Maintenance and care
209

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 WSS-M97B51±A1. Use of a recycled engine coolant which
does not meet the Ford G05 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.

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

the level until it reaches the correct operating range. Be sure to put the
cap back on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to your scheduled maintenance guide for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated area for normal operating temperature or ambient
temperature.
