I am wondering about the plastic fan deflector that sits on top of the fan shroud - it is the one you need to remove to change the serpentine belt. I broke mine when I was changing the serp belt and just recently replaced it, but I was wondering if it is necessary. It looks like it might deflect some fan air on to the alternator, other than that, I am not sure what it does. I had it off for a month without any trouble. I noticed that my friend did not have his - he said it annoyed him years ago so he ditched it ( He also ditched the driver side battery shield/cover).

You hit that right on it does deflect air. A hot alternator does not charge as well
and the diodes really don't like excessive heat. You can get away with it out for
a while if your not charging hard or in high temps.
I did a little test with a non-contact thermometer and I was seeing 150F in under
1 minute at the armature. They heat up FAST.
Speakin of fan shrouds, in process of putting my truck back together to see if it runs. I understand the shroud should be on for numerous reasons but can you start the engine and drive short distance w/o the shroud on?
I don't know how much air they deflect - I was wondering if maybe they are there as a safety feature - they do keep your hands away from the belt. I agree that it was quite nice when it was not there - so easy to change out an alternator or serp belt.
