engine coolant AUDI R8 COUPE 2020 User Guide

Checking and Filling


— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
o Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.

and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Add coolant in the correct mixture ratio
=> page 236 until the dipstick is no more than
0.39
in (1 cm) above the edge of the coolant
expansion tank.

Add more coolant if necessary.

Checking and Filling

> Tighten the cap @ again.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

ing from the engine compartment. This in-
creases the risk of burns. The cooling system

or hear steam or coolant escaping, you may
open the engine compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.

ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
