Tools & Materials Needed

  • Oil filter
  • 4 quarts of 10W-40 ATV oil
  • Oil drain pan
  • Socket wrench set
  • Funnel
  • Clean rags

Step-by-Step Instructions

1. Prepare Your ATV

Ensure your Raptor 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 oil drain pan beneath it. Use a socket wrench to remove the drain plug and allow the old oil to completely drain out. Once drained, replace the drain plug securely.

3. Replace the Oil Filter

Locate the oil filter on the side of the engine. Use the appropriate tool to remove the old oil filter. Before installing the new filter, apply a small amount of new oil to the rubber gasket on the top of the filter. Install the new filter by hand, ensuring it is snug but not overtightened.

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 Raptor 660 typically requires about 2.5 quarts, but check your owner's manual for the exact capacity. Replace the oil fill cap once done.

5. Check Oil Level

Start the engine and let it run for a few minutes. Turn it off and wait a few minutes for the oil to settle. Use the dipstick to check the oil level, ensuring it is within the recommended range. Add more oil if necessary.
