FORD 2001 F-150 v.1 - Manual (Page 158)

Recycled engine coolant
Ford Motor Company recommends the use of a recycled engine coolant
produced by Ford-approved processes.
Not all coolant recycling processes produce coolant which meets Ford
specification ESE-M97B44-A. Use of a recycled engine coolant which
does not meet the Ford specification 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.
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%.
• decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
