Checking coolant corrosion inhibitor additive strength
At specific mileage intervals of 15,000 miles (24,000 km), as listed in the
scheduled maintenance information
chapter, the coolant corrosion
inhibitor additive should be checked. The optional information display, if
equipped, will also display the message
CHECK COOLANT ADDITIVE
at this time. The purpose of checking is to verify the correct engine
coolant concentration (freeze point protection) and corrosion inhibitor
additive level (strength) of the coolant for maximum engine performance
and protection. Three products are available for ensuring the life and
health of the coolant: one tool, a test kit and a coolant inhibitor additive:
•
Rotunda tool 300–ROB75240 available from your dealer –
recommended refractometer to test coolant concentration.
•
Rotunda 328-R071–ELC (Antifreeze Coolant ELC Contamination Kit) –
Evaluates the corrosion inhibitor additive strength. Note the first step is
to verify the vehicle’s coolant concentration is in the correct range of 40
– 60%. Coolant concentrations outside this range will not provide valid
test results. If the report results in a pass (i.e., the cooling system does
not show excessive contamination/the corrosion inhibitor additive
strength is sufficient), no action is required. If the report results as
insufficient (does not pass), the corrosion inhibitor additive strength of
the coolant is too low. If the ENGINE COOLING SYSTEM corrosion
inhibitor additive strength is low, add 48 fluid oz. of Motorcraft®
Specialty Orange Engine Coolant Revitalizer. If the SECONDARY
COOLING SYSTEM corrosion inhibitor additive strength is low, add 16
fluid oz. of Motorcraft® Specialty Orange Engine Coolant Revitalizer.
•
Motorcraft® Specialty Orange Engine Coolant Revitalizer – Additive to
boost the corrosion inhibitor level based upon the test results of the
Antifreeze Coolant ELC Contamination Kit. The Revitalizer may be
added two times over the life of the coolant. If additional dosages are
required, the cooling system must be flushed and refilled per the
instructions in the Workshop Manual.
Refer to the
Capacities and Specifications
chapter for the proper
coolant and additive specifications.
Coolant change
At specific mileage intervals, as listed in the
scheduled maintenance
information,
the coolant should be changed. The optional information
display, if equipped, will also display the message
COOLANT CHANGE
REQUIRED
at this time.
Refer to the
Capacities and Specifications
chapter for the proper coolant.
