Danger!

Risk of injury to skin and eyes from scalding due to contact with hot coolant spray.
Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage bottles.

Wear protective gloves, protective clothing and eye protection.

1

Open cooling system cap (2) at coolant expansion reservoir (1)

Turn cooling system cap carefully as far as the first detent and release pressure

2

Fit suitable hoses (4, 6) onto radiator and crankcase, open drain plugs (3, 5) at radiator and at crankcase and drain coolant

Collect coolant

Disposing of coolant

Pay attention to legal provisions or local wastewater regulations!

Refer to Environmental Protection Catalog issued by MBVD/PWU for locations in Germany.
