Checking Engine Coolant; Checking Motor/Electronics (M/E) Coolant - Ford Fusion Hybrid Owner's Manual

Maintenance and Specifications

Checking engine coolant

The concentration and level of
engine coolant should be checked at
the intervals listed in scheduled
maintenance information. The
coolant concentration should be
maintained at 50/50 coolant and
distilled water. For best results,
coolant concentration should be
tested with a refractometer such as
Rotunda tool 300-ROB75240E
available from your dealer. Ford
does not recommend the use of
hydrometers or coolant test strips
for measuring coolant
concentration.The level of coolant
should be maintained at the FULL COLD level or within the COLD FILL
RANGE in the coolant reservoir. If the level falls below, add coolant per
the instructions in the Adding engine coolant section. When the engine
is cold, check the level of engine coolant in the reservoir.

Checking motor/electronics (M/E) coolant

The M/E coolant reservoir is located
at the rear of the engine
compartment. Refer to the following
engine coolant sections for all
information, instructions and
warnings related to cooling systems.
The two systems use the same
coolant and operate similarly, with
the Motor and Electronics system
generally operating at a lower
temperature and pressure. The fluid
levels in both reservoirs need to be maintained. When the engine is cold,
check the level of M/E coolant in the reservoir. The coolant should be at
the FULL COLD level as shown on the side of the coolant reservoir.
