    Exhaust Manifold flange down pipe surprise!

    Was that the local pick and pull. Grabbed these manifold pipes for my LS swap. Have never seen these before. Is it some kind of emissions packing? Was off an early 2000s Tahoe. I guess I’ll hammer this stuff out. Going to make my own 2 1/2 inch y pipe into 3” single exhaust. No cats. Should...

    2003 Hydro Boost Swap Question …

    I have an 03 burb with vacuum brakes and picked up a wrecked 05 burb I’m using for an LS swap on my 84 Wagoneer. Was going to put the Hydroboost in my 03 but is the upgrade worth all the work? My vacuum brakes work pretty good but it could always be better. Did you notice a big difference...

    I installed E-fans on my 2001

    I was going to add a second battery but haven’t needed to since the new Sam’s Club battery has been just fine.

    2002 YUKON XL - Max tire size?

    Only thing with the mono max front shocks are they are too short unless you are stock height. I had to space out the front shocks running my 2” front torsion key lift to obtain 100% down travel. The bilstein 5100 are a little too long up front when you just have a 2” torsion key lift so pick...

    2002 YUKON XL - Max tire size?

    I've run a set of these silver bilstein 5100's and the red KYB Monomax on my lifted burb. The Bilstiens ride softer than the KYB and there is more of a floaty, boating, ship on the ocean stock ride. The KYB monomax are much stiffer initially but the burb still rides comfortable and not harsh...

    2002 YUKON XL - Max tire size?

    285/70/17 ~ 32.7" - 33" tire will fit with a torsion bar crank in the front. Here's my 03 Z71 with 1.5" rear coil spring lift spacers and torsion keys in the front. I had to change out the torsion keys up front as my torsion bars are a bit tired after 20+ years...

    Differential damage due to tire tread?

    Not an issue. Only an issue if you had the AWD transfer case like in the Denalis where you can’t select anything and it’s just always in AWD. Even then you may be within the limits of tread wear differentials. This would probably be a problem in Jeeps with the quadratrac transfer case. Those...

    Do yall use regular or mid grade gas in the 5.3?

    2003 suburban 5.3 LM7. 165k and it runs great! Sent all fuel injectors off and had them ultrasonic cleaned and they replaced the strainer baskets on each injector. Fuel trims look good now but can only get 15-16 at 70-75. Maybe it’s the 33” K02 tires because I pulled down 18-19 with the stock...

    Considering how GM screwed us with the oil, what about the ATF?

    https://a.co/d/01cMDOVt I ordered two boxes when I driveway flushed it. There’s several YouTube videos on how to flush yourself and check the level. Pictured is the old black label but as long as the seller and shipper is Amazon, I’ve received the blue label, which is the new fluid. Flushed my...

    Rear hatch won’t unlock or open

    Realized the top part is a separate piece from the bottom. Was able to pop the top part out enough to move the mechanism underneath it to unlock the glass and door!

    Rear hatch won’t unlock or open

    Removing the interior panel is not possible with the hatch closed? Looks like I’m moving this mechanism? Not my video just found one picturing the rear lock

    Rear hatch won’t unlock or open

    Rear hatch won’t unlock. When I cycle the door locks, I can hear the rear hatch mechanism locking, but nothing happens when unlocking. There’s no way to open it with a key. Both the rear glass and the rear hatch remain locked. Is there a secret release somewhere? I guess I could attempt to...

    Seal/Gasket Between Transfer Case & Transmission

    2005 suburban. Removed transfer case and a lot like 1/4 qt of atf poured out of the extension housing between the trans and transfer case. Transfer case was normal level with the blue fluid. 4l60e was rebuilt 40k miles ago and no issues. Is this normal? If not what seal do I need and tool to...

    Bose radio issues. No sound when cold. Randomly powers off for a few seconds.

    Yep, that’s the same thing mine does. Driving in silence, you get a loud crackle pop and then you get sound once the cab has warmed up. Earlier in this thread, I had heated the entire board of my original radio up to 360° with a heat gun. This solve the cold issue only for a week or so and...

    Bose radio issues. No sound when cold. Randomly powers off for a few seconds.

    Even with a completely different radio, which I soldered the security chip from my old radio on too the replacement so it wouldn’t be locked. I’m back to no sound until the cab warms up lol. So apparently common problem in this generation of GM radios. If I keep the radio indoors overnight and...

    I installed E-fans on my 2001

    @Matthew Jeschke I grabbed the fans and the harness from a 2005 Yukon XL

    I installed E-fans on my 2001

    I’ve successfully swapped my ‘03 burb to efans thanks to this thread and @ScottyBoy! For those of you that have a 2003 or 2004 GmT800 this is how I swapped mine. 2005 and up should already have efans. You’ll need a tuner to enable electric fan controls in the engine computer. I had mine tuned...

    I installed E-fans on my 2001

    I was at the junkyard when I posted the question lol. I pulled the entire front harness and small fuse box for the fans. I cut the tiny wires going to the main engine computer as there was no way I was going to pull the entire engine wiring harness lol. I have an extra computer plug so if I need...

    I installed E-fans on my 2001

    I’m about to do this swap on my 2003 suburban Z 71. I’ve already had the computer tuned by blackbear and they enabled the E fan support. I’m pulling the fans from a 2005 suburban do I need to grab the factory wiring for the fans from the donor? Or isn’t that useful?

    Instant MPG on cluster / DiC?

    I’ve used this guy several times. He is great and inexpensive. He rebuilds the entire cluster. New stepper motors, LEDs, reflows solder for the power supply. He loads the latest software onto the cluster, which enables the instant economy. https://www.ebay.com/itm/223082408139

    2003 Tahoe 5.3 Flex a dog when accelerating

    Lol. Yep tire diameter and weight definitely affect performance!

    2003 Tahoe 5.3 Flex a dog when accelerating

    I like the look of 33 but you can’t beat acceleration and mpg with stock tire size. Also I can feel the difference in unsprung weight between the two tires. Aka harness on bumps, expansion joints. Stock tire is prob 35-40lbs per tire and 33” 55-65lbs per tire. It’s not a huge difference but...

    2003 Tahoe 5.3 Flex a dog when accelerating

    You will notice the acceleration drop going from stock tire size to 33" (285/70/17) It's not terrible but my tuned burb has to downshift a bit more if I drive 70mph or lower on the Interstate than with the stock tire size. I have 3:73 gears but picked up a wrecked burb that has 4.10's! A big job...

    3.0 vs 6.2

    I have the L86 6.2 AFM before they went to DFM in the L87. Love the 6.2 exhaust note and getup and go power! I’ve even got 22 mpg at 70mph on flat intestate for an entire tank. Tows my 4k lb 16x7 enclosed trailer like it’s barely there and puts a smile on my face when it gets in the revs. That...

    Leaky axle seals? and everything else..

    I probably added too much to the Audi gearbox when it didn’t slow the leak then the leak got worse when the seals over swelled. I added it to the crankcase of my 97 vortec 350 for 1 oil change. Didn’t slow any of the leaks. Didn’t make any of them worse. Ended up replacing oil pan gasket which...
