Cooling system (engines 1.4 l)
* use only antifreeze 19 40 656/ 90 297 545 (blue) up to my 2001 and only antifreeze 19 40 650/ 09 194 431 (red) since my 2001 in 50% mixture with water.
** at 20°c/68°f coolant temperature.
Cooling system (engines 1.6 l)
* use only antifreeze 19 40 650/ 09 194 431 (red) in 50% mixture with water.
** at a coolant temperature of 20°c.
Cooling system (1.8 l engines)
* use only antifreeze 19 40 656/ 90 297 545 (blue) up to my 2001 and only antifreeze 19 40 650/ 09 194 431 (red) since my 2001 in 50% mixture with water.
** at coolant temperature 20°c / 68°f.
Examination
Always use antifreeze 1940650/ 9194431 (red). Make sure the concentration is: 50% water and 50% antifreeze. Antifreeze not only protects the entire cooling system from freezing, but also protects all coolant-flushed parts from deposits and corrosion.
Water quality also plays an important role. Potable water usually meets these requirements.
The engine can be damaged if non-recommended antifreeze is used.
If the radiator, cylinder head or cylinder head gasket has been replaced, the old coolant must not be reused.
Attention! When changing the coolant on vehicles with air conditioning: turn off the air conditioner and set the ECO mode.
Open the cooling system.
Attention! The cooling system is under pressure.
Turn away a cover of a broad tank of a cooling liquid.
Fill in cooling liquid up to the bottom mark of a broad tank of a cooling liquid.
Close the cooling system.
Screw on the coolant expansion tank cap.
Let the engine warm up at 2500 min-1 before turning on the radiator fan.
Remove air from the cooling system.
Let the engine run for approximately 2 minutes at 2000-2500 minutes-1.
Note. The air from the cooling system is removed through the exhaust lines.
Stop the engine and let it cool down.
Check the coolant level and add coolant to the mark «COOL».
