Operation & Maintenance Manual
Operation in Winter
Preventing Coolant from Freezing
When only water used as coolant without mixing with antifreeze, corrosion in the engine,
degradation of cooling efficiency, and freezing of the engine in winter may occur. If the
engine is not operated for a long period during cold weather or in areas with cold climate,
fully discharge the coolant from the engine. Freezing of coolant leads to critical damage to
the engine. Please use a mixture of coolant with antifreeze at recommended ratio when
replacing or replenishing the coolant. The antifreeze prevents coolant from freezing.
Preventing Overcooling of the Engine
When the engine is cooled below the normal operating temperature, thermal efficiency
is lowered and fuel consumption as well as abrasion of the cylinder liner may increase.
Therefore, the engine should be operated within the normal operating temperature. If the
engine has been sufficiently operated, but the temperature of coolant remains below the
normal operating temperature, check the water temperature controller or other parts related
to the cooler.
Engine Oil
When viscosity of engine oil increases due to its low temperature during cold weather or in
areas with cold climate, the rpm may not be stable after starting the engine. To prevent this,
replace oil to engine oil for cold weather or areas with cold climate. When replacing engine
oil, use only genuine engine oil recommended by Doosan.
