Checking The Coolant Level And Adding Coolant - Porsche cayman gt4 Owner's Manual

Checking the Coolant Level and
Adding Coolant
The coolant provides year-round protection from
corrosion and freezing down to –35 °F (–37 °C).
Regular checking of the coolant level is part of
servicing. The coolant level only needs to be
checked when a warning message appears on the
multi-function display in the instrument panel.

coolant
Coolant is hazardous to health. Coolant can be
deadly to children or pets if consumed.

Also, keep coolant away from your pets. They
can be attracted to it should there be a spill, or
to used coolant left in an open container.
h
Hot engine coolant
WARNING
The coolant becomes very hot when the engine is
running and can burn you.
The coolant reservoir is pressurized. Careless
opening of the coolant reservoir can lead to hot
coolant suddenly spraying out.

Do not open the cap on the reservoir when the
engine is hot.
f
Allow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.

Checking the coolant level when a warning
message appears on the multi-function display in
the instrument panel:
1. Allow the engine to cool as far as possible.
2. Turn cap anti-clockwise and remove.
3. Cover the reservoir cap with a cloth.
Open reservoir cap carefully and allow any
overpressure to escape.
Finally, unscrew reservoir cap completely.
4. Reading off the engine coolant level:
When the engine is cold and the vehicle is
level, the coolant level indicator C must be
between MIN and MAX markings.
5. Top up with coolant if necessary.
Only add a mixture of antifreeze and distilled
water in equal parts.
Antifreeze in coolant:
50 % provides antifreeze protection down
to –35 °F (–37 °C).
The maximum fill level is reached when the
coolant level indicator C is at the MAX marking.
Do not exceed the MAX-mark when topping up.
6. Screw the cap on the reservoir closed until it
locks securely.
7. Fit cap and turn it clockwise.
8. Have the cooling system checked.
Please contact an authorized Porsche dealer.
Information
If pure water is added in an emergency, the mixing
ratio will have to be corrected.
A significant loss of coolant indicates a leak in the
cooling system.
f
The cause must be eliminated without delay.
Please contact an authorized Porsche dealer.
