8-2. Checking Coolant
CAUTION : BURNS
Do not open the radiator cap immediately after stopping the engine. Doing 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 Sub-Tank.
Check that the Sub-Tank coolant level is in between FULL and LOW. If the Sub-Tank coolant is
lower than the LOW level, add coolant to the Sub-Tank and radiator.
(1) Filling the Sub-Tank
Remove the sub-tank cap.
Fill the sub-tank with coolant until it reaches
the FULL line.
Install the sub tank cap.
(2) Filling the Radiator
Open the top plate.
Remove the radiator cap.
Fill with coolant through the filler neck until the
radiator is full.
Install and tighten the radiator cap.
Close the top plate.
< Note >
Use GM SPEC 6277M or equivalent.
Use a 50:50 mix of Long Life Coolant (LLC).
Always use potable water when mixing the coolant.
Use LLC with the same mixture ratio in the coolant sub-tank.
Do not increase the LLC mixture ratio unless it is necessary. Doing so could result in overheating
or another fault/malfunction.
If adding LLC, be sure to use the same brand/type that is still in the generator.
Do not mix different brands/types. Doing so could result in a chemical reaction and the creation of
toxic substances.
Change the LLC every 2 years or 1,000 hours.
LLC is a toxic substance. Wear rubber gloves and other protective wear when handling.
If someone mistakenly ingests LLC, induce vomiting immediately and seek medical care.
If LLC gets on skin or clothing, wash with water immediately.
LLC is flammable. Store in a location where flame is prohibited and it cannot be accessed by
children.
