So this morning I was greeted with the battery light.  Pretty sure it is the alternator.  I haven't had to deal with alternators for a long time so I know nothing about brands or anything really.  Are there any brands that are going to be better than others?  AC Delco, Bosch?

 

Thanks guys!

 

PHBT engage!

Unhook it from the battery posts while it's running to see if indeed it's the alternator. You can also use a voltmeter across the battery poles. Depending on use and how old the truck is I usually would pull one from a scrap yard

are you buying new or reman'd??  new the brand isn't going to matter much, delco, bosch, etc are all going to serve just fine.  make sure you are checking your battery as well, they often go hand in hand, in fact I've had a bad alternator take out a perfectly good battery.  worth checking anyway

Definitely going new.  Being I got about 120k miles on the original I'm leaning towards just getting the OEM one and calling it a day. 

 

I've suspected the bearing in the alternator was going out for a while as I'm getting a rattle type noise on cold startup.  Looks to be a pretty easy job from what I'm seeing on youtube.

the oem is probably made by bosch or delco anyway, no reason to pay stealership prices just to have oem

yup, but check the stamping on the housing, it might be made by bosch or delco.  I currently have a delco on my truck, has served faithfully for about 4-5 yrs now

Got the Delco. Went to put it in yesterday evening and the damn pulley was bent. No way am I putting that in the truck and feck up my belt.

Had to go back this morning and they had to pull my old pulley off and put it on the new alternator. Got it put in in about 20 mins. Easy job. No more battery light and I can swear the truck is running more smoothly and a little punchier. Probably placebo effect.
