hello new to the board I have a 2002 v8 5.4 f150 yesterday I had a coolant flush done at dealer truck came with gold yellow coolant well they screwed up and put the green stuff in went back today they did another flush they claim to have used the yellow this time but is still GREEN (i checked it from the bottom radiater screw) they tell me it is impossible to get it all out am i getting screwed??? is it ok to leave it the way it is any suggestions thanks

 

Sucks that you had to waist all that time because of their screw up....Anyways I think you should be fine. I can't remember all the technical names of the coolants but the old green and the yellow I believe are interchangeable with each other. The yellow is just less toxic and more environmentally friendly. Now, if you truck was newer (say 2008 or newer) I would be worried. Ford fills those with a coolant that is more gold in color. This coolant is NOT compatible with any of the two other coolants. I think there might be a better explanation of this in your owner’s manual.

Good luck!
