•Note:Do not add extra inhibitors or additives to the coolant. These
can be harmful and compromise the corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specificationsfor more information. 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 prediluted
coolant to bring the coolant level to the proper level and concentration.
Coolant 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 prediluted coolant to the coolant reservoir until the coolant
level is between the MIN and MAX marks on the reservoir.
3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper radiator hose is warm (this
indicates that 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 prediluted coolant to the coolant reservoir until the coolant level
is between the MIN and MAX marks 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 prediluted coolant to the coolant reservoir until the
coolant level is between the MIN and MAX marks on the reservoir.
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 prediluted coolant to bring the coolant to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of coolant per month,
have your dealer check the 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.
