Hey y'all. I have 2010 F150 XLT with a 4.6L 3V engine that is due for a cooling flush. When searching for coolant the recommendations are different than my manual. My manual calls for orange but motorcrafts chart says yellow. Maybe my 2010 has a 2011 engine? Anybody (maybe a ford dealer mechanic?) know what I should use?

 

Yellow has replaced orange but is backwards compatable so if you still have some orangein the system you'll be ok to mix.
