Tools & Materials Needed

  • Oil filter wrench
  • Socket set
  • Drain pan
  • New oil filter
  • 4-stroke engine oil (check your manual for specifications)
  • Funnel
  • Rags or paper towels

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 under the engine. Place the drain pan beneath it. Use a socket wrench to remove the plug – be careful as the oil may still be warm. Allow all the oil to drain completely.

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. This ensures a proper seal and makes future removal easier. Install the new filter by hand — do not over-tighten.

4. Add New Oil

Reinstall the drain plug securely. Using a funnel, pour the new oil into the engine. Refer to your owner's manual for the correct oil capacity. After adding oil, check the level with the dipstick and adjust 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, tighten the components as needed.
