4.9.2 Topping up of coolant
– Verify if the engine cooling system is in a good condition (no leaks,
clean,...).
– Check the condition of the coolant.
– If the condition of the coolant is outside the limits, the complete
coolant should be replaced (see section “Replacing the coolant”).
– Always top-up with PARCOOL EG.
– Topping up the coolant with water only, changes the concentration
of additives and is therefore not allowed.
4.9.3 Replacing the coolant
Drain
– Completely drain the entire cooling system.
– Used coolant must be disposed or recycled in accordance with laws
and local regulations.
Flush
– Flush twice with clean water. Used coolant must be disposed or
recycled in accordance with laws and local regulations.
– From the Atlas Copco Instruction book, determine the amount of
PARCOOL EG required and pour into the radiator top tank.
– It should be clearly understood that the risk for contamination is
reduced in case of proper cleaning.
– In case a certain content of ‘other’ coolant remains in the system,
the coolant with the lowest properties influences the quality of the
‘mixed’ coolant.
Fill
– To assure proper operation and the release of trapped air, run the
engine until normal engine operation temperature is reached. Turn
off the engine and allow to cool.
– Recheck coolant level and add if necessary.
