Tools & 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 Polaris SPORT 400L is on a level surface and the engine is cool. This will prevent burns and ensure all the old oil drains out completely.

2. Locate the Drain Plug

The oil 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. Once drained, replace the drain plug and tighten it securely.

4. Replace the Oil Filter

Locate the oil filter and use an oil filter wrench to remove it. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. Install the new filter by hand, ensuring it is snug but not overtightened.

5. Add New Oil

Remove the oil fill cap and insert a funnel. Pour the recommended amount of new oil into the engine. Check your owner's manual for the exact oil capacity. Once filled, replace the oil fill cap.

6. Check Oil Level

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