'96 Serpentine Belt Question.

3.8L
I am using this diagram from Autozone:

The old one snapped off.
I put the belt on, am 90% sure it is on correctly, but I cannot tighten it. Am I supposed to tighten the bolt on the Drive Belt Tensioner Pulley (#4) or do I need to get to the Drive Belt Tensioner (#7) to tighten this bad boy?

I have tried to tighten #4, but it seems to make no difference, and seems like it is just there for routing purposes.

Hi
If you have threaded it properly, you should have a very difficult time pulling it over the last pulley. If it is loose, you either do not have it around all the pulleys or you have the wrong size belt.

Thanks, I will recheck the threading. I have double checked the belt on Autozone's website.

Hi,
from the topside of the engine,

get a 15mm wrench onto #7 ready to pull toward the front. (clockwise from Passenger side).

Get all slack directly above #1.

Pull wrench on #7 toward the bumper, hard! (with your right hand.)

slip belt over #1. (with your left hand)

Should #7 be free moving? Meaning, should I be able to turn it by hand like the other pulleys? If so, that may be the problem. It doesn't move at all.

That's the problem! Good for you!
