What you should know about
fail-safe cooling
Vehicles equipped with 4.6L, and
5.4L engines have a fail-safe
cooling mode. If the engine coolant
supply is depleted, this feature
allows the vehicle to be driven
temporarily before incremental
component damage is incurred.
The “fail safe” distance depends on
ambient temperatures, vehicle load
and terrain.
When fail-safe mode is
activated
•
Pull off the road as soon as
possible.
•
Immediately turn the engine off
to prevent severe engine
damage.
•
Wait for the engine to cool.
•
Check the coolant level.
