What colour is the coolant currently in the engine?
A Mk3 Mondeo that runs the 1.8 and 2.0 litre Duratec engine should use O.A.T antifreeze (organic acid technology) which is usually a fluorescent pinky/orange colour.
I'd assume Morgan would use the correct Ford Super Plus Premium WSS-M97B44-D which is orange in colour, if they did then something from any manufacturer that confirms to WSS-M97B44-D spec will be fine, it doesnt need to be the Ford/Motorcraft brand.
Confusingly some companies like Comma dye their WSS-M97B44-D red rather than orange, so don't go by colour, always make sure it shows WSS-M97B44-D in the spec on the back of the container.
