- The same manual says yellow can service vehicles with orange or yellow coolant, but a vehicle manufactured with yellow must stay on yellow. [2]

Orange, yellow or gold?
Ford has used several coolants over the years. Orange (WSS-M97B44-D) and yellow (WSS-M97B57) are the current pair in the manual we cite; gold (WSS-M97B51-A1) is an earlier Ford spec named in Ford's position statement. Colour is not a spec, so read the code on the reservoir or in the manual. More in best coolant for Ford.
