2006 Ford F-250 Super Duty Q&A
2006 Ford F-250 Super Duty Question: Missing Coolant, heavy black smoke, no power.
I've seen the comments about the EGR and oil cooler, but am wondering why I might have the heavy black smoke vice white. This truck has been a problem child since new and continues to cause hundreds of dollar repairs on a recurring basis. Love the ride and feel. Just wish I could keep it on the road. Any help with this latest issue would be appreciated. - RickieB
if the egr cooler is leaking, it will loosen carbon in the intake and it gets to the egr valve and sticks it open. if egr valve is stuck open, it will blow black smoke. - mrfordman
