4.4 Filling with coolant
Caution
If large components (e.g. engine, radiator etc.) are to be re‐
moved/installed, it is absolutely necessary to drain the cooling
system ⇒ page 155 . Otherwise, hidden air bubbles can result
in incorrect filling. This results in temperature problems in the
cooling system and heating circuit.
Special tools and workshop equipment required
♦ Coolant system charge unit - VAS 6096-
♦ Adapter for cooling system tester - V.A.G 1274/8-
♦ Refractometer - T10007 A-
Caution
Use only distilled water for mixing coolant additives. The use
of distilled water ensures optimum protection against corro‐
sion.
