Regen, coolant temps, smoke

[Why_rick]

So, I’m new with this ED and when I was leaving work today, there was a regen to do. No biggie, I’ll just hop on the freeway and drive around a bit. Engine seems to be running hot (around 240°) and during the regen, I started to have white smoke billowing out the exhaust. Is this normal? Also, after a few miles I had to head up a hill. Temp went higher and I lost power. I was able to ease it off the freeway and stopped at a lot and let it idle and cool down a bit. I think the regen is complete bit my coolant temp is still staying around 240°

White smoke leads me to believe coolant is being burned off. Power was lost due to high temps and engine being de-rated as a precaution.

Coolant could be lost through the turbo or EGR cooler along with other possibilities. Is your coolant level low?

I didn’t think to check that before, but yes, it looks like the coolant is low.

Coolant must have being burned off. I added 2 gallons of fluid this morning and brought it to the dealership. Engine light came on also. Not what I wanted to deal with in my first week of ownership. Hopefully this is just an isolated issue and not a lemon.

The turbo and EGR are both liquid cooled by the coolant and I'm going to guess it's either a leak at the turbo or at the EGR cooler. In any case I hope the repair goes well and it's the last problem you experience.

Thanks John. When I made it to the dealership, temps were good (right around 200°), coolant was still topped off, and no leaking. I’ll update once I get the eval from the mechanic.

At this point they’re saying it’s an issue with a temperature sensor and it’s going to be reprogrammed. The shop pressure tested and it’s not leaking coolant and everything else is fine. Should have it back tomorrow! Thanks guys for your input.

Truck is running great after this repair!

Keep an eye on your coolant level, it needs to stay at or above the seem on the reservoir.
