DSG-423 COOLING SYSTEM
05-2
CAUTIONS & WARNINGS
WARNING: THE RADIATOR OR DEGAS TANK IS
EQUIPPED WITH A PRESSURE CAP. IT IS
DANGEROUS TO REMOVE THIS WHEN THE
SYSTEM IS VERY HOT.
WARNING: NEVER REMOVE THE PRESSURE
RELIEF CAP WHILE THE ENGINE IS OPERATING
OR WHEN THE COOLING SYSTEM IS HOT. MAY
CAUSE PERSONAL INJURY OR DAMAGE TO
COOLING SYSTEM OR ENGINE. TO REDUCE THE
RISK OF HAVING SCALDING HOT COOLANT OR
STEAM BLOW OUT OF THE DEGAS BOTTLE WHEN
REMOVING THE PRESSURE RELIEF CAP, WAIT
UNTIL THE ENGINE HAS COOLED DOWN TO AT
LEAST 40°C (110°F).
1. Wrap a thick cloth around the pressure relief cap and
turn it slowly one-half turn counterclockwise.
Stepping back while the pressure is released from
the cooling system.
2. When you are sure all the pressure has been
released, (still with a cloth) turn counterclockwise
and remove the pressure relief cap.
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.
CAUTION: Under no circumstances should the en-
gine be started without liquid in the cooling system.
This may cause permanent damage to the engine.
CAUTION: The use of straight water as a coolant
will cause permanent damage to the engine.
CAUTION: Never use a cold coolant mixture to top-
up the radiator or degas tank of a hot engine if the
coolant level is very low; this could cause serious
engine damage.
CAUTION: In territories where freezing conditions
may occur, the coolant should consist of a mixture
of 50% plain water and 50% Motorcraft Premium
Gold coolant, or equivalent. This antifreeze con-
tains additional corrosion inhibitors designed to
provide lasting protection for the engine.
CAUTION: Only this antifreeze, or proprietary anti-
freeze meeting Ford specification WSS-M97B51-A1
should be used when topping-up or re-filling the
cooling system. Do not mix coolant types.
CAUTION: Do not add or mix an orange-colored ex-
tended life coolant, such as Motorcraft Specialty Or-
ange engine coolant with factory filled coolant
WSS-M97B44-D. Mixing Motorcraft Specialty Or-
ange engine coolant or any orange colored extend-
ed life product, with factory filled coolant, can result
in degraded corrosion protection.
CAUTION: If there is engine coolant in the engine oil
or transmission fluid, the cause must be corrected
and oil/fluid changed or major component damage
can occur.
CAUTION: When removing coolant, the coolant
must be recovered in a suitable, clean container for
reuse. If the coolant is contaminated, it must be re-
cycled or disposed of correctly.
WARNING: DO NOT STAND INLINE WITH OR NEAR
THE ENGINE COOLING FAN BLADE WHEN
REVVING THE ENGINE. FAILURE TO FOLLOW
THESE INSTRUCTIONS MAY RESULT IN
PERSONAL INJURY.
CAUTION: Under no circumstances should the
drive belt, tensioner or pulleys be lubricated as po-
tential damage to the belt material and tensioner
dampening mechanism will occur. Do not apply any
fluids or belt dressing to the drive belt or pulleys.
