radiator FORD MUSTANG 2001 4.G Owners Manual

²Do not add extra inhibitors or additives to
the coolant.These can be harmful and
compromise the corrosion protection of the
engine coolant.
²Do not mix with recycled coolant unless from
a Ford-approved recycling process (seeUse of
Recycled Engine Coolantsection).
If equipped with the 3.8L V6 engine, to
avoid scalding hot steam or coolant from
being released from the engine cooling system,
never remove the radiator cap from the radiator
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 equipped with the 4.6L V8 engine, to
avoid scalding hot steam or coolant from
being released from the engine cooling system,
never remove the pressure relief cap from the
engine coolant reservoir 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 pressure relief cap or
radiator cap (depending upon engine application),
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.

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.
