Draining Coolant

CAUTION

• Do not remove the radiator cap while operating or

immediately after stopping. Otherwise, hot water will spout
out from the radiator. Wait for more then 10 minutes to cool
the radiator, before opening the cap.

1. Place a vessel underneath the water drain plug (1).

2. Open the water drain plug (1), and remove the radiator cap to

completely drain the coolant.

3. After all coolant is drained, close the water drain plug (1). 

Refer to

Draining Engine Oil

CAUTION

• Be sure to stop the engine before draining the engine oil.

1. After warming up, stop the engine.

2. Place an oil pan underneath the oil drain plug (1).

3. Open  the  oil  drain  plug  (1),  and  remove  the  oil  filler  cap  to

completely drain the engine oil.

4. After all engine oil is drained, close the oil drain plug (1).
