Tools and Materials Needed

  • Oil filter wrench
  • Socket wrench set
  • Drain pan
  • Funnel
  • New oil filter
  • 4-stroke engine oil (Yamaha recommends 10W-40)
  • Clean rags

Steps to Change the Oil

  1. Warm Up the Engine: Start your ATV and let it run for a few minutes. This helps the oil drain out smoothly by thinning it.
  2. Position the ATV: Ensure the ATV is on a level surface and turn off the engine.
  3. Remove the Drain Plug: Place the drain pan under the engine. Use a socket wrench to remove the drain plug and allow the old oil to completely drain out.
  4. Replace the Oil Filter: Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Install the new filter by hand, ensuring it is snug but not overtightened.
  5. Reinstall the Drain Plug: Once the oil has drained, reinstall the drain plug and tighten it securely.
  6. Add New Oil: Using a funnel, pour the new oil into the engine. The 2004 Yamaha Warrior typically requires about 2.6 quarts of oil. Check the oil level with the dipstick and add more if necessary.
  7. Check for Leaks: Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any leaks. If there are no leaks, turn off the engine.
  8. Dispose of Old Oil: Properly dispose of the old oil and filter at a recycling center or an auto shop that accepts used oil.
