How do I replace alternator in mazda mpv 2000?

Typically an alternator is an easy fix. It requires removal of the belt from the engine running it, and a few bolts that attach it to the engine.

Because of the engineering with the 2000 mpv, it is a very difficult fix, and one that requires removal of the transaxle and exhaust manifold, as well as removal of the lower engine mounts. It will take a qualified Mazda mechanic 3.5 hours to do the fix - you can (at least) triple that amount of time as a DIY project (assuming you have the right tools).

It's not difficult to replace the alternator on the 2000 MPV. The sure sign of a problem with the alternator is that your battery is not charging. When my alternator died (not knowing it was the problem), I pulled over to a Walmart, bought a set of $3 wrenches and a replacement battery. When the new battery started to die, I pulled over to an Autozone and purchased an alternator. My car barely made it to my girl friend's house where I replaced it on her driveway. If you are comfortable handling replacing car batteries and using a socket wrench (make sure you have a metric set), then it's not hard. Just do it!

It is not a very difficult task, but one that would be better left to a professional for a couple of reasons. First, the system should be tested to be sure this is going to fix your problem. Many times a bad battery is the demon. Second, you will get a warranty with that repair if you have it done at a reputable garage/dealership. Just a couple of things to think about.
