Note. If large quantities of metal shavings or abraded material are found in the engine oil while servicing the engine, the oil passages must be carefully cleaned to prevent resulting damage and the engine oil cooler must be replaced. The oil level must not be above the max. mark - danger of damage to catalytic converter!

Note. Drained coolant must be stored in a clean container for disposal or reuse.

1. Remove cover above coolant reservoir - arrows -.

1. Open cap of coolant expansion tank.

1. For vehicles with auxiliary heater, remove bolts - arrows - for exhaust pipe of auxiliary heater on sound insulation.

1. Loosen quick-release fasteners - 1 - and remove front sound insulation.

1. Place drip tray V.A.G 1306 or drip tray VAS 6208 under engine.
2. Disconnect coolant hose - arrow - from left coolant pipe and drain coolant.

Scheme 371

1. Remove lower right coolant hose from auxiliary cooler - arrow - and allow remaining coolant to drain.

Filling

Note. The cooling system is filled all year round with a mixture of frost and corrosion protection additives and water. Only coolant additive Plus G 012 A8F A1 (short: G12+) "according to TL VW 774 F" may be used. Other coolant additives may reduce the corrosion protection effect significantly. The damage resulting from this may lead to loss of coolant and consequently to severe engine damage. Coolant additive G12+ can be combined with additives G11 and G12. G12+ and coolant additives with the designation "according to TL VW 774 F" reduce frost and corrosion damage as well as lime deposits. They also raise the boiling point. For this reason the system must be filled all year round with frost and corrosion protection additives. Because of its high boiling point, the coolant improves engine reliability under heavy loads, particularly in countries with tropical climates. Protection against frost must be assured to about -25 C (in arctic climatic countries to about -35 C). The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The coolant additive portion must be at least 40%. If greater frost protection is required for climatic reasons, the amount of G12+ can be increased, but only up to 60% (frost protection to about -40 C), otherwise frost protection and cooling effectiveness will be reduced. Only clean drinking water may be used for mixing coolant. If the radiator, heater core, cylinder head and cylinder head gasket, cylinder block or any of the auxiliary coolers is replaced, completely replace the engine coolant. Dirty coolant must not be reused. For coolant G12+ , use refractometer T10007 to test frost protection in cooling system.

Conditions

1. Ignition switched off.

Work sequence

1. Connect lower right coolant hose to auxiliary cooler - arrow -.

1. Connect lower coolant hose to coolant pipe - arrow -.

Scheme 372

1. Fill replacement reservoir VAS 6096/1 with at least 15 liters of coolant pre-mixed to correct mixture ratio

1. G12+ (40%) and water (60%) for frost protection down to -25 C.
2. G12+ (50%) and water (50%) for frost protection down to -35 C.
3. G12+ (60%) and water (40%) for frost protection down to -40 C.

1. Thread adapter V.A.G 1274/8 onto coolant expansion tank.
2. Assemble cooling system charge unit VAS 6096 on adapter V.A.G 1274/8.
3. Place air outlet hose - 1 - into a small container - 2 -. (A small amount of coolant will come out together with vented air. This drains into container.)
4. Close both valves - A - and - B - by turning lever perpendicular to direction of flow.

1. Connect hose - 3 - to pressurized air.

1. Pressure: 6 to 10 bar positive pressure.

Scheme 373

1. Open valve - B - by turning lever in direction of flow.

A vacuum is created in the cooling system by the suction jet pump.

1. Needle on instrument display must travel into green region.

1. Also briefly open valve - A - by turning lever in direction of flow so that hose of replacement reservoir VAS 6096/1 is filled with coolant.
2. Close valve - A - again.
3. Let valve - B - remain open another 2 minutes.

1. A further vacuum is created in cooling system by suction jet pump.
2. Needle on instrument display must still remain in green region.

1. Close valve - B -.

1. Needle in display instrument must remain in green region, then sufficient vacuum in cooling system is obtained for upcoming filling.

If needle stands below the green region, repeat procedure.

If vacuum decreases, cooling system is leaking.

1. Disconnect pressurized air hose.
2. Open valve - A -.

Vacuum in cooling system has effect of extracting coolant from coolant reservoir VAS 6096/1 ; cooling system is filled.

1. Disconnect cooling system charge unit VAS 6096 from coolant expansion tank.

1. Remove rubber seal - 1 - for plenum chamber covers.
2. Remove plenum chamber cover - 2 -.

Note. Ignore - 3 - in the illustration.

Scheme 374

1. Open bleeder screws - arrows -.
2. Fill up coolant until it escapes from bleeder holes in coolant hoses.
3. Close bleeder screws.
4. Twist cap for expansion tank closed.

1. Make sure that auxiliary heater is switched off.
2. Start engine.
3. Set heating air conditioning system to "HI" on both sides.
4. Let engine run at 2000 RPM for 3 minutes.

1. Let engine run at idle until both large coolant hoses on main cooler are warm.
2. Let engine run at 2000 RPM for 1 minute.
3. Turn off engine and allow it to cool off.

Scheme 375

1. Check coolant level.

1. Coolant level must be at MAX. marking with engine cold.
2. Coolant level may be above MAX. marking with engine at operating temperature.

1. Deactivate vehicle lifting mode --> «43 - SELF LEVELING SUSPENSION»(ref-289219-S16066943732008062700000) .
