s Guide says "Use only Ford G05 Engine Coolant or a
premium coolant that meets Ford spec.WSS-M97B51-A1 . But later
on the "Capacities and specifications page it shows
ESE-M97B44-A as the required coolant. I wonder what the
difference is and which one the dealer would want to sell me?
Here is a coolant I was considering to use (opinions naturally
welcome) : http://www.peakantifreeze.com/peak_g...time_5050.html
BTW, a friend told me that adding potassium or sodium nitrite
to the coolant will increase or restore the coolant's ability to
prevent rust/corrosion. It is sold in auto supply stores. I
suppose Ford would reject this action.
