Yamaha XMax YP400RA - Owner's Manual > Final transmission oil

The final transmission case must be checked for oil leakage before each ride. If any leakage is found, have a Yamaha dealer check and repair the scooter. In addition, the final transmission oil must be changed as follows at the intervals specified in the periodic maintenance and lubrication chart.

1. Start the engine, warm up the final transmission oil by riding the scooter for several minutes, and then stop the engine.

2. Place the scooter on the centerstand.

3. Place an oil pan under the final transmission case to collect the used oil.

4. Remove the final transmission oil filler cap and its O-ring from the final transmission case.

9. Check the final transmission case for oil leakage. If oil is leaking, check for the cause.

Coolant

The coolant level should be checked before each ride. In addition, the coolant must be changed at the intervals specified in the periodic maintenance and lubrication chart.

To check the coolant level

1. Place the vehicle on a level surface and hold it in an upright position.

2. Open the front storage compartment A.

TIP

• The coolant level must be checked on a cold engine since the level varies with engine temperature.
• Make sure that the vehicle is positioned straight up when checking the coolant level. A slight tilt to the side can result in a false reading.

3. Check the coolant level through the check window.

TIP

The coolant should be between the minimum and maximum level marks.

1. Maximum level mark
2. Minimum level mark

4. If the coolant is at or below the minimum level mark, remove panel B.

5. Open the reservoir cap, and then add coolant to the maximum level mark. WARNING! Remove only the coolant reservoir cap. Never attempt to remove the radiator cap when the engine is hot.

[EWA15162] NOTICE: If coolant is not available, use distilled water or soft tap water instead. Do not use hard water or salt water since it is harmful to the engine.

If water has been used instead of coolant, replace it with coolant as soon as possible, otherwise the cooling system will not be protected against frost and corrosion. If water has been added to the coolant, have a Yamaha dealer check the antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the coolant will be reduced.

1. Coolant reservoir cap

Coolant reservoir capacity:

0.31 L (0.33 US qt, 0.27 Imp.qt)

6. Close the reservoir cap, and then install the panel.

7. Close the front storage compartment.

Changing the coolant

The coolant must be changed at the intervals specified in the periodic maintenance and lubrication chart. Have a Yamaha dealer change the coolant.

WARNING! Never attempt to remove the radiator cap when the engine is hot.
