How to Replace the Alternator in a Honda CR-V
The alternator in a Honda CR-V operates various electrical devices in the vehicle while the engine is running. A voltage regulator keeps the voltage level constant and is usually part of the alternator assembly. You may need to replace the alternator if your headlights become dimmer while driving or your battery repeatedly runs down.

Determine which alternator your Honda CR-V will need. You'll want to be sure the new alternator is compatible with your CR-V's engine. Models made from 1996 to 2001 have a 2.0 L B20B or B20Z engine and models made after 2001 may be equipped with a 2.0 L, 2.2 L turbo diesel or 2.4 L engine.

Yes, mrmekanik. Looking at the Chiltons manual, or even ALLDATA online--which is suppose to be the shop manual--pretty much says the same. I really can't afford the $650 that my local shop charges, because I'm unemployed, but I don't know where to find instructions on how to do it. Any suggestions?

Sorry... Not even close! This is so oversimplified that you might as well have said "Unhook the old one and put the new one in"! There is a WHOLE lot more to this job and, depending on the year of your CRV, (say a 2003) you will also have to remove the radiator and power steering pump to even reach the alternator bolts. It is well worth paying the Honda dealership $400-$500 to have it done.
