Coolant
Coolant with antifreeze and corrosion protection
Anti-freeze
Check the antifreeze properties every 500 hours.
When delivered from the factory, the cooling system is filled with a
mixture of water and concentrated Volvo Construction Equipment
antifreeze, which lowers the freezing point and raises the boiling
point of the coolant.
Corrosion protection
Volvo Construction Equipment concentrated antifreeze contains
active anti-corrosion additives in order to protect the engine and
radiator. These additives have a limited durability.
Therefore, change the coolant every 3000 hours or every two
years if a coolant filter is installed.
NOTE :
The Volvo Construction Equipment concentrated anti-freeze
must not be mixed with any antifreeze or additives of another
make. The mixing may have a negative effect.
The antifreeze content must not be less than 40%.
The cooling system capacity when changing is approx. 65.4 liters
(17.2 US gal).
40% lowers the freezing point to -25 °C (-13 °F).
50% lowers the freezing point to -37 °C (-35 °F).

Checking coolant level

Check the coolant level daily.
WARNING!
Immediately after operating the engine, the coolant is very
hot. Do not open the radiator cap until it has cooled down,
then open the cap slowly to release the internal pressure.
1 Open the engine hood.
2 Check the coolant level (B).
If the level is in the center of gauge (B), the level is normal.
3 If the coolant is invisible in the sight gauge, refill through (A) up
to B level.
