Begin by draining the radiator and coolant reservoir. This write up on alternator bearing replacement has a section describing the best way to do this.

Remove the cross brace and the fan shroud. Then the rest is pretty obvious, except the transmission cooler hoses. These hoses are attached with banjo fittings and copper crush washers. The washers should be replaced with new ones when putting it back together. Have a drain pan ready. Not very much comes out (100 mL), but it is messy. And, the fluid should be refilled when you are done. This is a good opportunity to check fluid level and top it off if you have never done so.
