AP20.00-I-2010-01B | Correcting anticorrosion/antifreeze concentration | ||
Danger! | Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running | Secure vehicle to prevent it from moving by itself. | |
Danger! | Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by 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 containers. Wear protective gloves, protective clothing and safety glasses. |

Calculation table of refill quantity of
anticorrosion agent and antifreeze
A Determined anticorrosion agent and antifreeze concentration (in % by volume)
B Complete coolant filling capacity (in liters)
C Refill quantity of anticorrosion agent and antifreeze (in liters)
1 Enter determined anticorrosion agent and
antifreeze concentration (A) in the calculation table.
2 Enter complete coolant filling quantity (B) in the calculation table.
3 Calculate refill quantity of anticorrosion agent and antifreeze (C).
4 Remove drain screw on radiator and drain as much coolant as is to be poured in again as refill quantity of anticorrosion agent and antifreeze (C).
5 Screw drain screw into the radiator again, .
6 Pour the calculated refill quantity of anticorrosion agent and antifreeze (C) into the cooling system.
7 Start engine, allow to run at varying speed for approx. one minute and switch off engine.

Example
Determined anticorrosion agent and antifreeze concentration (A): 32 % by volume (corresponds to a antifreeze protection down to -20 °C)
Complete coolant filling capacity (B):
41 liters
Refill quantity of anticorrosion agent and antifreeze (C): 10.85 liters
