Tools and Materials Needed

  • Oil filter
  • 4-stroke engine oil (check your manual for the recommended type)
  • Oil drain pan
  • Socket wrench set
  • Funnel
  • Clean rags

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 all the old oil drains out completely.

2. Locate the Drain Plug

The drain plug is located at the bottom of the engine. Place the oil drain pan underneath it to catch the old oil.

3. Drain the Old Oil

Use a socket wrench to remove the drain plug. Allow the oil to completely drain into the pan. This may take a few minutes.

4. Replace the Oil Filter

While the oil is draining, locate the oil filter. Use the appropriate tool to remove the old filter. Before installing the new filter, apply a little oil to the rubber seal to ensure a good fit. Install the new filter by hand, ensuring it is snug but not overly tight.

5. Reinstall the Drain Plug

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

6. Add New Oil

Using a funnel, pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. After adding the oil, check the level with the dipstick and add more if necessary.

7. 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, tighten the components as needed.
