If it is yellow then Ford Gold. It's just a G-05 clone. (color does not matter) It is good for 5yrs or 100k. Whatever cheapest G-05 you find will work perfectly.

I saw mercury gm and thought you where talking about a GM based mercury engine for boats. So I was a little confused at first why you wore looking for coolant.

Ford Gold and Zerex G-05 have the same chemistry, so use whatever is cheaper and drain and fill every 5 years.

would this apply to a 2001 crown vic? I looked in the overflow and it looks somewhat greenish. AFAIK its the factory fill.

I think Ford used original green till '03 in cars when they switched to G-05. Ford backspeced G-05 to'99.

FWIW, both our Expeditions had Ford yellow in them (G-05) when new. That would be our 2002, and mom and dad's 2000.

I don't remember what our '98 had unfortunately.
