check the LLC concentration every 4000 service
hours for the continuous use engine, and every six
months for the emergency use engine.
"LLC Concentration in Coolant - Measure" (→ Page
114)
Replacement Period
Change the coolant every 8000 hours or 2 years,
whichever comes first for the continuous use
engine. For the emergency use engine, be sure to
change the coolant once every 2 years.
Coolant - Mix
1 Check the LLC concentration in
coolant "LLC Concentration
(Genuine LLC)" (→ Page 113).
2 Check the quantity of coolant to be
refilled.
• When replacing, check the specified
quantity of coolant. "SPECIFICATIONS -
CHECK" (→ Page 10)
• When refiling, check with the scale on the
tank.
• Refill coolant into the engine after
mixing. Do not refill only water or
LLC.
• If coolant is refilled without proper
stirring, partially contrasting density
of the LLC concentration may occur,
which could interfere with the
sufficient anticorrosion and cooling
properties.
3 Prepare a vessel for mixing and pour
in water
"Water to Be Used" (→ Page
111).
4 In accordance with the LLC
concentration checked in Step 1,
add LLC "LLC to Be Used" (→ Page
112).
5 Check the LLC concentration in
mixed coolant. "LLC Concentration
in Coolant - Measure" (→ Page 114)
6 Refill the mixed coolant into the
engine. "Coolant - Change" (→ Page

LLC Concentration (Genuine
LLC)
The concentration of LLC required for anti-freeze is
determined by the ambient minimum temperature.
Be sure to follow the range shown in the following
table.
Do not use LLC after the
recommended storage expiration
date.
* Otherwise, the devices could be damaged.
Keep LLC to be the specified
concentration.
* If LLC concentration is low, it could cause
corrosion of the radiator or heat exchanger.
* If LLC concentration is high, it may cause
damage to the devices or overheat due to the
seized engine parts.
