FORD 2003 Mustang v.2 - Manual (Page 174)

Ford Motor Company does NOT recommend the use
of recycled engine coolant in vehicles originally
equipped with Motorcraft Premium Gold Engine
Coolant since a Ford-approved recycling process is
not yet available.
Used engine coolant should be disposed of in
an appropriate 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 this
chapter.
Fill your engine coolant reservoir as outlined in
Adding engine coolant in this chapter.
Severe climates
If you drive in extremely cold climates (less than
–36° C [–34° F]):
• It may be necessary to increase the coolant
concentration above 50%.
• NEVER increase the coolant concentration
above 60%.
• Increased engine coolant concentrations
above 60% will decrease the overheat
protection characteristics of the engine
coolant and may cause engine damage.
• Refer to the chart on the coolant container
to ensure the coolant concentration in your
vehicle will provide adequate freeze
protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
• It is still necessary to maintain the coolant
concentration above 40%.
• NEVER decrease the coolant concentration
below 40%.
