Step-by-Step Instructions

1. Prepare Your ATV

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

Locate the oil drain plug beneath the engine. Place the drain pan underneath and use a socket wrench to remove the plug. Allow the old oil to completely drain into the pan.
