PERIODIC MAINTENANCE AND MINOR REPAIR EAU20070 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. EAU20242 NOTE: The coolant should be between the minimum and maximum level marks. ECA10471 To check the coolant level 1. Place the vehicle on the centerstand and hold it in an upright position. 2. Remove cowling A. (See page 6-8.) NOTE: G The coolant level must be checked on a cold engine since the level varies with engine temperature. G 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.
