Engine coolant refill procedure-3.8L V6 engine
Use the following procedure when refilling
the cooling system of a vehicle equipped
with a 3.8L V6 engine. Failure to follow this
warning may result in damage to the engine and
engine cooling system.
The following procedure should be used when
refilling the cooling system of a 3.8L V6 engine after
it has been drained or become extremely low.
1. Remove the cap
from the engine
coolant reservoir.
2. Open the cooling
system vent plug.
3. Remove the radiator
cap as previously
outlined.
4. Add a50/50 mixtureof engine coolant and
distilled water to the radiator until full.
5. Add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir until
the coolant level is at the ªcold fill levelº as listed on
the reservoir.
6. Close the cooling system vent plug.
7. Reinstall the engine coolant reservoir cap.
8. Reinstall the radiator cap.
9. Start and idle the engine until the upper radiator
hose is warm (this indicates the thermostat is open
and coolant is flowing through the entire system).
10. Immediately shut the engine off.
11. Wrap a thick cloth around the radiator cap and
cautiously remove the radiator cap.

12. Add a50/50 mixtureof engine coolant and
distilled water to the radiator until full.
13. Reinstall the radiator cap.
14. Check the coolant level in the reservoir before
you drive your vehicle the next few times (with the
engine cool).
15. 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 as listed on the reservoir.
If you are unsure of how to operate the cooling
system vent plug when adding engine coolant to the
3.8L V6 engine, contact your dealer.
Engine coolant refill procedure-4.6L V8 engine
The following procedure should be used when
refilling the cooling system of a 4.6L V8 engine after
it has been drained or become extremely low.
1. Remove the pressure relief cap from the engine
coolant reservoir as previously outlined.
2. Slowly add a50/50 mixtureof engine coolant
and distilled water to the engine coolant reservoir
until the coolant level is at the ªcold fill levelº as
listed on the reservoir.
3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper radiator
hose is warm (this indicates the thermostat is open
and coolant is flowing through the entire system).
5. Shut the engine off and let it cool.
6. Remove the pressure relief cap from the engine
coolant reservoir as previously outlined.
7. Add a50/50 mixtureof engine coolant and
distilled water to the engine coolant reservoir until
the coolant level is at the ªcold fill levelº as listed on
the reservoir.
8. Reinstall the pressure relief 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.
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 the
Capacities and specificationschapter.
Fill your engine coolant reservoir as outlined in
Adding engine coolantin 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.
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.
