We worked under the hood today and found blue, green and white paint marks on my hoses, the metal plates near the spark plugs, on my coils, the housing in the front, and "6 quarts" written on the fan shroud. Does any one know if this is a factory or dealer condition, or did the previous owner mark his hoses, etc...for a purpose that I need to investigate?
I have them as well all over the place under the hood, suspension too!
My guess is a worker goes around and looks to make sure all the parts are where they are supposed to be and marks them off with a paint pen as he/she goes along.
