Problem overview

Some Ford F-350 Super Duty 6.0 owners report experiencing white exhaust smoke, which may be attributed to several issues, including EGR problems. This white smoke can result from condensation, coolant leaks, cracked cylinder heads, or blown head gaskets. Additionally, some owners find that a leaking EGR cooler can cause antifreeze to enter the exhaust system, producing steam and contributing to the white smoke. It is crucial for owners to diagnose the specific cause of the white smoke to effectively address the issue and prevent further complications. Therefore, it is recommended that affected owners have their vehicles inspected by a qualified mechanic to identify the exact problem and perform necessary repairs.
