Coolant
Only use Volvo Coolant VCS when topping up or changing coolant. To avoid damage to
engine and cooling system, different coolants or corrosion protection must not be mixed.
When using concentrated Volvo Coolant VCS and clean water, the mixture should contain
40–60% concentrated coolant and 60–40% clean water. The amount of concentrated
coolant must never be less than 40% of the total mixture, see table below.
Freeze protection down to Mixed-in amount of concentrated coolant
-25 °C (-13 °F) 40%
-35 °C (-31 °F) 50%
-46 °C (-51 °F) 60%
The concentrated coolant must not be mixed with water that contains a high degree of
lime (hard water), salt or metals.
The clean water for the cooling system must also meet the following requirements:
Description Value
Total number of solid particles < 340 ppm
Total hardness < 9.5° dH
Chloride < 40 ppm
Sulphate < 100 ppm
pH value 5.5-9
Silica < 20 mg SiO
2
/litre
Iron < 0.10 mg Fe/litre
Manganese < 0.05 mg Mn/litre
Electrical conductivity < 500 µS/cm
Organic material, COD-Mn < 15 mg/litre
If there is any doubt about the water quality, use ready-mixed Volvo Coolant VCS, which
contains 40% concentrated coolant. Do not mix with any other ready-mixed coolants since
this may result in engine damage.
