²Engine coolant concentrations above 60% or below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
Plain water may be added in an emergency, but youmustreplace it with
a 50/50 mixture of engine coolant and distilled water as soon as possible.
Check the coolant level in the reservoir before you drive your vehicle the
next few times (with the engine cool). If necessary, add a50/50
mixtureof engine coolant and distilled water to the engine coolant
reservoir until the coolant level is at the ªcold fill levelº or within the
ªcold fill rangeº as listed on the reservoir (depending upon application).
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.
To avoid scalding hot steam or coolant from being released from
the engine cooling system, never remove the reservoir cap while
the engine is running or hot. Failure to follow this warning may result
in damage to the engine's cooling system and possible severe personal
injury.
If you must remove the coolant cap, follow these steps to avoid personal
injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
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.
Maintenance and care
226
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
toRefill capacitiesin theCapacities and specificationschapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this chapter.
Severe climates
If you drive in extremely cold climates (less than ±36É C [±34É F]):
²it may be necessary to increase the coolant concentration
above 50%.
²NEVER increase the coolant concentration above 60%.
²increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
²refer 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:
²it is still necessary to maintain the coolant concentration
above 40%.
²NEVER decrease the coolant concentration below 40%.
²decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
²decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
²refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Maintenance and care
227
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid. Refer to the scheduled maintenance
guide for the service interval schedules. If adding fluid is necessary, use
only MERCONtAT F.
