(Except FL22 type engine coolant)

7. Refill the engine coolant into the coolant reserve tank up to the F mark on the tank.

8. Install the cooling system cap.

CAUTION:

-

If the water temperature gauge rises too high, stop the engine and decrease the engine coolant temperature to prevent overheating. Then, verify
the malfunctioning part and repair or replace it.

-

If the engine coolant level in the coolant reserve tank is below the L mark during engine coolant air bleeding operation, stop the engine, and
after the engine coolant temperature decreases, add engine coolant. Then, resume the engine coolant air bleeding operation.

9. Start the engine and warm up the engine by idling.

10. After the engine warms up, perform the following steps. At this time, be careful of the engine coolant temperature to prevent overheating.

NOTE:

1

If the accelerator pedal is depressed continuously for a specified time, the engine speed may decrease to the idle speed. This is does not
indicate a malfunction.

a. Run the engine at approx. 4,000 rpm for 1 min.

b. Run the engine at idle for 1 min.

c. Repeat step (1), (2) several times.

11. Stop the engine, and inspect the engine coolant level after the engine coolant temperature decreases. If it is low, repeat steps 7-10.

12. Inspect for engine coolant leakage.  See: Testing and Inspection/Engine Coolant Leakage Inspection
