What were the operating conditions when all this happened? Weather, temp on truck, what were you hauling, any performance adders, etc.

Normal engine operating temps,75F oat,no load,level road, noticed vapor from exhaust that quickly got worse.have been hauling 10,000# trailer for 5 weeks,4000 miles,no grades,90F max temp.Approx 1 quart coolant loss .No coolant in oil,vapor smelled of antifreez.Towed to dealer(only choice)no one else for 200 miles or more would touch it.Not the best day ever!

Never heard of that happening before on a duramax with that low of mileage. That's just a case of bad luck. Hope everything works out the best for you. Keep us posted.
