Pretty straight forward process. Remove the serpentine belt. Remove the leads to the old alternator. There is a bracket on the back of the alternator that attaches to the top of the motor I also removed this but cannot recall if that was necessary. Remove the bolts securing the Alternator and take it out. Reverse the process to put the new alternator back in. The most difficult part is getting the serpentine belt around the bottom pullys as there is very limited access. Thread the belt through the lower pullys first and then work on the idler/tension wheel last to get the belt mounted. I replaced the belt since I had the old one off but it did not look bad even after 110K miles. .

The above answer is a little deceiving. If you have a 12v engine, it's a lot easier than a 24v engine. On the 24v engine, it's buried in the back of the engine on the drivers side and is a pain to remove.

Yes, the 24v DOHC is tough. I thought I was going to have to take out the cv shaft, but I saw an idea was to loosen the motor mounts and carefully lift the engine to get enough clearance to get the alternator out. Put a 2x4 under the length of the oil pan and lift carefully!
