  • New oil filter
  • 4-stroke engine oil (check your manual for specifications)

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. Remove the Skid Plate

Use a socket wrench to remove the bolts securing the skid plate. Set the skid plate aside to access the oil drain plug.

3. Drain the Old Oil

Place the drain pan under the oil drain plug. Use the 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.

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. 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 and add more if necessary. Replace the oil fill cap securely.

6. Reattach the Skid Plate

Reattach the skid plate using the socket wrench to secure the bolts.

7. Check for Leaks

Start the engine and let it run for a few minutes. Check for any oil leaks around the drain plug and oil filter. If there are no leaks, your oil change is complete.
