Maintenance WARNING: To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. 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. Coolant and Intercooler Refill Procedure The following procedure should be used when refilling the cooling system after it has been drained or become extremely low. 1. Remove the pressure relief cap from the coolant reservoir as previously outlined. 2. Slowly add a 50/50 mixture of coolant and distilled water to the 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 coolant reservoir as previously outlined. 7. Add a 50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is at the "cold fill range" 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 a 50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is at the "cold fill range" as listed on the reservoir. 26 2011 05+ Mustang (197) Supplement, 1st Printing USA (fus)

WARNING:
To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
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.
Coolant and Intercooler Refill Procedure
The following procedure should be used when refilling the cooling
system after it has been drained or become extremely low.
1. Remove the pressure relief cap from the coolant reservoir as
previously outlined.
2. Slowly add a
50/50 mixture
of coolant and distilled water to the
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 coolant reservoir as
previously outlined.
7. Add a
50/50 mixture
of coolant and distilled water to the coolant
reservoir until the coolant level is at the “cold fill range” 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 a
50/50 mixture
of coolant and distilled water to
the coolant reservoir until the coolant level is at the “cold fill range” as
listed on the reservoir.
