Yes , it came from the factory with a 50 / 50 mix of antifreeze and distilled
water in the cooling system . The antifreeze in the mixture provides freeze ,
boiling , and corrosion protection ( the corrosion protection does " wear out " )
The other parts in the engine cooling system , such as the water pump ,
engine thermostat , engine cooling fan , hoses etcetera also need to be
working properly
The engine cooling system capacity , including the reservoir is 12.8 quarts on a 1997 Mercury Mountaineer So , a 50 / 50 mix of antifreeze and preferably distilled water ( that's the way it came from the factory ) would take * ( 6.4 quarts of antifreeze ) *

Passenger ===================================================== Actually , bank 2 is the drivers side of the engine in a Mercury Mountaineer
what does a insufficient coolant temperature for closed loop fuel control mean and what can i do to fixs it on a mercury mountaineer 1997 engine is a 5.0
