Step 1: Prepare Your ATV
Ensure your ATV is on a level surface and the engine is cool. This will prevent burns and ensure all the old oil drains out completely.
Step 2: Drain the Old Oil
Locate the oil drain plug underneath the engine. Place the oil catch pan beneath it. Use a wrench to remove the drain plug and allow the old oil to completely drain out. Be patient as this may take a few minutes.
Step 3: Replace the Oil Filter
While the oil is draining, locate the oil filter. Use an oil filter wrench to remove the old filter. Before installing the new filter, apply a small amount of new oil to the rubber seal of the new filter. This ensures a proper seal and makes future removal easier. Install the new filter by hand, ensuring it is snug but not overtightened.
Step 4: Add New Oil
Once the old oil has drained, replace the drain plug securely. Use a funnel to add the new oil into the engine. Refer to your owner's manual for the correct oil type and capacity. After adding the oil, check the oil level with the dipstick to ensure it is at the correct level.
Step 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 you notice any leaks, turn off the engine and tighten the components as necessary.
Step 6: Dispose of Old Oil Properly
Take the old oil to a recycling center or a place that disposes of oil properly. Never pour it down the drain or onto the ground.
