FAIL-SAFE COOLING - 3.5L
DURATEC/3.5L ECOBOOST
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs due to
overheating.
The fail-safe distance depends on outside
temperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLING
WORK
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine.
Note: Have your vehicle checked as soon
as possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODE
IS ACTIVATED
WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
2022 Transit (TTH) Canada/United States of America, NK3J 19A321 AA enUSA, Edition date: 202107, First-Printing
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside
assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait for a short
period of time for the engine to cool.
