Hello,
The shop manual for my '99 Windstar calls for "Premium Engine Coolant, E2FZ-19549-AA" meeting "Ford specification ESE-M97B44-A"
It later offers the following cautions:
"Caution: Do not use Extended Life Engine Coolant F6AZ-19544-A meeting Ford specification WSS-M97B44-D(orange color)."
and
"Caution: Do not mix Standard (green) Coolant with Extended Life Coolant (orange)."
Based on the hints provided (color, words like "standard") and the recent DexCool discussion on this list, I'm under the impression that I should use an ethylene glycol based coolant and not the DexCool.
Is this correct, and are there any special constraints imposed by the Ford Spec ESE-M97B44-A?
Thanks,
Powell
