If you have to add more than 1.0 quart (1.0
liter) of engine coolant per month, have
your authorized 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.
Engine and Secondary Cooling
System Refill Procedure
The following procedure should be used
when refilling the engine or secondary
cooling systems after it has been drained
or become extremely low.
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.
5. Slowly add prediluted engine coolant
to the coolant reservoir until the
coolant level is within the COLD FILL
RANGE as listed on the reservoir.
6. Reinstall the pressure relief cap.
7.
Start and run the engine at 2000 rpm
for 2 minutes.
8. Shut engine off, and remove the
pressure relief cap as previously
outlined.
9. If required, add prediluted engine
coolant to the coolant reservoir until
the coolant level is within the COLD
FILL RANGE as listed on the reservoir.
10.
Engine cooling system:
Repeat
Step 5 until the coolant level has
stabilized (is no longer dropping after
each step) AND the upper radiator
hose at the radiator is warm to the
touch (indicating that the engine
thermostat is open and coolant is
flowing through the radiator).
Secondary cooling system:
Repeat
Step 5 until the coolant level has
stabilized (is no longer dropping after
each step) AND the lower passenger
side of the secondary radiator is
warm to the touch (indicating
secondary thermostat is open and
coolant is flowing through the entire
system).
11.
Reinstall the pressure relief cap. Shut
the engine off and let it cool.
12.
Check the coolant level in the
reservoir before you drive your vehicle
the next few times (with the engine
cool).
13.
If necessary, add prediluted engine
coolant to the coolant reservoir until
the coolant level is within the COLD
FILL RANGE as listed on the reservoir.
After any coolant has been added,
check the coolant concentration. See
Adding Engine Coolant
earlier in
the chapter for more information.
Whenever coolant has been added, the
coolant level in the reservoir should be
checked the next few times you drive the
vehicle. If needed, add prediluted engine
coolant to bring the coolant level to the
proper level on the reservoir.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
