Cooling system
Coolant
The coolant contents (%) must be checked every
2000 hours and the coolant needs to be changed
every 6000 hours. This work must be done by a
service technician.
NOTICE
If the warning of high coolant temperature is shown
on the display unit, the engine must be stopped
immediately.
The cooling system is filled with Volvo Coolant
VCS, which fulfils the highest requirements
regarding freeze-, corrosion-, and cavitation
protection. To avoid damage to the engine, it is very
important that Volvo Coolant VCS is used when
filling or changing the coolant.
Volvo Coolant VCS is yellow and a decal by the
filling point shows that the system is filled with this
coolant (see picture).
NOTICE
Volvo Coolant VCS must never be mixed with any
other coolant or corrosion protection to avoid
damage to the engine.
The cooling system capacity when changing, see
page
186
.
If concentrated Volvo Coolant VCS and clean water
(see page
182
) is used, the table below shows the
approximate amount of concentrated coolant
needed for freezing protection. The content of Volvo
Coolant VCS must never be less than 40% of the
total mixture.
If in doubt of the water's quality, use the ready-
mixed Volvo Coolant VCS, which contains 40%
concentrated coolant.
