Tools and Materials Needed

  • Oil drain pan
  • Socket wrench set
  • New oil filter
  • Fresh engine oil (check your owner's manual for specifications)
  • Funnel
  • Clean rags

Step-by-Step Guide

1. Prepare Your ATV

Ensure your Polaris Sportsman 90 is on a level surface and the engine is cool. This will prevent burns and ensure all the old oil drains out properly.

2. Locate the Oil Drain Plug

The oil drain plug is located underneath the engine. Use a socket wrench to loosen and remove the plug, allowing the old oil to drain into the oil pan. Be careful as the oil may still be warm.

3. Remove the Old Oil Filter

Using the appropriate tool, remove the old oil filter. Be prepared for some oil to spill out when you remove it. Clean the area around the filter mount with a clean rag.

4. Install the New Oil Filter

Before installing the new oil filter, apply a small amount of fresh oil to the rubber gasket on the top of the filter. This ensures a good seal. Screw the new filter into place by hand until it is snug, then tighten it an additional quarter turn.

5. Add New Oil

Replace the oil drain plug securely. Using a funnel, pour the recommended amount of fresh engine oil into the oil fill port. Check your owner's manual for the correct oil type and capacity.

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, adding more oil if necessary to reach the full mark.

7. Dispose of Old Oil Properly

Take the old oil and filter to a recycling center or an auto shop that disposes of oil properly. Never pour oil down the drain or onto the ground.
