Where is the oil drain plug located on 2007 ford ranger 4 cylinder?

The oil drain plug on a 2007 Ford Ranger 4-cylinder engine is located on the bottom of the oil pan. To be more specific, it's on the driver's side (left side) of the oil pan, near the front of the engine.

You'll need to get underneath the vehicle to access it. It's usually a 13mm or 15mm bolt (check your owner's manual to be sure). Be careful when removing it, as the oil will be hot if the engine has been recently run. Have a drain pan ready to catch the oil.
