Had to replace Henry's alternator today.
Yesterday, it was below 30ºF and starting up was pretty difficult for Henry. Right as I got to work, the Charge System light illuminated on the dash. Once I got home, I checked the voltage of the battery = 12.08v. Engine on, all accessories off = 11.80v. Strong indicator that it's alternator.
I wanted OEM, but settled for new "Nippon-style" from NAPA, because it was in stock nearby. Part Number NRO 1N9549.
Now, I am someone who doesn't know much about diagnosing and troubleshooting, or mechanics in general, and I don't just know off the top of my head what an alternator replacement job looks like. I'm always watching videos and searching and asking public forums. All that said, I feel like this was an upfront - albeit frustrating at times - job that I think most people could do.
The absolute hardest part is getting the drive belt back onto the power steering pump. I searched high and low, online and offline, for a long 14mm wrench, and Harbor Freight had the longest one (and only one) and it was not long enough. Really wish I'd gotten the serpentine belt tool. Ultimately, I put all of my weight on the wrench (I'm only 142 pounds...), and my palm still hurts like hell even while wearing gloves.
I removed the splash guards on the driver side. I don't think this is necessary. It definitely makes it a bit easier, but if you can reach down from above, you don't need to do this. I now can't get the splash guard lined up with the holes to secure it fully. What's more is that the bottom splash guard also has to come out, and I was only able to get 3 of the 8 clips back in, so it's pretty floppy right now.
The alternator was replaced by a shop when the previous owner had it. That was at 124,000 miles. We're now at 188,950. Let's hope this one lasts longer than that!
So shiny! I went ahead and replaced the belt. Old one didn't show any signs of trouble, but for $40, why not? Plus, the one that was on there was not Bando, so it would have gone sooner than I'd prefer.
Here's the routing from the service manual.
These clips are the hardest things to find! Does anyone know where to get new ones that actually fit? I've purchased some on three separate occasions and neither have fit.
