    I drive a 2012 cascadia with an isx cummins. I had a small hose on top of radiator to surge tank replaced. They did top it off. Idled truck that night and next morning I was seeing blue or white smoke from exhaust. Had to put 4 gallons in. Drove 45 miles and idle bumped for an hour and no smoke and level was normal. Drove another 90 miles to get home. Checked level next day after it had cooled off and looks like I'll need another 2 gallons. I'm not seeing anything on the ground, so coolant is going somewhere. Thoughts?

    Well, coolant loss problems don't magically go away, not sure what the smoke was all about, but if it's going through the motor, it will smoke all the time. I think trucks hold like 11 gallons of coolant, so the shop didn't top it off and could have been that low. Coolant is a funny thing, and pressure pockets take a while to burp themselves out. I'd just keep an eye on it.

    Do 2010 EPA motors still have EGR? If so, then my bet would be EGR cooler.
