Air Cleaner: Renewing Filter Element And Cleaning Housing - Audi A8 2010 Maintenance Manual

Note
The refractometer - T10007 A- must be used to determine the
♦
current anti-freeze concentration.
Scale -1- on the refractometer applies to coolant additives
♦
G11, G12, G12+ and G12++.
Scale -2- refers only to coolant additive G13.
♦
If more than one type of coolant additive has been used: Al‐
♦
ways use the scale for G13 to determine the anti-freeze pro‐
tection.
The temperature indicated on the refractometer - T10007 A-
♦
corresponds to the temperature at which the first ice crystals
can form in the coolant.
It is essential that anti-freeze be used in the cooling system all
♦
year round. In the correct concentration, coolant additives pre‐
vent scaling and frost and corrosion damage, and also raise
the boiling point of the coolant.
♦ Because of its high boiling point, the coolant improves engine
reliability under heavy loads in countries with tropical climates.
3.49.2 Filling up coolant
Table of test values and procedure guidelines:
Frost protection to:
-25 °C

Procedure:
– Add required amount (using mixture ratio according to anti-
freeze protection specification in Maintenance table). Use the
table as a reference for the coolant mixture ratio.
Note
Small quantities of coolant can simply be topped up. Use the
cooling system charge unit - VAS 6096- to add larger quantities
of coolant.
