Change Coolant
--- every two years or 2000 hours
NOTE: In case genuine Hitachi Long-Life Coolant is
used, change the coolant every two years (in
autumn every other year), or every 2000 hours,
whichever comes first.
WARNING: Do not loosen the radiator cap unless
the system is cool. Hot steam may escape,
possibly causing severe burns. Loosen the
radiator cap slowly to the stop after the coolant
becomes cool. Release all pressure before
removing the cap.
Procedure of Coolant Change
1. Remove the radiator cap. Open drain cock (1) on the
radiator and drain the drain valve on the water jacket
to allow the coolant to drain completely. Drain
impurities such as water scale at the same time.
2. Close radiator drain cock (1) and the drain valve on
the water jacket. Fill the radiator with fresh water
including less impurity and a radiator cleaner agent.
Start the engine and run it at a speed slightly higher
than slow idle to raise the coolant temperature until
the needle of the temperature gauge reaches the
white zone. Then, run the engine further for about ten
minutes.
3. Stop the engine and open radiator drain cock (1) to
allow the coolant to drain. Flush out the cooling
system with fresh water including less impurity, until
draining water becomes clear. This helps remove
water scale.
4. Close radiator drain cock (1). Fill the radiator with
fresh water which includes fewer impurities and LLC
at the specified mixing ratio. When adding coolant, do
so slowly to avoid mixing air bubbles in the system.
Run the engine to sufficiently bleed the air from the
cooling system.
5. After adding coolant, operate the engine for several
minutes. Check the coolant level again, and add
coolant if necessary.
