Not easy at all to get to. If it is the freeze plug then you should figire on taking the whole motor out and replace all of them, becAUSE THEY WILL BE ALL READY TO FAIL AT THIS POINT IN TIME. Easy to replace once the motor is out. Sorry for the caps. There are freeze plugs on the back of the motor too. Those are ones that leaked on my motor and all of mine were paper thin when I replaced them.
