How do I remove the air conditioner bracket so I can get to the alternator?

its nuts and bolts.
what is the question on those?
generic:
1: remove battery neg lug first or , BOOM battery acid in face.
2: relax belt tension (all this is in the FSM or alldata.com _)
3: remove all bolts on the alternator pivots. 3 or 4.
5: remove all wires.
6: it now falls off

1. Disconnect the negative battery cable.
2. Remove the battery.
3. Remove the drive belt.
4. Remove any splash shielding for easier access to the alternator.

1. Tag and disengage the alternator wiring.
2. Unfasten the alternator upper and lower bolts.

The alternator can be removed from above by taking it off its mountings, moving it rearward and lifting it out, being careful to gently move aside the refrigerant hoses, if equipped with A/C.
New alternators should come with a new bushing. If not, the old bushing should be used. Push out the pivot bushing as illustrated.

1. Mount the alternator to the brackets with the nuts and bolts. Tighten the two mounting bolts and nuts to 40 ft. lbs. (54 Nm).
2. If the alternator and mounting bracket were removed as an assembly, install the assembly into the vehicle.
3. Engage the alternator electrical connections.
4. If removed, install the splash shield.
5. Install the drive belt and attach the negative battery cable.

The voltage regulator is built into the Alternator.

FOR THE 2.2L AND 2.5L ENGINES TO REMOVE WATER PUMP THE AIR CONDITIONER COMPRESSOR AND BRACKET NEED REMOVING AND ALTERNATOR AND BRACKET HAS TO BE REMOVED BEFORE WATER PUMP CAN BE REMOVED.

Simply follow the steps

Disconnect the battery's negative cable and set it aside where it can't accidentally snap back onto the terminal.

Remove the car's accessory drive belt. Disconnect the belt shield by removing its two 10-mm bolts, push up on the tensioner by hand, pull the belt off the air conditioner or water pump pulley and remove the rest of the belt. Take note of how the belt loops around each pulley.

Open the cover containing the alternator's electrical connectors and disconnect them. Remove the bolt on the coolant expansion tank then detach the tank from its clip and secure it away. Detach the power steering reservoir, engine wiring loom bracket, ground cable and evaporative emission canister purge valve.

Unscrew and remove the alternator's first bolt on its right side. Unscrew the second bolt on the left and disengage it fully from the bracket; it cannot be removed from the alternator. Remove the alternator from the engine.

Install the new alternator, placing the built-in bolt within the bracket and tightening it first. Insert and tighten the second bolt.

Replace all other objects set aside in the reverse order they were detached. (evaporative emission canister purge valve, ground cable, engine wiring loom bracket, power steering reservoir and coolant expansion tank). Plug in the electrical connectors and replace the cover over them.

Replace the accessory drive belt. Loop it over all the pulleys except the one on the air conditioner. Retract the tensioner upwards as you did before to fit the belt on the A/C pulley.

Reconnect the battery cable.

I believe the air conditioner belt tensioner bolt is underneath the mounting bracket on the compressor, then you can remove the alternator belt by loosening the two bolts from underneath on the alternator then loosen the top bolt and be careful prying the alternator inward to loosen the belt you can short a wire connection. Remove one of the battery cables to be safe!

First you must remove the alternator belt. Loosen the alternator bracket then the alternator tensioner bolt, and remove the alternator belt. Then you have access for the a/c belt.

First, you will need a lot of money. A GM air conditioner compressor is very expensive.

I would only let a qualified mechanic make this replacement.

After all, the compressor costs about 800 to 1,000 dollars. i would only trust a mechanic to work on my cadillac
