Step-by-Step Instructions

1. Prepare Your ATV

Ensure your Grizzly 660 is on a level surface and the engine is cool. This prevents burns and ensures accurate oil drainage.

Locate the oil drain plug under the engine. Place the drain pan beneath it. Use a socket wrench to remove the plug and allow the oil to fully drain. Once drained, replace the drain plug securely.

Use the oil filter wrench to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the filter. Install the new filter by hand, ensuring it's snug but not overtightened.

Remove the oil fill cap and insert a funnel. Pour in the new 10W-40 ATV oil. The Grizzly 660 requires approximately 2.6 quarts. Check the oil level with the dipstick and add more if necessary, but do not overfill.
