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 a 50/50 mixture of coolant and distilled water 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. SeeEngine and secondary cooling system
coolantearlier. If the concentration is not 50/50, 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 reservoir should
be checked the next few times you drive the vehicle. If needed, add a
50/50 concentration of coolant and distilled water to the proper level.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.
Coolant additives
At specific mileage intervals of 15,000 miles (24,000 km), as listed in the
scheduled maintenance informationchapter, the coolant additive
should be checked. The optional message center, if equipped, will also
display the messageCHECK COOLANT ADDITIVEat this time. The
purpose of checking is to verify the correct concentration (freeze point
protection) and additive strength (corrosion inhibitor) levels of the
coolant for maximum engine performance and protection. Three
products are available for ensuring the life and health of the coolant: two
test kits and a coolant inhibitor additive:
•Rotunda 328-00007 (Matthew’s Water CoolCheck) – Evaluates water
quality (hardness, chloride, and pH) for 50/50 mixture of coolant and
distilled water. Use distilled water. If distilled water is unavailable,

Multi-point inspection
In order to keep your vehicle running right, it is important that you have
the systems on your vehicle checked regularly. This can help identify any
potential issue before there are any problems. Ford Motor Company
suggests the following multi-point inspection to be performed at every
scheduled maintenance interval as the way to ensure your vehicle keeps
running right.
