    I have a anti freeze smell. I have taken to dealer they can't find any leak. Continue to smell anti freeze. Sensor tells me it full. But my nose smells anti freeze strong oder outside truck no smell inside. Anybody having the same smell ? Is it normal as the dealer says. I never smelled this on previous trucks owned.

    If you are still having this problem you might check the turbo for residue. It can seep from the turbo but would burn off before it hit the ground.

    I've replaced a few upper radiator hoses on these. They weep where the molded plastic T is on the bottom side. Kind of hard to see it leaking, and often times won't show up when cold.
    Usually have to be towing fast and heavy for them to do it, but yeah, each one you could smell but had trouble finding due to the location and size of the leak.
