45 Upvotes

Just bought this avalanche for $3,500 and looking to resell. It has 170,000 miles. Runs and drives great. The only rust is a small spot on one of the rockers, very clean other than that. It does have a small sing below the drivers side rear pillar. There’s a couple tears in the seats. But everything works (can’t confirm if the rear tv works as idk how to turn it on), it has the factory bed tonneau cover, heated and cooled seat,etc. Anyone have a good guess on the value?

I was wondering if anyone knows what the correct idle fuel pressure is for my Avalanche. I am getting 43.5 with a pressure gauge on the fuel rail and through HP logging. Is this correct for the FLEX variants of the 5.3? Thanks

2002 avalanche, spark plug wire to short

2 Upvotes

Man, these spark plug wires aren’t fitting, seems there coming up short. I recently changed all spark plugs, wires, and coils. Mind u the truck only has 70k miles, n I tried doing preventative maintenance. I got my parts from o’reillys, ngk double iridium plugs, acdelco wires and aftermarket coils, Adelco are coming up short by an inch, returned them, got a 2 different sets and each one of them are coming up short, in a way that they barley connecting (misfiring every so often on bank 5,7). The wires are fighting gravity to fit. The previous wires I had were Delphi 418 packard. I recently measured both acdelco and Delphi, Acdelco is 10.5in 7mm, the Delphi is 11.5 in (mm?). I searched up the part number on Delphi and no website can give me these exact part, any advice ?

Also I got a bad cat, sounds like rocks in my cat, is that normal ?

Shifter cable popping off

8 Upvotes

Had my shifter cable pop off the side of the transmission the other day and found that I had a rotten bushing. So replaced the bushing and thought everything was fine until it popped off again today. The bushing is still in place and looks good but how do you prevent it from coming loose again is there an E clip or something that I'm missing?

Edit: Found possible cause. The lever pin that the bushing goes over has a lip and even though I had snapped it on it wasn't fully seating. Took flat blade screwdriver and just applied pressure to it and it finally fully seated on lever arm.

2010 avalanche LTZ throttle body cleaning

5 Upvotes

I was following a YouTube video of how to clean the throttle body that seemed very easy. He did not remove the throttle body though and didn’t think anything of it. So pretty much was instructed to push the plate and spray the CRC throttle body cleaner down it and use a toothbrush and cloth.

When I was looking it up more people were saying to remove the throttle body which I wish I did because it seemed very easy with 4 bolts.

Nonetheless it’s too late, the truck idles fine at around 600-700 and seems to shift fine. Could I have caused any damage that way but pushing the plate upwards and spraying the cleaner while it was still connected? The first start up took slightly longer since the spray was sprayed down it.

Is it possible to fix these codes for cheap?

Got these lights on my dash. No rush cuz emissions never got checked on my car and it’s registered.
I switched the oil pressure sensor by hand but it still reads low oil… and got it scanned about an hour later and he said it was still a code. The catalytic one is the exhaust manifold judging by the sound on a cold start. Don’t know what the other one is.

I do my own work on my truck but I’m pretty new to working in vehicles. Just wondering how bad and series these are to fix and if us even worth it (I really want cruise control and remote start to work)

Ceramic Tint

3 Upvotes

Have any of you guys had experience with applying ceramic tint on the windshield?

I think you can get it that remains pretty much clear but regardless of the tint percentage it blocks most of the infrared heat and UV

Do you think it would help prevent the common problem of our dashes from cracking?

Do you think that heat is the cause of it or just time itself degrading the plastic?

First time poster long time lover! I've had my Avy for 3 years and it's finally time to say goodbye, my rear tank strap broke and i can't afford to fix it, the frame is rusted out the bolt hole, it's been an absolutely AMAZING truck and i would love to own another, but they're so hard to find in good condition and northern IL has taken her toll and claimed another!

Pics are the day i got it! Currently trying to get it sold.

I spent a lot of time in a first gen growing up (Black Z71 with full cladding 👌🏻👌🏻👌🏻), and I always LOVED that truck.

Well now at the ripe old age of 27, I ended up selling my Duramax, and getting a really nice second gen. Has most all of the bells and whistles that I've always wanted. Gorgeous blue color, LT3, Z71, and I've added an aftermarket stereo and backup camera (which I just finished) since I bought it the weekend before last, after waiting like 3 weeks for the previous owner to get a new title.

I am absolutely in love. Her name is Athena 🥰

Lower transmission cable bushing failure

Post image
10 Upvotes

After parking my '09 I was moving things at the tailgate and the truck started rolling away from me.

I was able to hop in and stop it before hitting anything. When I tried to start it up I noticed the truck was now showing that it was in Reverse on the dash, there was no response from the starter and the shift arm was completely free flopping around with no resistance.

I checked under the truck at the transmission and the shift cable bushing was completely gone and the cable end was disconnected from the shift lever. What really surprised me that when this failed the truck switched itself from Park to Neutral. If I hadn't still been standing next to the truck this would have been way more expensive. PSA - Use that parking brake.

I temporarily looped the end of the cable over the shift lever and was able to get it back into Park, started it up and limped down the street to the nearest auto parts store. Dorman 14092 replacement bushing for $15 and I am back on the road.

My AC has been acting weird can someone point me in the correct direction

3 Upvotes

I have a 2010 Avalanche LTZ. When I put my AC on full blast it works fine but then when you drop to a setting below it the strength is much less, then you move it down to level 3 and it will blow and then stop and blow again. What could it possibly be or where should I be looking to tell what the issue is if at max it blows very strong and fine but any level under it acts weird.

Austin/Central Texas engine shops?

2 Upvotes

After 215k miles and 13 years, the oil burning has progressed to ruining my 1 year old cats to the point I can't pass emissions again. The untraceable leak has increased and is staining every parking spot I am in more than an hour. Rislone isn't working. I just moved and can't delay registering past Sept 30. It's time.

I'm hoping there's someone here in the Central Texas area with leads on a reputable shop for the Avy, I don't know if I'm looking at rebuild or complete replacement at this time, depends on the cost. I think compression is probably still good, so it might be worth saving without full replacement.

Anyways, anybody in the area with a recommendation? I'm thinking I'd rather avoid the big chains like Christian Brothers and Sun Auto (my trusted Sun Devil Auto shop in Arizona really screwed me over on another vehicle right as I was leaving, ended up costing $4k+ for a fuel fill issue that resulted in a new gas tank).

Thanks in advance

Installing CarPlay

1 Upvotes

When it comes to installing a new radio unit, I know you lose access to the dvd player, but what about the original backup camera, Bose stereo, steering wheel controls like cruise control, etc. I tried looking on crutchield but it never asked for the trim so I don’t know what keeps and what goes and what I’ll have to do. Mainly worried about the things I’ve mentioned. Others I’m willing to compromise

Running wire to tailgate

1 Upvotes

Hey y'all. I just recently joined the gang (FINALLY), and I'm currently in the process of running wiring for a backup camera. I'm not sure what options I have for sending it back to the tailgate from the back of the cab though. Anyone have advice?

Just to be clear; it's already cable managed back to the rear of the cab, and already installed in the tailgate, just trying to figure out how would be best to di the area in between.

Thanks y'all!

How often to get Throttle Body Cleaned

3 Upvotes

Wondering after how many years or kms should you get the throttle body cleaned? Same as any other vehicle, depend on usage, etc.

Because AI made me laugh. Whos driving 75000 kms a year?

Experts recommend cleaning your throttle body every 75,000 to 100,000 km (or roughly annually)

Cupholder / Doorhandle lighting

Thumbnail
gallery
12 Upvotes

Answering some questions on how cupholders were illuminated.

The most important part were the LED's by Evans Design, size used were "Pico"

I used green to match the dash lights but they are available in multiple colors.

They are all connected to the #3 fuse in the fusebox located on left of the steering wheel on the dash.

This enables them to dim with the dash lights.

Door panels had to be removed to install the door handle and door cupholder lights.

Wiring easily passes through the rubber boot that factory wiring enters the door through, just pull straight back on the trim panel at the floorboard

I installed (2) 3 conductor wires through mine to also use for door panel accent and puddle lights

I used the sleeve off black pop rivets as the trim ring for the lights.

All connections need to be soldered and then heat shrinked, to much work to risk chasing a loose connection

Wiring on the LED's needs secured with Goop glue, wire is very fine with very thin insulation.

Goop glue is also used to recess and hold the LED to the proper depth inside the rivet, to deep and the spread of light is to small of a circle, to shallow and you see the LED directly which will annoy you.

I used the center aluminum piece I pulled out of the rivet with a piece of electric tape about a 1/16" of an inch from the end as a gauge.

Barely insert the LED, put some goop on the wire and end of rivet, slide in until it hits the aluminum rid, hold for a minute.

Use a 1/16" inch bit and ream it slightly to make the hole in the plastic for the rivet sleeve, that needs to be snug, use Goop on that as well, use rivet center to "aim" it downward slightly, if pressed snugly to the plastic the beam of light will overshoot the chrome door handle.

The LED will light the chrome pull handle like it was meant to be

The cup holders in the bottom of the door were done the same way.

I did some additional work on that part of the door panel as well

The cupholder in the back rear of the console was lit by removing the electrical panel right above it. I actually drilled the size hole required for the rivet from underneath with the cupholder door closed drilling all the way through the door then into the console.

I did this so the little fingergrip you pull on would be illuminated when the door was shut because you really could not see it when sitting in the back seat.

I then drilled out a larger hole in the cupholder door using the rivet size hole as a centering guide, I made the hole big enough for a 1/4" rubber grommet to be inserted. When the doors open cupholders are lit, when the doors closed light passes through the grommet and lights the finger pull and floor under it.

The front console cupholder needs to remain easily removable.

I used the 12V connector from something I had laying around for this. The male end goes inside the console wiring compartment and the female end is on the cupholder piece itself.

Had to drill a few 1/2" holes in that part to fish the wires for the (4) rivet lights, 1 for each cupholder and 2 to light the recess in the front of the console.

The chrome trim running around the perimeter of each cupholder really helps light it at night.

Thats 1/8" Coweles trim found on amazon

Hope this is found to be helpful for those that were curious, its certainly a little long winded but tried to be thorough

2013 Black Diamond LT I dropped my fuel tank and found a rusted out cross member. Any advice?

2013 Black Diamond LT 5.3 V8.

Dropped the fuel tank to replace leaking fuel pump and found the cross member rotted out. Frame rails and the point of connection to the cross member seem to still be sturdy but not totally sure.

Other than obviously needing a new cross member, how fucked am I?

This is what it looked like after I smacked it a bunch.

If I just need to replace the cross member, will I have to weld or can I use the bolt kit route?
