If anyone has ever changed the small (3/8", 1/2" maybe) freeze plug on the passenger side of the back of the head (the head is sort of chamfered on the back, passenger side corner, and the plug is in that surface facing about 45 deg. from the truck's center line), I'd appreciate your sharing your experience. I'm mostly concerned with how to get the old one (leaking, on my truck) out, given it's brutal location (Cummins Northeast wants 4 hours to change it).
