    I have a 2016 dd15 Cascadia ran fine went to start it up and noticed no coolant in tank. I refilled the coolant and started it and excessive white smoke with instant coolant loss.

    I have attached a video what do you think it is waiting for mechanic tomm to look at it

    Might be a broken liner if it's consuming coolant that fast. I wouldn't keep running it. Any coolant in the oil? What about fuel or oil in the remaining coolant?

    No coolant in oil that I can see in dip stick. Fuel filter has been getting water in filter light often and I have to drain

    That could be a blown injector cup. That usually pushes fuel into the coolant system as well as coolant into the fuel though. You see any fuel in the coolant recovery tank?

    Easy to find out. Pull the hot pipe off and look for coolant.That wouldn't account for the water in the fuel though.
