Coat the new oil filter’s O-ring with Polaris 0W40 motor oil. Screw the oil filter onto the oil pump by hand until it is fits snugly against the crankcase. Tighten the oil filter an additional quarter turn, using a strap wrench.
Pour 2 quarts of Polaris 0W40 motor oil into the oil tank. Screw the dipstick into the oil tank.
Start the motor and check the oil drain plugs and the oil filter for leaks. Stop the motor and tighten the drain plugs or the filter if you notice any leaking. Wipe up any spilled oil with a lint-free rag.
Tips & Warnings
Use only API-certified 0W40 motor oil in your Polaris Sportsman 500 ATV.
