it's pretty easy. However because of how vital it is to follow manufacturers specs on torquing the manifold I would sugest getting a manual. Expect to spend between 4 and 6 hours on it. Remove everything from the intake manifold be sure to label everything carefully. Drain the coolant. Remove the intake bolts a1/4 turn at a time until they are all evenly removed. Clean off all traces of gasket material. The joints need to be spotless. It is imperative to not damage the mating surfaces. When you reinstall everything be sure to replace the gaskets in the same direction they came off. Re torque the manifold in three steps 15 foot pounds,then 25, ending at 35 foot pounds. The sequence is essentially middle right, middle left, rear left, rear right, front left, front right. It is more intricate than that which is why i recommend securing a manual.
there is a finite amount of information that will fit in this box, buy the service manual for the vehicle it is a long and complicated proceedure to explain here.
