the washer -arrow-, and simultaneously check its radial move‐

ment with light pressure of your index applied on a screwdriv‐

er.

– Never turn -arrows- or leverage the screwdriver.

WARNING

The screwdriver should touch only the washer and never the

Suspension arm joints - visual inspec‐

tion

– Check the sealing bellows in the suspension arm joints

-arrow- for damage and leaks.

4.30

Cooling system - check the antifreeze

additive and the coolant level

Note

♦

All engines are supplied with radiator antifreeze additive and

anti-corrosion G 12 - according to TL VW 774 F (lilac color).

Make sure that only G 12 is replenished.

♦

Do not mix with the G 11 antifreeze additive, blue or green

colors.

WARNING

The coolant additive G 12 cannot be mixed with other additives.

When they are mixed, severe damage is caused to the engine.

If a mix is detected (brown color), the coolant must be imme‐

diately replaced (repair measure).

Note

♦

The G 12 as permanent filling (does not require replacement)

is adequate for cast iron and aluminum engines, and protects

the engine against freezing, damage from corrosion, lime‐

stone build-up and overheating.

♦

The G 12 raises the boiling point to 275°F and provides better

heat dissipation.

♦

The coolant ratio must be at least 40% (antifreeze protection

to - 77ºF) and it must not exceed 60% (antifreeze protection

to - 104ºF), otherwise the antifreeze protection is reduced and

also the cooling operation is worsened.

4.30.1

Check the antifreeze protection and re‐

plenish the cooling system, if necessary
