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

you can get it from the rear passenger door area, you will have to pull it down enough to reach in there and unclip it, you might have to pull the plastic trim between the front & rear seat pillar back some I was in mine before it will all tuck back in fine, just make sure your hands are clean the head liner likes to take finger smudges pretty easy, take your time and go easy it's just a cardboard form

Oh also not impressed with the slotted rotors i have. The slots rusted and filled in so it shakes when i hit the brakes going from 50-slower.

when it rain it ***** all over you

that blows
i never had that issue on current or previous vehicles using slotted rotors.

only issue i had was w/ cross drilled rotors.... they tend to crack more w/ hard driving.

That must smell....

Chased some tire rub in the front. Trimmed my mud flaps and adjusted the liners should be good now.

I noted considerably more brake dust in the front that the back. I recently replaced the back brakes with Raybestos Coated rotors and ceramic pads. Considering the fronts however they are in almost new condition. Is it worth it for the dust factor? The kit is $100 on RockAuto...

Edit: The pads are ceramic semi metallic hybrid pads.

good ceramic pads should make virtually no dust

Yeah, really impressed with the rears. Its all basically road dust. The fronts have that classic brake dust Brownish black Hue to them.

Over the weekend I changed the oil, oil filter, serpentine belt, ac belt (this was the worst thing to do, by far), rear air shocks, and rear air suspension compressor.

Hoping to get the transmission fluid and filter changed in the next few days.

Also order some other goodies: new Husky front and second row floor mats, Hikari high and low beam leds, and.....a new “Chevrolet” keychain

THe AC belt gave you trouble?
I have this little tool and it works great. That belt was easy to do.

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

Actually there is a NNBS tensioner because my 08 Silverado has one stock. P/N is 12580196 but then you would need the belt too P/N 12576447.

It's summer, too hot, rainy or they're on sleepovers. Oldest two are back to working and youngest is away at summer camp. Winter project! Still have to swap out the Onstar Antenna.

Which kind do you have? Any photos?

2007s and I think 2008s also used the tensioner.

Yeah, no one had that little tool in stock so I did it the hard way with some ingenuity. Whipped me good and I have the bruises to show for it.

The first attempt wound up with the belt on the crank pulley beautifully, but realized it slipped off the ac compressor pulley and pinched between the compressor housing and pulley. I had to cut if off and go buy another one to give it another shot, but the second time worked.

it sucked. I’m ordering the tool to have for the next go round. Ugh.

@swathdiver I do in my thread. I used some flat plasticolor flaps.

They work pretty well, are low profile and I could use them with my power running boards.

I did the big brake job today. Rebuilt all the calipers, installed new hoses, new rear rotors, machined front rotors, and all new pads. Wow this was one HELL of a job. I will never rebuild a Caliper again. It’s just not worth my time. The labor to clean and paint them wasn’t calculated into my plans. I bet I had eight hours into this. Here is the best part - I did the Tech 2 Automated bleed and I ran out of f****** fluid! Unreal. I bought all the parts from RockAuto with the exception of the left rear Caliper which I had to buy from AutoValue as the frozen slide pin head snapped off. These were all original calipers with 140k on them. Hell, all but one of the Caliper slide pins were frozen (besides the one that snapped). Nothing the oxyacetylene couldn’t handle. I thought the brake hoses would be a challenge but using a propane torch to heat up the female fitting on the old line was enough to let the 13mm flare nut wrench do it’s work. Never again. Quality reman or new calipers ONLY.

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

 

[cfmistry]

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.
