Correcting anticorrosion/antifreeze concentration

Warning

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

Warning

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. 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 containers.
Wear protective gloves, protective clothing and safety glasses.

Correcting anticorrosion/antifreeze concentration

Example calculation

N20.00-0376-04

Example of calculation:
Measured antifreeze protection -20 °C = 32 % by volume anticorrosion and antifreeze protection concentration (A)
Total coolant filling capacity (B) = 41 l
Required top-up quantity of anticorrosion and antifreeze protection (C) = 10.85 l

1

Enter anticorrosion and antifreeze protection concentration (A) into formula.

2

Enter total coolant capacity (B) into formula   .

3

Calculate required top-up quantity for anticorrosion and antifreeze protection (C).

4

Drain coolant in the calculated top-up quantity of anticorrosion and antifreeze protection (C) at the cooler drain hose.

5

Add the calculated top-up quantity of anti-corrosion and antifreeze agent (C) into the cooling system.

6

Start engine and run at varying engine speeds for approx. 1 min.
