And make sure to take off the fill plug BEFORE you take off the drain plug! If for any reason the fill plug is seized, cross-threaded or otherwise buggered, then YOU will be buggered if you remove the drain plug first
Also think about how you are going to get the new oil into the fill hole. There are at least two possibilities: 1) plastic funnel with 3 foot long flexible tail. Place the funnel between the radiator and inverter, and snake the tail down to the fill hole. 2) hand operated pump that screws on top of the bottle I prefer #1. You will need a 10 mm hex key socket for the drain plug, and a 24 mm socket for the fill plug.
I did mine recently it's just 6" from the empty port, directly toward the front of the car, get good light and look closely, it's recesses a little bit, remember to get the funnel and long (3') rubber tube to use to get the oil to the fill port.
