Tools and Materials Needed

  • Oil drain pan
  • Socket wrench set
  • New oil filter
  • Fresh oil (check your owner's manual for the recommended type)
  • 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. Drain the Old Oil

Locate the oil drain plug underneath the engine. Place the oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. Be patient as this may take a few minutes.

3. Replace the Oil Filter

While the oil is draining, locate the oil filter. Remove the old filter using an appropriate tool. Before installing the new filter, apply a small amount of fresh oil to the rubber gasket on the top of the filter. This ensures a proper seal. Install the new filter by hand, ensuring it is snug but not overly tight.

4. Reinstall the Drain Plug

Once the oil has completely drained, reinstall the drain plug. Tighten it securely with the socket wrench, but be careful not to overtighten as this can strip the threads.

5. Add New Oil

Using a funnel, pour the recommended amount of fresh oil into the oil fill cap located on the top of the engine. Check your owner's manual for the exact oil capacity. After adding the oil, replace the oil fill cap securely.

6. Check Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a couple of minutes 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.
