I've done this a few times.... let me give you a few quick pointers. You
don't need to drain the coolant! (although i did the first time!)...

First remove the oil filter
remove the big nut
use a big easy-out (broken stud remove tool. It grabs the pipe fro teh
inside) to remove the pipe
replace the o-ring (green o-ring (Viton), not black (n-butyl))
put pipe back in. Use NO thread sealant!! else you risk cracking the
block....
put nut back on .
new filter on
oil in engine.
drive.
