Chapter 6 COOLANT
Maintenance of LLC
Replacement intervals of LLC
The coolant containing LLC recommended in this manual should be renewed every 8000 hours or 2 years, which-
ever comes first, for a regular-use or general-purpose engine.
LLC concentration
When determining the LLC concentration, provide a margin of 5 °C [41 °F] below the expected lowest temperature
in your region.
LLC of less than 30% concentration does not provide sufficient corrosion protection. If the LLC concentration is
lower than 10%, it may accelerate corrosion.
When adding coolant, do not add plain water. Always use coolant with the same LLC concentration.
Note: (a) When ambient temperature is -30°C [-22°F] or below, use Mitsubishi genuine LLC "GLASSY long life cool-
ant (Ethylene glycol type)".
(b) The concentration above is based on Mitsubishi genuine LLC "GLASSY long life coolant (Ethylene glycol
type)" or "PG GLASSY long life coolant (Non-amine type)".
For determining the accurate LLC concentration, refer to the instructions for the LLC used.
Should coolant or LLC be accidentally swallowed, induce vomiting immediately and seek medical attention. If LLC
should enter eyes, flush immediately with plenty of water and seek medical attention.
LLC is toxic. Never dispose of coolant containing LLC drained from engine into regular sewage. For disposal of
used coolant, consult LLC distributor.
Be sure to renew LLC (coolant) at the intervals specified in the maintenance schedule of this manual.
Failure to renew LLC may cause malfunctions due to deterioration of anti-corrosive performance and cavitation.
