Using the Engine Block Heater
(If equipped)
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10˚F (-23˚C) or below. An engine block heater
warms the engine coolant, which improves
starting, warms up the engine faster, and allows
the heater-defrost system to respond quickly.
To turn the heater on, simply plug it into a
grounded 110-volt outlet. Ford recommends that
you use a 110-volt circuit that is protected by a
ground fault circuit interrupter.
To prevent electrical shock, do not use
your heater with ungrounded electrical
systems or two-pronged (cheater) adapters.
For best results, plug the heater in at least three
hours before you start your vehicle. Using the
heater for longer than three hours will not
damage the engine, so you can plug it in at
night to start your vehicle the following
morning.
If the Engine Cranks but Does
Not Start or Does Not Start After
a Collision
Fuel Pump Shut-Off Switch
If the engine cranks but does not start or does
not start after a collision, the fuel pump shut-off
switch may have been triggered. The shut-off
switch is a device intended to stop the fuel
pump when your vehicle has been involved in a
major jolt.
