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

Place the oil drain pan under the engine. Locate the oil drain plug beneath the engine and use the socket wrench to remove it. Allow the old oil to completely drain into the pan. Once drained, replace and tighten the drain plug 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 proper 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, being careful not to overfill. Check the oil level with the dipstick to ensure it is at the correct level. Replace the oil fill cap once done.

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 signs of leaks. If there are no leaks, your oil change is complete.
