Step-by-Step Guide

1. Prepare Your ATV

Ensure your ATV is on a level surface and the engine is cool. This prevents burns and ensures accurate oil drainage.

2. Drain the Old Oil

Locate the oil drain plug beneath the engine. Place the oil drain pan underneath and use a socket wrench to remove the plug. Allow the oil to completely drain into the pan.

3. Replace the Oil Filter

Using the appropriate socket, remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. This ensures a proper seal. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Add New Oil

Replace the oil drain plug securely. Using a funnel, pour the new oil into the engine through the oil fill cap. Refer to your manual for the correct oil capacity. After filling, replace the oil fill cap.

5. Check Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a moment for the oil to settle. Use the dipstick to check the oil level, ensuring it is within the recommended range. Add more oil if necessary.
