Adding coolant
When adding coolant, make sure it is a 50/50 mixture of coolant and
distilled water. Add the mixture to the coolant reservoir(s),when the
engine is cool, until the appropriate fill level is obtained.
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.
Note:If coolant is added to bring the level within the COLD FILL
RANGE when the engine is not cold, the system will remain underfilled.
WARNING:Do not add coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
WARNING:Do not put coolant in the windshield washer fluid
container. If sprayed on the windshield, coolant could make it
difficult to see through the windshield.
•Do not mix coolants. Add the coolant type originally equipped
in your vehicle.Refer toMaintenance product specifications and
capacitiesin this chapter for the proper coolant type.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
•A large amount of water without engine coolant may be added to the
engine cooling system only, in case of emergency, to reach a vehicle
service location. Avoid this procedure if delivery to the service location
requires heavy engine loads. In this instance, the cooling system(s)
must be drained, chemically cleaned with MotorcraftEngine Cooling
System Iron Cleaner, and refilled with a 50/50 mixture of coolant and
distilled water as soon as possible. Water alone (without coolant) can
cause damage from corrosion, overheating or freezing.DO NOTuse
this method for the secondary cooling system. The secondary cooling
system operates close to ambient temperature, and is susceptible to
freezing in any subfreezing environment, in the absence of coolant.
•
Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol and
other liquids can cause engine damage from overheating or freezing.

SPECIAL OPERATING CONDITIONS
Frequent or extended idling (over 10 minutes per hour of normal driving)
As required– Change engine oil and replace oil filter as indicated by
message center and perform services as listed in the
Scheduled Maintenance chart.
Every 15,000 miles (24,000 km),
6 months, 600 hours of engine
operation, or as indicated by the
message center or instrument
cluster (whichever occurs first)– Change engine- and frame-mounted fuel filters
Every 15,000 miles (24,000 km) or
800 hours of engine operation
(whichever comes first)– Inspect concentration (freeze-point protection) and
additive strength (corrosion inhibitor) (add engine coolant
additive, if required). Refer to
Engine cooling systemin
theIntroductionchapter.
Every 60,000 miles (96,000 km) or
2400 hours of engine operation
(whichever comes first)– Flush & refill engine coolant (refer to
Engine Coolant
Change Record)– Do not add engine coolant additive
Perform the services noted in the preceding table at the specified
time/mileage (km) period either within 3,000 miles (5,000 km) of the
OIL CHANGE REQUIRED message appearing in the message center or
when the time/mileage (km) reading indicates service is due.
Example #1:The OIL CHANGE REQUIRED message comes on at
18,751 miles (30,177 km); perform the 22,500 mile (36,000 km) fuel
filter replacement.
Example #2:The OIL CHANGE REQUIRED message hasnotcome on
but the odometer reads 22,500 miles (36,000 km); perform the fuel filter
replacement. (i.e., Intelligent Oil Life Monitor™ was reset at 15,000 miles
[24,000 km].)
Note:For vehicles that operate under severe service conditions such as
frequent or extended idle (over 10 minutes per hour of normal driving),
maintenance requirements need to be adjusted. This needs to be
considered when determining vehicle service intervals.
Note:When adding supplemental coolant additive, do not exceed the
specified maximum of 48 fl. oz. (1.4L). Operating the engine with
excessive supplemental coolant additive may cause overheating which
could lead to severe permanent engine damage.
