The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

Some Ford F-250 Super Duty owners report experiencing intermittent brake dragging issues, often linked to frequent caliper failures and overheating. These problems can occur when calipers lock up, causing brakes to drag and potentially leading to steering difficulties. Additionally, excessive brake dust from specific wheels may indicate caliper issues. Insufficient lubrication on caliper slide pins can also contribute to sticking, particularly under heat. Owners should be aware of recalls and Technical Service Bulletins (TSBs) related to brake components, as these may highlight known problems. Regular maintenance, including checking and cleaning slide pins and ensuring proper lubrication, is crucial to prevent these issues. If problems persist despite maintenance, seeking assistance from a qualified diesel repair specialist is recommended for effective diagnosis and resolution.
