We have a 2016 Cascadia, DD15, 474000 miles. Smell of
We have a 2016 Cascadia, DD15, 474000 miles. Smell of burning antifreeze, not sweet smell in the cab while the heat is on or vents open. Rear cabin heater core burst while on a mountain under heavy load, and was bypassed. Front heater core begin leaking next, and was replaced. Radiator cap began to seep. Obviously, we have excess pressure in the system. One box required replacement, and EGR cooler was "burned through", and hence, replaced at dealer as well. In less than 8k miles, the problem is apparent again. Smell is heavy in the cabin with the vent open. Mild smell while in A/C mode. Engine power seems to fluctuate, and rumbles loudly under load now. Was quite before this trouble. Also, economy drops dramatically. … read more
