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 completely.

2. Drain the Old Oil

Locate the oil drain plug underneath the engine. Place the oil drain pan beneath the plug. Use the socket wrench to remove the drain plug and allow the old oil to completely drain into the pan. Once drained, replace the drain plug and tighten it securely.

3. 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. This ensures a good seal. Install the new filter by hand, tightening it securely.

4. Add New Oil

Remove the oil fill cap and insert a funnel. Pour the new engine oil into the engine, checking the level with the dipstick to ensure you do not overfill. Once filled, replace the oil fill cap.

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, turn off the engine and tighten the components as necessary.
