Tools & Materials Needed

  • Funnel
  • New oil filter

Step-by-Step Guide

1. Prepare Your ATV

Ensure your Scrambler 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 – allow the oil to completely drain into the pan. Once drained, replace the drain plug securely.

3. Replace the Oil Filter

Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber seal of the filter. Install the new filter by hand — do not over-tighten.

4. Add New Oil

Remove the oil fill cap and insert a funnel. Pour the recommended amount of new oil into the engine. Check the oil level with the dipstick to ensure it's at the correct level. Replace the oil fill cap securely.

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 there are no leaks, your oil change is complete.
