manufacturer's operation manual.
1.
Make sure coolant drain cocks are closed securely.
2.
Remove the radiator cap, and add a mixture of wa-
ter and LLC of the specified concentration to the
specified level.
Note: (a) Determine the quantities of LLC based on the
coolant capacity and the LLC concentration
chart.
For the coolant, refer to
"COOLANT" (6-1)
.
For the coolant capacity, refer to
"MAIN
SPECIFICATIONS" (12-1)
.
(b) For absolute air bleeding, loosen the air vent
plug.
3.
Check the radiator and other parts for coolant
leaks. Repair leakage if found.
4.
When coolant reaches the specified level, close the
radiator cap securely.
5.
With the manual stop lever placed in the pulled po-
sition, crank the engine for approx 10 seconds us-
ing the starter. Stop cranking for 1 minute, then,
repeat the cranking two or three times to bleed the
cooling system.
