Well, that depends on the ability of you, the tools you have and the luck you have with loosening things that probably don't want to be loosened. It isn't all that bad but I would suggest car ramps to raise the front as often the best and only way is to remove it from the bottom.

I have a 91 Civic with AC. The alternator is relatively easy to change out. First you need to remove the negative lead on the battery and move it so that it will not touch the terminal on the battery. Then jack the car up and put a jackstand under it to support the car(never get under a car that is not properly supported with jackstands!!!!), next you will need to loosen the top bolt above the Alternator(either a 10 or 11 mm), then loosen the bottom bolt(14 mm) you will need to remove the splash shields to gain access to the bottom bolt and to aid in removal, this will allow you to push the alternator towards the engine to remove the belt. After the belt is removed remove the electrical plug on the back of the alternator, then unbolt the battery wire from the back of the alternator. After you have the wiring disconnected you can remove the top bolt from the alternator. Then remove the bottom bolt and pull the alternator out. The installation is just reversing what you have already done. Good Luck.

Suggested Repair
Disconnect the battery negative cable and secure it away from the terminal. Safely raise and support the front of the car with jack stands, remove the splash shields, and loosen the alternator mounting bolts so the belt can be removed. Disconnect the electrical plug and battery wire, remove the bolts, and pull the alternator out from below. Install the replacement by reversing those steps.
Conversation Summary
The owner asked how difficult it is to replace the alternator on a 1991 Honda Civic with air conditioning and a five-speed transmission. One expert said difficulty depends on tools, skill, and seized fasteners, and recommended ramps because removal is often easiest from below. Another owner of a similar Civic described disconnecting the battery, supporting the car, removing splash shields, loosening the bolts, removing the belt and wiring, and pulling the alternator out, then reversing the process for installation.
