Engine coolant refill procedure- OHV V6 engine
Note:Use the following procedure when refilling the
cooling system of a vehicle equipped with a 3.8L V6
engine. Failure to follow this procedure 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“cold fill level”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 the engine and run it at 2000–2500 rpm
until the upper radiator hose is warm (this indicates
the thermostat is open and coolant is flowing
through the entire system).
10. Shut the engine off and allow it to cool.
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“cold fill
level”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“cold fill level”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“cold fill level”as listed on
the reservoir.
8. Reinstall the pressure relief cap.
9. Check the coolant level in the reservoir before
you drive your vehicle the next few times (with the
engine cool).
10. If necessary, add a50/50 mixtureof engine
coolant and distilled water to the engine coolant
reservoir until the coolant level is at the“cold fill
level”as listed on the reservoir.
After any coolant has been added, check the coolant
concentration see Checking Engine Coolant section).

If the concentration is not 50/50 (protection to
–34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and
additions to obtain a 50/50 coolant concentration.
Whenever coolant has been added, the coolant level
in the coolant reservoir should be checked the next
few times you drive the vehicle. If necessary, add
enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper
level.
If you have to add more than 1.0 liter (1.0 quart) of
engine coolant per month, have your dealer check
the engine cooling system. Your cooling system may
have a leak. Operating an engine with a low level of
coolant can result in engine overheating and possible
engine damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use
of recycled engine coolant in vehicles originally
equipped with Motorcraft Premium Gold Engine
Coolant since a Ford-approved recycling process is
not yet available.
Used engine coolant should be disposed of in
an appropriate 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 this
chapter.
Fill your engine coolant reservoir as outlined in
Adding engine coolantin 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%.
