Massive white smoke and loss of coolant

[Dp08]

Hi, I'm new here so please bear with me. I just bought my first diesel work truck... It's an 08 powerstroke all stock with 70,000 miles on it. I've been burning through about a half a bootle of coolant (using the ford yellow) about once a month and have found no leaks! I know when coolant gets low because I blow massive white smoke (and I do mean massive amounts of white smoke) for about 10 to 30 minutes everytime I touch the gas. Any help from anybody would be greatly appreciated.

Thank you!

Does the exhaust smell like coolant? It could be a cracked egr cooler

Most likely your horizontal EGR cooler has failed. This is usually due to another coolant leak allowing air into the cooling system which overheats the cooler. The horizontal cooler takes the majority of the exhaust heat and it's much more susceptible to failure

I was thinking egr. Was just nervous it might me a future sign of a blown hg? Sure hope not as I know you have to remove the whole truck cab to get to it.

Thanks for the replies. Bringing it into dealership tomorrow so we'll see what happens.
