Tools and Supplies Needed

  • Oil filter
  • 4-stroke engine oil (check your manual for the recommended type)
  • 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 and use an oil filter wrench to remove it. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top 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 insert a funnel. Pour the recommended amount of new oil into the engine. Check the oil level with the dipstick to ensure it is at the correct level. Replace the oil fill cap securely.

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, your oil change is complete.
