The plug for the block heater in a Mazda 3 is typically found near the front of the engine bay, often on the driver's side. It may be located near the oil filter or close to the engine's front. If you're having trouble locating it, consult the owner's manual for specific details related to your model year.
The sump plug on a Mazda 3 is typically located at the bottom of the engine oil pan, which is positioned under the vehicle. To access it, you may need to raise the car and remove any undercarriage covers if present. The plug is usually a hex or square head bolt that requires an appropriate tool for removal. Always ensure the engine is cool and the vehicle is securely supported before attempting to access the sump plug.

The oil plug is on the rear of the Oil Pan. Underneath the car right behind the bumper, almost in the center, you will see the oil filter. The oil pan is right behind this. The plug is on the rear bottom side of the oil pan (about 3' back from the bumper). You'll need a 1/2 " wrench for the plug.
The Mazda 3 will take 4.5 qts or 4.3 liters of engine oil duriing a normal oil and filter change.
