When adding engine coolant
Ford recommends Ford Premium
Cooling System Fluid, which is an
optimized formula that will protect
all metals and rubber elastomers
used in Ford engines for four years
or 80 000 km (50 000 miles).
It is neither necessary nor
recommended to use supplemental
coolant additives in your gasoline-
powered vehicle. These additives
may harm your engine coolant
system.
When you change or add engine
coolant, it is important to maintain
engine coolant concentration
between 40% (-24°C [-11°F]) and
60% (-52°C [-62°F]), depending on
your local climate conditions.
A coolant concentration below 40%
will result in a loss of freeze
protection. A concentration above
60% may cause the engine to
overheat on a warm day.
Refer to Lubricant specifications
in the Capacities and
specifications chapter. Use only a
premium nationally-recognized
brand name engine coolant or
equivalent.
