3.12 CHECKING THE ANTIFREEZE CONTENT IN THE COOLING SYSTEM
When the coolant is hot, there is an
overpressure in the cooling system.
Carefully remove the filler cap to
release the overpressure.
Coolant is a toxic fluid. Contact with
the skin should therefore be
avoided.
In order to avoid damaging the
cylinder block, do not top up a
warm engine with cold coolant.
1. Check the antifreeze content of the coolant.
Fill the cooling system with antifreeze, if this
has not been done yet. Always use only
those c oolants or antifreeze agents which
meet DAF specifications.
2. Consult the manufacturer’s instructions for
the c orrect antifreeze mixing ratio.
Preferably, use 40% antifreeze, on an
ethylene glycol base. At this percentage,
not only good frost protection, but also good
corrosion protection is guaranteed.
