Coolant issue

Hey guys got a little issue with my truck, truck is 2010 6.4 27k all stock. I notice my coolant is black, first thought was my oil cooler was leaking so I brought it to the dealer they said the coolant is burnt they reccomended a flush. They asked if I had a tuner I said no, so they said it could be just from regenning. Is this true? Shouldn't they cover the flush since it should be able to handle the heat of the motor? Any input is great guys thanks!!

I am pretty sure coolant doesn't turn black from re-gening. Take a sample and see if it is engine oil. I would probably say it is more likely to be an oil cooler issue. Not 100% sure of this but maybe a ruptured egr cooler could contribute to this issue also

iv never seem coolant be "burnt" , thats why im thinking its either oil or something along those lines. Never seen it in any cars iv worked on, i dont work on diesels so not sure if coolant could get burnt from the egr coolers when the exhaust gets hot from regen. The way i see it is that the dealership is just blowing smoke up my a$$ and not wanting to do warrenty work

I'd send a sample off to someone. Not sure if Blackstone will test coolant, but you could try.

I would also send off a sample and see what it is. It wont do any good to flush it if there is a problem that needs to be corrected first.

I would call blackstone and ask. I am pretty sure they can sample it.
