coolant reservoir VOLKSWAGEN PASSAT CC 2015 1.G Owners Manual

When adding engine coolant, use a mixture of distilled water and at
least 40% coolant additive G 13 or G 12 plus-plus (TL-VW 774 G) for
optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant addi-
tives together significantly reduces corrosion protection ⇒  and can
lead to engine damage that is not covered by any Volkswagen Lim-
ited Warranty.
WARNING
Too little antifreeze protection in the engine cooling system can
cause engine failure and severe injuries.
Always make sure there is enough of the correct coolant ad-
ditive to provide proper antifreeze protection at the coldest
temperatures that can be expected where the vehicle will be
used.
At extremely cold temperatures, the coolant could freeze,
causing the vehicle to break down. The heater would also not
work, and vehicle occupants could be without protection at
subfreezing temperatures.
NOTICE
Never mix original Volkswagen engine coolant additives with
other additives not approved by Volkswagen. Mixing
Volkswagen coolant additives with coolant additives made by
other manufacturers can seriously damage the engine and the
engine cooling system.
If the fluid in the engine coolant reservoir is any color but pink,
then G 13 was mixed with a different engine coolant. If this is the
case, the engine coolant must be replaced immediately. Other-
wise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the envi-
ronment. Collect leaking operating fluids and dispose of them proper-
ly in accordance with applicable environmental laws and regulations.

Checking engine coolant level
When the engine is cold, check the engine coolant level relative to
the marking on the side of the expansion tank ⇒ fig. 168.
If the coolant level in the tank is below the minimum mark (“min”),
add coolant. When the engine is warm, the engine coolant level may
be slightly above the upper edge of the marked range.
Adding engine coolant
Always protect face, hands and arms from hot escaping coolant or
steam by covering the cap with a large, thick rag.
Carefully unscrew the cap ⇒ .
Add only new engine coolant according to Volkswagen specifica-
tions (⇒ Engine coolant specifications) ⇒ .
The engine coolant level must be inside the marks on the side of
the reservoir ⇒ fig. 168. Do not fill above the top edge of the filling
range! ⇒ 
Screw the lid tightly.
Even in an emergency, do not use any other kind of coolant addi-
tive if engine coolant meeting Volkswagen specifications (⇒ page 456,
Engine coolant specifications) is unavailable! Instead, add distilled
water only ⇒ . As soon as possible, have the correct coolant ratio
restored using engine coolant that meets Volkswagen specifications
⇒  Engine coolant specifications.

failure. If you have added non-distilled water, take the vehicle
immediately to an authorized Volkswagen dealer or an author-
ized Volkswagen Service Facility to have the coolant system
drained, flushed, and refilled completely with the proper coolant.
Refill engine coolant only up to the top edge of the marked fill
range ⇒ fig. 168. Excess engine coolant may be forced out of the
engine cooling system when it gets hot and cause damage.
In the case of significant engine coolant loss, refill engine
coolant only when the engine is completely cooled down. Signif-
icant engine coolant loss is a sign of leaks in the cooling sys-
tem. Have the engine cooling system checked immediately by an
authorized Volkswagen dealer or an authorized Volkswagen Ser-
vice Facility. Otherwise the engine may be damaged!
When changing or topping off operating fluids, make sure that
you pour the fluids into the correct reservoirs. Serious malfunc-
tions and engine damage can result if you pour operating fluids
into the wrong reservoir.

WARNING
Improper use of operating fluids and equipment can cause ac-
cidents, serious personal injuries, burns and/or poisoning.
Always store vehicle care products in a safe place in original
containers that are securely closed.
To reduce the risk of poisoning, never use empty food or
beverage containers that might mislead someone into drinking
from them.
Always keep vehicle care products out of the reach of chil-
dren.
Always read and heed all the instructions and all WARNINGS
on the package before using vehicle care products.
When using products that give off harmful fumes, always
work outdoors or in a well ventilated area.
Never use fuel, turpentine, engine oil, nail polish remover or
other volatile fluids for vehicle care. They are poisonous and
highly flammable. They could cause fires and explosions!
NOTICE
Only refill with suitable operating fluids. When changing or
topping off fluids, make sure that you pour the fluids into the
correct reservoirs. Adding incorrect fluids will cause serious
malfunctions and engine damage! Under no circumstances
should you mix up operating fluids. Otherwise serious malfunc-
tions and engine damage can occur!
Accessories and other things installed in front of the cooling
air intakes impair the efficiency of the engine coolant. The en-
gine can overheat under high outside temperatures or under
high engine loads!
Leaking operating fluids can pollute the environment. Collect
leaking operating fluids in suitable containers and dispose of them
properly in accordance with applicable environmental laws and regu-
lations.
