Time to change the alternator, but I have to get that serpentine belt off first. On a lot of cars I see a place where a 3/8" socket will go directly in and turns to release the tension, but I'm not seeing that on my F150. I tried putting a socket on the bolt in the middle of the tensioner spring, but I just seemed to be loosening the bolt. I stopped before I launched something into the air (or into me ). How do I get that belt off?

I am suprised there is not a place for a ratchet. I have used a pry bar before, or a crow bar will work. Get the bent end behind the pulley enough to hold and pull back releasing the tension.

Ummm.. a 14mm socket on the tensioner PULLEY bolt will allow you to release the tension.....

Good pic. That was rather easy. I had though of trying that, but after the bolt on the spring started coming out, I was hesitant to try the one on the pulley.

Alternator is off, so I'll get it tested tomorrow. I'm 90% sure that's the problem. Gauge stays below the N in Normal and the red battery light is on constantly.

Speaking of tensioner pulley's, I just replaced mine today. Piece of cake. I also replaced the idler pulley while I was there. I never realized just how noisy they can be when they're going bad.

It's a left handed thread on that bolt...by attempting to release tension on the pulley, you'd be actually tightening it.

i got 3 alts on my 5.0, a breaker bar with a socket will get the tensioner loose

Wow. You sir just made me lean forward in my chair! Is that for real? How's the hood clearance? I'm not even sure how you route that belt!?! looks like the steel bracket locating the idler pulley would be in the way...
I hate to ask what equipment you're running that would require 3 3G alts...

EDIT: my bad, I see you only have 2 3Gs, and one stock 2G! LOL!
