Can I replace alternator myself?

loretts

Any motor heads out there that would comment on replacing the alternator by oneself? Any one with the experience of having done this? I have a 1996 Subaru Impreza and the alternator is definitely going. All the warning signs, - flickering dash lights and headlights. I am mechanically handy and have done other things myself. Have new battery and new starter, just hard right now to squeeze out the $$ for another major repair cost.

Sure, it's pretty easy. Here are two videos and between the two it should cover any variations you might come up against. Be SURE to disconnect the battery. If your radio requires a code, be sure you have it before you disconnect the battery. You can also buy a simple battery "substitute" device that plugs into your cigarette lighter.

Diagnosing Alternator Problems

The video pretty much guide you through it step by step, and the Video #2 gives you ways to diagnose the alternator, so that you don't replace it unnecessarily.

Not knowing you expertise and tools at hand, this is impossible to answer. You say you're mechanically handy but have to ask? I would have no problem though.

Dude, yes, that IS right, I am asking for comments on anyone's experience in doing this job. Easy; wish they hadn't taken it on; first time; have done it one thousand times; etc.
I listed my car in case someone out there has the same, has done this job and can make an intelligent comment to guide a first timer. I have looked at video's and will look at Mr. Shiftright's video's.

Hello. I have watched the video's and have tested using the volt meter. With the car running and a load on, it fluctuates between 12.6 and 13.26. When I shut lights, etc. off, engine still running, meter reading drops to 14.00 - 13.99. With engine off and after sitting for a few minutes, meter reads 12.55. I also went to AutoZone, where they tested for free, first test came up battery no good. It is a month old. Tested again, battery showed good, then showed alternator bad, regulator bad. I didn't get a print out.

Well before you go replacing the alternator, be sure all your battery cables and alternator connections are clean and tight.
