Coolant Level - Check
Never open the coolant expansion tank cap during
the operation or immediately after stopping. Stop the
engine and after coolant has sufficiently cooled
down, open the cap.
When opening the coolant expansion tank cap, raise
the lever to the upright position to release internal
pressure.
The coolant is hot while the engine is running and
immediately after the engine stops. Do not open the
cap when the coolant is hot to prevent accidental
burns due to hot steam and boiling water. To prevent
burn injuries from hot steam, wear thick rubber
gloves or wrap a cloth around the cap.
When fastening the coolant expansion tank cap, be
sure to tighten securely.
When adding coolant, use the same LLC concentra-
tion coolant that is currently in the cooling system.
1. Check the coolant level in the coolant expansion
tank with the level gauge.
2. If the coolant level is low, add coolant to the speci-
fied level.
Note: (a) Determine the quantity of LLC based on the
coolant capacity and the LLC concentration
chart.
(b) For coolant, refer to
"COOLANT"
(6-1).
