I am trying to upgrade my alternators existing charging and ground wires.

The alternator has a black cooling shroud on the back covering the posts i need to access.

The shroud seems removable, but the rear mounting bar is directly behind the shroud effectively blocking removale of the shroud.

I dont think removing the rear mounting bar (1 of 3 mounting bars) while the alt belt is under tension is a good idea.

So I believe i need release tension on the belt and remove the alternator to gain accsess to the posts.

Or can I just pop the shroud off....?

I think I know what needs to be done, but a step by step guide would be very much appreciated.

Pictures are supplied

Please help

Thanks Very much

Its a 1997 skylark gran sport 3.1 v6

also I figured it out, but if a may ask a different question instead

i was reinstalling the alternator,
the cooling shroud wouldnt fit properly
i realized the shroud has a tab that secures to the underside of the alternator

i was attempting to pop the tab into the correct position with my screwdriver

my screwdriver slipped and I slipped and shorted the alternator charging post against the engine block

sparks flew

i should add that the negative battery terminal was DISCONNECTED the entire time.

I had to leave for work so, I reinstalled the alternator

i checked the voltage at the front battery while the car was running and the voltage read 14.2v which should be normal

is it possible I didnt damage the alternator?
How can I test it?

I have a very high power audio system installed and the voltage meter in the car reads normal 14.5- 14.2v while driving

i played my system at full tilt, and experienced normal voltage drop

is my alt ok did I get lucky, or am I in trouble?

To test the alternator you can start the car let it idle turn your head lights on high beams on turn on your a/c on and see what your voltage is. Let me know what your voltage is sounds like your ok though.

REMOVAL:

Disconnect the negative battery cable.
Label and disengage the electrical connections from the alternator.
On the 2.5L engines, loosen the adjusting bolts and remove the alternator belt.
If equipped with a serpentine belt, loosen the tensioner and turn it counterclockwise to remove the belt.
Unfasten the alternator mounting bolts, then detach the alternator air inlet connector (3.1L engine only) and remove the alternator from the engine.

INSTALLATION:

Fasten the alternator to the mounting bracket, using the retaining bolts, washers and nuts. Tighten the retainers to the specifications listed in the accompanying figures.
