WARNING: When opening the expansion tank, hot steam may come out. to avoid eye injury and scalding, wear protective goggles and protective clothing. Cover the bull's lid with a rag and carefully open it.
Open the cover of the expansion tank of the cooling system. Remove soundproofing.
Pull off the mounting bracket (pic. 2.232) coolant hose down and remove the hose from the radiator.
NOTE: Follow the rules for disposal of coolant.
Additionally, to drain the engine coolant, disconnect the water hose from the oil cooler (pic. 2.233).
Coolant fill
NOTE: Only use G 12 plus as a concentrate according to the norm «TL-VW 774 F». Characteristic feature: lilac color. G 12 plus and coolant additives marked: «corresponds to TL-VW 774 F» prevents frost and corrosion damage, lime deposits and raises the boiling point. Therefore, throughout the year, the cooling system must necessarily work with an antifreeze and anti-corrosion concentrate. Especially in countries with a tropical climate, at high engine loads, a coolant with a high boiling point reliably protects the engine during operation.
The freezing point of the coolant must be at least -25°C (in countries with an arctic climate - not less than -35°С).
It is also forbidden to reduce the proportion of concentrate in the coolant in the warm season or when operating in countries with a warm climate by adding water to the cooling system. The share of concentrate should be at least 40%.
If, due to climatic conditions, the freezing point must be lowered, the proportion of G 12 plus concentrate can be increased, but not more than 60% (freezing temperature in this case will be about -40°C). If this limit is exceeded, the freezing point will rise again and, in addition, the heat capacity of the coolant will decrease.
When replacing the radiator, heater heat exchanger, water pump or cylinder head gasket, the drained coolant must not be reused.
To determine the freezing point of the coolant, it is recommended to use the T10007 refractometer.
Recommended Mixing Ratios
Freezing point up to | Share of concentrate | 012 | Veda |
-25°C | 40% | 4.0 l | 5.0 l |
-35°C | 50% | 4.5 l | 4.5 l |
The amount of coolant to be filled may vary depending on the vehicle equipment.
Work order
Install the cooling system hoses and secure them.
Screw the adapter VAG 1274/8 to the expansion tank (pic. 2.234).
Top up the coolant using the cooling system filler VAS 6096.
