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.

FULL line.
Re-attach the cap.

< Note >
Be sure to only use long life coolant (LLC) for the
aluminum radiator. The coolant should be mixed with
good quality softened tap water, and contain
anti-freezing and anti-rust components.
The LLC mix ratio is 30% liquid and 70% water when shipped from the factory. (Isuzu
Genuine LLC: Besco LLC Super-Type E)
Be sure to use the same LLC in the sub-tank.
The mix ratio should be changed according to the ambient temperature but should
remain between 30 and 50%.
Do not increase the LLC mixture ratio unless necessary. Doing so could result in overheating
or another fault/malfunction.
