Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is warm. This helps the oil drain out smoothly. Turn off the engine and let it cool for a few minutes.

2. Drain the Old Oil

Place the drain pan under the engine. Locate the oil drain plug beneath the engine and use a socket wrench to remove it. Allow the old oil to completely drain into the pan. Be cautious as the oil may still be hot.

3. 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.

4. Add New Oil

Reinstall the oil drain plug and tighten it with the socket wrench. Using a funnel, pour the new oil into the engine through the oil fill cap. Refer to your owner's manual for the correct oil capacity. After adding oil, check the oil level with the dipstick and add more 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 leaks. If you notice any, turn off the engine and tighten the components as needed.

6. Dispose of Old Oil

Properly dispose of the old oil and filter at a recycling center or an auto shop that accepts used oil.
