you have to remove plastics, then remove your exhaust system. remove all the bolts holding the oil pan, i think they are 14 bolts. remove the pan, remove the gasket. do not use razer blade or scraper to remove the old gasket from the block side, use a hand wire brush. make sure you your regulator don't fall from the block. install your gasket on the alignment pins, install your oil pan & torque the bolts to 10 N-M or 7 LB-Ft. the last one is inch pound, not foot pound.
one more advice, don't thight all four corners first.
good luck
