So how do you know you need one if you dont know where it is?? Oil pumps rarely go bad unless the engine is sludged from lack of maintenence. After you take the oil pan off, its there hanging down. Make sure you clean or replace the pick up tube. I'm sure you can google up torque specs, for the bolts. Usually there is major engine damage by the time you figure out that there is lack of oil pressure. I would get a professionals opinion before you waste time and money replaicing the oil pump. If the engine has any unusual noise or knocking, its too late.
