8-2. Checking Coolant
CAUTION : BURNS
Do not open the radiator cap immediately after stopping the engine. Do so
will result in steam gushing out.
Hot steam gushes out from the coolant sub-tank if the generator overheats.
Do not touch the coolant subtank.
Check that the subtank coolant level is in between FULL and LOW. If the subtank coolant is
lower than the LOW level, add coolant to the subtank and radiator.
(1) Filling the Sub-Tank
Remove the sub-tank cap.
Fill the sub-tank with coolant until it reaches
the FULL line.
Re-attach the cap.
(2) Filling the Radiator
Remove the radiator plate.
Remove the radiator cap.
Fill with coolant through the filler neck until
the radiator is full.
Re-attach and tighten the radiator cap.
Attach the radiator plate.
< Note >
Be sure to use the long life coolant (LLC) for the aluminium radiator only. The coolant
should be mixed good quality softened tap water with anti-freezing and anti-rust liquid.
At ex-factory, the LLC mix ratio is 30% liquid and 70% water is installed.
(Isuzu Genuine LLC: Besco LLC Super-Type E)
Be sure to use the same LLC into sub tank.
The mix ration should be changed to ambient temperature but between 30 and 50%.
When replenishing LLC, be sure to use the same brand as the LLC left in the radiator
and sub tank.
Never use the mixed LLC by different brands.
Be sure to change wholly in less than 2 years or 1000 hours.
