6.7L Diesel – Diesel Exhaust Fluid (DEF) Service Tips
All 6.7L diesel equipped F-super duty vehicles are equipped with a Diesel Exhaust Fluid (DEF) system in order to aid in Nox reduction.
In many cases, DEF system concerns are related to petroleum contamination or misdiagnosis.
This General Service Bulletin is intended to aid in the diagnosis of the DEF system and help aid in determining if the system has been contaminated.
Petroleum contamination of the DEF system is non-warrantable.
See GSB: G0000012 for details.
