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

Using a socket wrench, remove the bolts securing the skid plate underneath the ATV. This will give you access to 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 plug and allow the old oil to completely drain out. Be careful as the oil may still be warm.

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 top of the filter. This ensures a proper seal. Install the new filter by hand, tightening it securely.

5. Refill with New Oil

Replace the oil drain plug and tighten it securely. Using a funnel, pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. After filling, check the oil level with the dipstick and add more if necessary.

6. Reattach the Skid Plate

Once the oil is filled, 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 leaks around the oil filter and drain plug. If there are no leaks, your oil change is complete.
