wow,entertaining thread.
There actually is some good info here amongst the pissing match,LOL
I would have never thought there was a difference from B13-B14 as far as removing the alt.
I know I have replaced my alt in an NX w/a/c on the side of the road before without removing the water neck.I have done it a couple times,actually.
You have to rotate it exactly to the right angle and position.Its like it only goes through one way.It must be the a/c lines being different that changed that as Will stated.
One time I was wrestling it and about to give up...and then it came out.
...just another reason B13 is better than B14...LOL J/K
