Make sure the Engine is on a level surface. b. Remove dipstick. c. With a dry cloth, wipe the oil off of the stick. d.
Changing the oil Worn out or dirty oil does not cool the Engine properly and can lead to catastrophic engine damage. In addition to regular oil changes, it is necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. 1. Remove drain plug Using a 10 mm hex wrench, unscrew the oil drain plug, which is located on the crankcase underneath the oil filler/dipstick cap. Allow all the oil to drain from the Engine. 2.
