First off warm the engine up to operating temp. If my memory serves me correctly, You will need a 14mm whrench for the drain plug, A receptical for the old oil, A new oil filter (I use toyota brand ) and 5.7 qts. of oil (I use mobil 1 5w-30 full synthetic ) The drain plug is right behind the under cover in the center of the car (Not the one further towards the rear of the car, That is the tranny plug. Wrench out the drain plug with the oil receptical under the drain plug and drain until the drips stop. Remove the oil filter and replace with new one, Put the drain plug back in ( with new crush washer if desired ) good and tight, Not too tight, Then add new oil. Just do not overfill.
