Change Coolant --- twice a year
NOTE: When genuine Hitachi Long-Life coolant is used,
change every two years or 4000 hours, whichever
comes first.
Clean Radiator Interior
--- when changing coolant
CAUTION: Do not loosen the radiator cap until the
system is cool. Loosen the cap slowly to the stop. Re-
lease all pressure before removing the cap.
IMPORTANT: Use fresh water or normal tap water as a
coolant. Do not use strong acid or alkaline
water. Use the coolant with genuine Hitachi
Long-Life Coolant (LLC) mixed by 30 to 50 %.
1. Remove the radiator cap. Open drain cock (1) on the
radiator to allow the coolant to drain completely.
2. Close drain cock (1). Fill the radiator with tap water and
a radiator cleaner agent. Start the engine and run at a
speed slightly higher than slow idle; when the needle of
the temperature gauge reaches the green zone, run the
engine for about ten more minutes.
3. Stop the engine and open drain cock (1). Flush out the
cooling system with tap water, until draining water is
clear. This helps remove rust and sediment.
4. Close drain cock (1). Fill the radiator with tap water and
LLC at the specified mixing ratio. When adding coolant,
do so slowly to avoid mixing air bubbles in the system.
5. Run the engine to sufficiently bleed the air from the cool-
ing system.
6. After adding coolant, operate the engine for several
minutes. Check the coolant level again, and add coolant
if necessary.
