We used just one chain, one at the front where you mentioned and one in the back by where the EGR cooler is iirc. If you look at Henry's pictures, we did it pretty much the same.
Just swap motors they will never know lol
Gonna start this thread as a reference for others who are pulling their motor and come upon a roadblock. Here... Ill start
LMM: Does a fender have to come off to remove the core support?
How do you get the fan off the front of the motor?
We pull the passenger side fender, hood, and radiator support - it makes it much easier to get in and work on everything else and doesn't take long at all.
White Duramax: what kind of torque is your 3/8 impact capable of? Straight through the front is pretty easy.
slide the little lock and then just pull the handle and they come off. They're a little tight
Heres the pics
Dammit, feels like Im pulling so hard they are going to break. If you say so.........
