Mercury Sable 1999 - Manual (Page 145)

Do not use alcohol or methanol antifreeze or any
engine coolants mixed with alcohol or methanol
antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm
your engine cooling system. The use of an improper
coolant may void the warranty of your vehicle’s
engine cooling system.
Recycled engine coolant
Ford Motor Company recommends that Ford and
Lincoln-Mercury dealers use recycled engine coolant
produced by Ford-approved processes.
Not all coolant recycling processes produce coolant
which meets Ford specification ESE-M97B44–A, and
use of such coolant may harm engine and cooling
system components.
Always dispose of used automotive fluids in a
responsible manner. Follow your community’s
regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling
system can hold, refer to Refill capacities in the
Capacities and specifications chapter.
Have your dealer check the engine cooling system
for leaks if you have to add more than 1.0 liter (1.0
quart) of engine coolant per month.
Severe winter climate
If you drive in extremely cold climates (less than
–36°C [–34°F]), it may be necessary to increase the
coolant concentration above 50%. Refer to the chart
on the coolant container to ensure the coolant
concentration in your vehicle is such that the
coolant will not freeze at the temperature level in
which you drive during winter months. Never
increase the engine coolant concentration above
60%. Leave a 50/50 mixture of engine coolant and
water in your vehicle year-round in non-extreme
climates.
