Engine Oil Replacement

WARNING:
  • Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled.
  • A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands.
  • Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.
CAUTION:
  • If engine oil is spilled on the exhaust system, wipe it off completely. If you fail to wipe the spilled engine oil, it will produce fumes because of the heat.
  1. Position the vehicle on level ground.
  2. Remove the oil filler cap.
  3. Remove the service hole cover (installed to front under cover No. 2) used to drain the engine oil.
