This to me seems like way more corrosion than even possible from one rain storm and only 2 months of being out of the package...I guess it is what it is and I payed the 250 to get things back under way...was just glad to be done with that customer service department...anyone buying fast products be prepared for that end of those guys....

 

Next I was on to the alt. And power steering bracket off of the 5.3 as I decided to keep all of the 5.3 accessories for ease of install...the factory belt idler pulley location was cut off of the bracket like so..

This section of the bracket was removed to clear the lower throttle body position of the 6.0 intake....the idler pulley was then moved to the right pretty much right under the alt pulley...I used one of the bracket mounting holes for the new location of the pulley...what I did was I found a larger bolt and I threaded the bracket hole...I had to enlarge the bushing to the pulley to except the larger bolt...I then threaded the alt bracket hole to accept the larger bolt...correct spacing was then the next issue... I have a lathe so made my own spacer...

The pulley was then installed and the bracket mated to the block...

The water pump from the 5.3 was used and the water outlet had to be flattened toward the t-body to allow clearance for the throttle arm... the top of the pump had to be shaved slightly as well to clear the bottom of the t-body... then it was on to mounting ac bracket and pump from the 5.3....that stuff bolts right on...also had to use the 5.3 balancer as the 6.0 balancer is much shorter...

 

In this time I received the new ecm from fast and proceeded to install them inside the cab due to them not being water proof like they said they were...post-166987-0-15138900-1483207868_thumb.jpg

 

I then took a piece of steel my customer had and cut out slots for the wires to pass through..then installed the plate over the factory 5spd shifter hole...

Soon we will be ordering a automatic truck replacement carpet to cover the ugly steel plate that looks like a 8 year old painted...

After that was done it was on to making the gto covers fit the engine again...this was a time consuming task...more so on the driver side because of the 5.3 alt and bracket being mounted so high... but they came out excellent...post-166987-0-83540000-1483209519_thumb.jpgpost-166987-0-82982300-1483209540_thumb.jpgpost-166987-0-58462900-1483209604_thumb.jpg

Then I installed the gto electric fans..the housing needed to be slightly modified to sit flush against the silverado radiator..I then started making the fan harness and putting together relay pigtails...the fast ecm has negative output to control fan 1 and 2...the rest of the pigtails were hard wired to 12 volt switched and 12 volt constant with the use of some 40 amp fuses and holders on the 12 volt hot side..all of the silverado radiator hoses were reinstalled as well..post-166987-0-63796800-1483209929_thumb.jpg

At this point I was back to a little wiring...both the fast ecm and the truck bcm require a temp sensor to operate the dash and fast ecm...after many hours of contiplation on how to piggy back the wiring it became so blatantly obvious I was way over thinking this... the easy solution I came up with was purchased another temp sensor and installed it in the passenger side head...it was so obvious and I over looked it...oh well...lol... so the fast ecm is controlled by the sensor in the passenger head and the dash is controlled from its factory located sensor....

It was now time to find a nice place for the fast handheld/programmer.... the kit came with a bracket like a GPS that clips to the handheld and suction cups to the windshield... I was not particularly fond of this idea for the simple fact when it's not Hung on the windshield being tuned it leaves this ugly data cable and connector on the dash making it look just hacked!.... I then realized I found my mounting spot...right where the passenger airbag bag switch is in the dash...the hole is slightly smaller than the screen of the handheld but leaps and bounds nicer looking than the windshield mounted way....I proceeded to pull the dash apart and remove the airbag switch...I pulled the wires for the switch back and routed them to the glove box...the switch will be mounted inside the glove box door so it can still be used....the handheld wiring was routed up into the dash to the stock airbag switch location and the handheld was then place in the hole...the dash was then reassembled....post-166987-0-87055800-1483212762_thumb.jpgpost-166987-0-45291200-1483212792_thumb.jpgpost-166987-0-28427400-1483212830_thumb.jpg

The last step of the build was to address the steering column mating bolt and nut...the kooks headers are 1 7/8" primary tunes and the way they were built one of the primaries was so close to the steering shaft that I could not use the factory bolt and nut for the silverado.. so I was off to improvise.... after many ideas later I came up with cutting the shank of a bolt and using that...

 

post-166987-0-10464700-1483213413_thumb.jpg

 

As you can see I cut a section out of the shank of the bolt...the column is 1" thick..I went with .950" so it's. 050" shorter.... as you can see I then drilled and tapped the piece on each end to accept 6mmx1.00 button head allens to allow for clearance...I then used 2 fender washers and cut them on each side to make them just thinner than the flat sides of the column...

I then held the shank in the vise.. put some red loctite on my Allen bolt and snagged her up....this will be the permanent side of part....then I simply slid the part on the hole of the column and installed my other modified washer and my other button head allen... I put loctite on this bolt as well but lesser strength blue...

 

post-166987-0-37806900-1483214032_thumb.jpg

 

As you can see I didn't have much room to work with so this idea was by far the best solution... the shank was made .950 thou. To allow a crush effect when tightened just like the factory bolt... some might be thinking wow that's small how tight could it actually get...well the bolts are stainless, and the shank was obviously a hardened bolt so I can lean on it pretty well....

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      Navigating senior years.

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.
