first big tip, take the 4 small bolts off the w/p pulley before you take the belt off, next, you need to have a t 55 bit (one of them star tips) to remove the lower idler, and the power steering pump to get the 4 long bolts off.

clean the water pump housing up real good, nice and smooth, no left over gasket. the 4 long bolts need thread sealant put on the threads as they go into the water jacket of the block, coolant will come out when you remove the bolts.

take the fuse box and use some string to move and hold it up out of the way to add a few more inches of room, you looking at the bottom of mine in this pic. if you have the coolant bottle right there remove it too.

use no rtv, put the new gasket in dry.

heres what it looks like off.
