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 Drain Plug

Place the drain pan under the engine. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. This may take a few minutes.

3. Replace the Oil Filter

Using the oil filter wrench, remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber seal of the new filter. This ensures a proper seal and makes it easier to remove during the next oil change. Install the new filter by hand, ensuring it is snug but not overtightened.

4. Reinstall the Drain Plug

Once the oil has completely drained, reinstall the drain plug. Make sure it is tightened securely to prevent leaks.

5. Add New Oil

Using 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. Add more oil if necessary.

6. 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 you notice any leaks, turn off the engine and tighten the necessary components.
