from. I noticed on the passenger side firewall there is a short piece of hose beneath the heater core tube that's open and I was wondering if you guys with the same truck have the same open hose.

    In the picture its in the lower left corner above the piece of pipe

    I also herd that there is a piece of pipe with hose clamps that could be loose and leaking on the passenger side of the motor. I believe I've found it and will try to put high pressure hose clamps on it.

    That is the ac/heater condensation drain from inside the truck. Do you smell anti-freeze in the truck with the heat on? Are the windows getting a film on them? Sounds like the heater core may be leaking if anti-freeze is dripping out of that hose. Just did one on my Dodge. What a PITA.:mechanic:

    I don't know if its dripping from there but its dripping from that side. I was just checking to see if other trucks are like that in case a damm squirrel or mouse got up in there and chewed a hose all to ****...i've done a heater core in the past and yes it is a fun filled day.
    Still not sure where its leaking from

    man are those ever hard to get at.

    On the bright side of things, I ordered a set of gauges today for the truck. Sno commander are you running any gauges?

    yea i got gauges on mine. auto meter phantoms. i like how they look and they arent as bright as others. bright enough to read them but not too bright to blind you.

    I gotta tighten mine from time to time too. It's an 06. That's the little hose you're looking for. Common problem really and a quick fix. Getting at it is the problem.
