What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[George B]

Thanks George, those look perfectly sized, not too big, not too small, just right!

They do work well.
I had a set of Husky molded ones but they would not work with my power boards and I figured would rub my tires. These are the same size and I used the layout for the husky ones to locate the holes in these for mounting. Slight mod to the boards and they clear by a hair.

Why did GM switch from the A/C tensioner to the Stretch-to-Fit belt anyways? The tensioner on mine works perfectly and was easy to replace as was the belt.

probably because of all the squeaky tensioners they have had to replace and 1 less part to assemble on the assembly line, less cost, that's penny pinching gm for ya

Probably less cost when building.

Also maybe to have one less pulley or spring mechanism to go bad and cause the belt to snap.

More than likely the first reason

Edit: Doubeleive beat me to it. I type slow on my phone.... Lol

Less cost and one less part to wear out plus supposedly less noise and vibration. They’re now used by almost every vehicle manufacturer for accessories like ac compressors, power steering pumps etc.

Pretty rusty pump.

How long did it take you to do the pump?

I have that Lisle tool also, but have never used it yet.

Since I just replaced the belt and tensioner pully on my 2001 the other day, (yes, it uses a tensioner pulley like the serpentine system does), I noticed that on my 6.2 there is threaded holes in the locations to mount an AC tensioner pulley. The AC belt on the nbs is a bit longer also, because of the use of a tensioner.

So I'm pretty confident that a nnbs can be retrofit with a nbs belt and tensioner pulley if someone wanted to

Thanks Wes! Hmm, now do I want to drop the headliner to do this? LOL

Utility knife and duct tape.
