Where is the engine oil drain plug located on 4.0 liter in a 1997 Ford Ranger?

On a 1997 Ford Ranger with the 4.0L Cologne V6 engine, the oil drain plug is located on the bottom of the oil pan, towards the front of the engine. It's fairly straightforward to access once you're underneath the truck. You'll likely see it fairly easily as it's a relatively large bolt. However, it's always a good idea to consult a repair manual or diagram specific to your vehicle's year and model for precise location.
