I find it really easy.
Disconnect your battery
Pull the battery cable and connector off the alt.
Remove alt by the three bolts on the front and one on the rear (pic for ref on bottom bolt)
Then after you drain about 1/2-3/4 of a gallon of coolant you are ready to remove the tensioner/alt bracket by pulling the three bolts. One is not visible near the back of the motor. (Pic for ref, your tensioner is nearly the same)
Nothing tricky at all. 5-6 bolts and wiggle it nicely. There is a plastic coolant elbow going into the LIM. There is another metal elbow (part of the tensioner) going into the timing cover. If you pry hard you can crack the timing cover. Wiggling will get it..time and patience will be the winner.
