How can I locate sump plug of my car?

Buy a Haynes manual for the car, it will always be useful.

this will explain how to get the shield out of the way.

Its usually assessed by removing the right front wheel (WHEN viewed sitting in the car) there will be screws and clips to remove the plastic and then you will observe the drain nut.

Always replace the copper washer with a new one and tighten to the correct torque, buy this washer before you begin the job from a motor factors.

Start the car and allow to run until warm (the old oil will flow out better than cold. Working from underneath, the plastic covers should be secured by 4-6 Phillips/crosshead screws (might be hidden by oil/dirt) once these are removed the plastic can be easily removed, you will then see the bottom of the oil sump. Right at the very bottom of the sump you`ll see the sump plug - a 17mm hex-head bolt. It will be quite tight so be careful when you unscrew, make sure you have a large container directly underneath to catch the old oil!!! Oh, and try not to lose the brass washer on the bolt!!! Good luck.

Your handbook in the glove compartment will show you the access hole or how to remove the pain in the butt shield under the motor.

Yes you do, but sometimes there is a little windoe [flap] you can open to locate the sump bung.

Get the Haynes manual.

it should tell you in the owners manual but there is the trusty haynes manual to fall back on :p
