♦ Inspection service: Coolant level above “MIN. marking”

-arrow-.

– If coolant level is too low, replenish required amount according

to mixture ratio.

Note

If fluid loss is greater than can be expected through normal use,

determine source and rectify (repair measure).

Note

Coolant additive G12 Plus Plus according to TL VW 774 G

prevents frost and corrosion damage, scaling and also raises

boiling point of coolant. For these reasons, the cooling system

must be filled all-year-round with a frost and corrosion protec‐

tion additive.

Because of its high boiling point, the coolant improves engine

reliability under heavy loads, particularly in countries with trop‐

ical climates.

The coolant concentration must not be reduced by adding wa‐

ter even in warmer seasons and in warmer countries. The anti-

freeze portion must be at least 40 %.
