Where is the drain plug on a 1998 sonoma?

The drain plug on a 1998 GMC Sonoma is located on the oil pan, which is situated underneath the engine. To access it, you'll need to lift the vehicle safely and look for a large bolt or plug at the lowest point of the oil pan. It's typically a hex or square shape, allowing you to use a socket or wrench to remove it for oil changes. Always ensure to have a drain pan ready to catch the old oil when you remove the plug.
