Draining

• ‒ Remove cap from coolant expansion tank.
• ‒ Remove drain screw from coolant pipe , item 25

Note:

Observe disposal regulations!

Filling

Notes:

• ◆ Only use coolant additive G 12 in accordance with TL VW 774 F.
  Distinguishing feature: coloured violet
• ◆ G 12 and coolant additives marked "In accordance with TL VW 774 F" prevent frost and corrosion damage, scaling and also raise boiling point of coolant. For this reason the system must be filled all year round with frost and corrosion protection additives.
• ◆ G 12 violet (in accordance with TL VW 774 F) can be mixed with the previous coolant additives G 11 and G 12 red!
• ◆ If radiator, heat exchanger, cylinder head or cylinder head gasket is replaced, do not reuse old coolant.
• ◆ For filling coolant circuit the cooling system charging unit VAS 6096 is recommended.

Recommended mixture ratios:

     1)     The amount of anti-freeze must not exceed 60 %; frost protection and cooling effect will decrease if amount of anti-freeze is too high.

     2)     The quantity of coolant can vary depending upon the vehicle equipment.

• ‒ → Insert drain screw on coolant pipe again -arrow-.

With cooling system charging unit VAS 6096

• ‒ Screw adapter V.A.G 1274/3 onto expansion tank.
• ‒ Fill coolant circuit using cooling system charging unit VAS 6096.

=> Operating instructions for cooling system charging unit VAS 6096

Not using cooling system charging unit VAS 6096

• ‒ Press top radiator hose down.

• ‒ → Fill with coolant up to max. mark on expansion tank.
• ‒ Start engine and run at idling speed and at the same time fill with coolant up to over-flow hole on expansion tank.
• ‒ Fit expansion tank cap.
• ‒ Run engine until radiator fan cuts-in.
• ‒ Check coolant level and replenish as necessary. When the engine is at normal operating temperature, the coolant level must be on the max. mark, when the engine is cold, between the min. and max. marks.
