2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Technical Service Bulletin # 04-06-04-051C Date: 120419



Fuel System - Fuel Injector Maintenance Cleaning



INFORMATION



Bulletin No.: 04-06-04-051C



Date: April 19, 2012



Subject: Maintenance Cleaning of Fuel Injectors



Models:



2013 and Prior GM Passenger Cars and Trucks



Supercede:



This bulletin is being revised to add model years and Parts Information. Please discard Corporate Bulletin Number 04-06-04-051B (Section 06 -



Engine/Propulsion System).



General Motors is aware that some companies are marketing tools, equipment



and programs to support fuel injector cleaning as a preventative



maintenance procedure. General Motors does not endorse, support or acknowledge the need for fuel injector cleaning as a preventative



maintenance procedure. Fuel injector cleaning is approved only when performed as directed by a published GM driveability or DTC diagnostic



service procedure.



Due to variation in fuel quality in different areas of the country, the only preventative maintenance currently endorsed by GM regarding its gasoline



engine fuel systems is the addition of GM Fuel System Treatment PLUS added to a tank of fuel at each oil change.
