I don't know wich engine you have so here is the procedure for the most common engine in this vehicle. The procedure will be very simmilar for all the gas engines. The diesel motor will be a little different so I will include that procedure also. You will need a power steering pump pulley remover and installer to perform this operation, and of course a good set of basic hand tools.
