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.
