Strat is right, a service manual and a torque wrench are necessities if you are doing your own work. Maybe you are working on this already but we're trying to help you avoid other's pitfalls just in case. the oil plug is steel and going into aluminum so the torque value is pretty low. Not sure on yours, it might be a different sized plug but on the 1500, the ft. lbs is about 27 if I remember right. Point being, that is a $3000 mistake if you strip out the treads. Sometimes, that being mentioned in the service manual is a good reminder even if you are a veteran mechanic.
And $100 for a book and wrench is recovered the first time you use them.
