Tools and Materials Needed

  • Oil filter
  • Engine oil (check your manual for the recommended type and amount)
  • Oil drain pan
  • Socket wrench set
  • Funnel
  • Clean rags

Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is cool. This prevents burns and ensures all the old oil drains out completely.

2. Drain the Old Oil

Locate the oil drain plug under the engine. Place the oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. Once drained, replace and tighten the drain plug securely.

3. Replace the Oil Filter

Find the oil filter, which is typically located near the engine. Use the appropriate tool to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber seal of the filter. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Add New Oil

Remove the oil fill cap and use a funnel to pour the new engine oil into the fill hole. Refer to your owner's manual for the correct oil capacity. After filling, replace the oil fill cap securely.

5. Check the Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a moment for the oil to settle. Use the dipstick to check the oil level, ensuring it is within the recommended range. Add more oil if necessary.
