7th Gen ('06-'07): '06 Charging issue

'06 Charging issue
So last night on the drive home, about 25 miles, "Service Battery Charging system" or something to that effect came on, and battery light. Drove home, it was late and I was exhausted. Made it and car restarted fine, lights etc all fine. I had heard a high pitched whine that increased with engine speed for a day or two, so I suspect the drive belt may need to be replaced, 150K miles and not sure if it was ever replaced. So, for this belt tensioner tool EN-47988, is there any other way? I'll check with Autozone and see if they have it available to rent if not....thanks guys! I'm also thinking of just heading to the local DIY shop and being ready in case the alternator is the actual issue.

You shouldn't need a special tool . Most GM tensioners have either a square slot for a 3/8 ratchet or a nut that you can put a 15 mm wrench or socket on to remove the belt .I would guess your 06-07 is the same. I would also suggest that you spin the alternator pulley and listen for noise's like a bad bearing. Good luck

The parts store will have the correct tool to borrow. It's a 3 foot flat bar with a slot that holds socket or square drive adapter. Quick note if there isn't a belt diagram under the hood take a picture of the routing to save a hassle later.

There is a special tool to remove the belt for the 5.3s in the SS's. A normal belt removal tool that most are familiar with will not work due to the aforementioned clearance issues. I had a squeaking belt and ran into the same problem on my 06 SS. I tried every way under the sun and moon to jimmy my standard belt removal tool in there but no joy.
I however use to work for local gm dealer back in the day and stopped by and borrowed theirs and 10 min later a new goodyear belt was on and I was on my way.
Autozone or advance may have one to loan I never checked myself.

Autozone had the tool -cheapest I've found online is $75:

Free > $75 lol

Get the narrowest crowbar you can find. Take off the passenger side wheel and the liner behind it. Then put the crowbar on top of the tensioner and push down.
This is a lot of effort, but $10 is a whole lot cheaper than $75.
