COOLING SYSTEM
Coolant
Proper control of coolant is very important for the Cummins engine, which cannot deliver its
performances fully unless coolant is controlled properly.
Be sure to mix anti-freezing solution, coolant additive and water in the proper ratio, when refilling
the engine with coolant, in order to avoid damages to the engine.

Anti-freezing solution
A new machine is filled with coolant containing 50% ethylene glycol long life coolant (LLC).
This coolant has anti-freezing effect and corrosion resistant effect.
It has long-term effects and may be used in all seasons.
Replace coolant every 2000 hours or 2 years.
Be sure to use long life coolant when replacing coolant.
