When the engine is cold, check the
level of the engine coolant in the
reservoir.
•
The engine coolant should be at the “cold fill level” or within the “cold
fill range” as listed on the engine coolant reservoir (depending upon
application).
•
Refer to the Scheduled Maintenance Guide for service interval
schedules.
•
Be sure to read and understand
Precautions when servicing your
vehicle
in this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer to
Adding
engine coolant
in this chapter.
Note:
Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Vehicles with diesel engines typically are used to carry heavy loads and
accumulate mileage rapidly. These two factors cause the additives in the
coolant to “wear out” in a shorter time. Ford recommends an interim
service interval performed at 12 months or 24 000 km (15 000 miles),
whichever occurs first. Add 237–295 ml (8–10 oz.) of supplemental
coolant additive FW-16 to the cooling system. For vehicles with extensive
idling time, add 237–295 ml (8–10 oz.) of coolant additive FW-16 after
every 500 hours of operation. (see scheduled maintenance guide)
Adding engine coolant — 7.3L Power Stroke
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,
when the
engine is cool
, until the appropriate fill level is obtained.
