  • New oil filter
  • 4 quarts of 10W-40 ATV oil

Step-by-Step Guide

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.

2. Drain the Old Oil

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 into the pan. Once drained, replace the drain plug securely.

3. Replace the Oil Filter

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

4. Add New Oil

Remove the oil fill cap located on the top of the engine. Using 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.

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, tighten the components as needed.

6. Dispose of Old Oil

Properly dispose of the old oil and filter at a recycling center or an auto parts store that accepts used oil.
