Tools and Materials Needed

  • Oil filter
  • 4-stroke engine oil (10W-40 recommended)
  • 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 will prevent burns and ensure 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

Locate the oil filter on the side of 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 new filter. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Add New Oil

Remove the oil fill cap located on the top of the engine. Using a funnel, pour the recommended amount of new 10W-40 oil into the engine. Check the oil level with the dipstick to ensure it is at the correct level. Add more oil if necessary.

5. Check for Leaks

Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any signs of leaks. If there are no leaks, turn off the engine and recheck the oil level, adding more if needed.
