counterclockwise and remove the pressure relief cap.
In territories where freezing conditions may occur, the coolant should consist of a
mixture of 50% plain water and 50% Motorcraft Super Plus 2000 coolant. This
antifreeze contains additional corrosion inhibitors designed to provide lasting
protection for the engine.
Only this antifreeze, or proprietary antifreeze meeting Ford specification WSS-
M97B44-D or Ford specification ESE-M97B44-A should be used when topping-up
or re-filling the cooling system.
Motorcraft Super Plus 2000 coolant has long life characteristics and if the
concentration is kept to a maximum of 50% it will provide adequate frost protection
and inhibiting for the life of the engine.
NOTE: If a major component of the cooling system is renewed such as the
radiator, water pump etc., the system should be flushed and re-filled with a 50%
solution of Motorcraft Super Plus 2000 coolant and clean water.
In territories where the ambient temperature is such that no protection against
freezing is required, it is recommended that a 25% concentration of Motorcraft
Super Plus 2000 coolant is used. This will protect water pumps, core plugs,
thermostat housings and radiators against corrosion for the life of the engine and
raise boiling point when used at this concentration. See previous Note on renewing
cooling system components.
The antifreeze concentration in a cooling system can be determined by using a
suitable hydrometer.
A reading of 1080 represents a 50% antifreeze concentration.
A reading of 1040 represents a 25% antifreeze concentration.
A reading of 1000 represents plain water.
WARNING: ANTIFREEZE CONTAINS MONO ETHYLENE GLYCOL AND
OTHER CONSTITUENTS WHICH ARE TOXIC IF TAKEN INTERNALLY AND
CAN BE ABSORBED IN TOXIC AMOUNTS ON REPEATED OR PROLONGED
SKIN CONTACT. PERSONS USING ANTIFREEZE ARE RECOMMENDED TO
ADHERE TO THE FOLLOWING PRECAUTIONS:
ANTIFREEZE MUST NEVER BE TAKEN INTERNALLY. IF ANTIFREEZE IS
SWALLOWED ACCIDENTALLY, MEDICAL ADVICE SHOULD BE SOUGHT
IMMEDIATELY.
PRECAUTIONS SHOULD BE TAKEN TO AVOID SKIN CONTACT WITH
ANTIFREEZE. IN THE EVENT OF ACCIDENTAL SPILLAGE ONTO THE
SKIN, ANTIFREEZE SHOULD BE WASHED OFF AS SOON AS
PRACTICABLE. IF CLOTHING IS SPLASHED WITH ANTIFREEZE, IT
SHOULD BE REMOVED AND WASHED BEFORE BEING WORN AGAIN, TO
AVOID PROLONGED SKIN CONTACT.
FOR REGULAR AND FREQUENT HANDLING OF ANTIFREEZE,
PROTECTIVE CLOTHING (PLASTIC OR RUBBER GLOVES, BOOTS AND
IMPERVIOUS OVERALLS OR APRONS) MUST BE USED TO MINIMIZE
SKIN CONTACT.
