Hello everyone,

On my 2020 GMC Sierra 2500HD Denali I did a hood air induction vent swap for a chrome vent cover and while I was at it I added Led RGB lights inside the vent taking care not to restrict the air flow. Has anyone else done any chrome or Led RGB mods? If so lets see them please.

GMC but they gave me one that didn’t have an open vent first and then I had to sit up there with them searching and finally found the one with the open vent. I tried to find you a part number but it’s in a pile of papers somewhere.

Was it difficult to mount the lights in the vent? I want to do something similar to my AT4 but am somewhat stumped on how to mount. What exactly did you use and where did you run for power?

Not to bad to mount. Hot glue gun to temp hold down wires and 100% silicone for more  permanent hold long term. The strip has 3m tape but you must alcohol clean good before install them. I also put a bead of the silicone on the sides of the strips to help hold them down. Drill a hole for the power on the right corner on the inside of the vent and seal with the silicone when you are all done. It can be tricky because you have to fish the power and ground wire through the hood channels and under the heat shield to the right hood hinge to travel back to the battery without pinching the wire. Don't forget the wire loom for protection. You can also get a module to control with your phone if you don't like the remote. I also am doing one for a guy with for $250 plus parts. See pics

You will need a 2 pin 16 gauge wire for power and ground and I put in a 10 amp mini fuse to be safe.

makes sense thanks.  i envision either running it off the power for park/clearance lights or just run power to one of the upfitter switches.

How did you end up removing the hood scoop vent?  I removed the 4 nuts on the underside and was able to pop up some of the plastic clips but wasn't able to get to three of them that were towards the center as there was no access to them from the underside.

I would like to know details on how you removed it after you took the 4 screws out.

For those wanting to know how to remove the Air vent on the hood (Hood scoop) on the 2020 GMC Sierra 2500HD AT4

 

Once you take the hood insulator off, you will need to remove four nuts. The two front ones will be easy to take off with an 8mm deep socket, the other two in the back will need about a 5in deep socket.

 

After the nut removal, there are 11 clips that hold it in place. You will need to pop them out. Most of them are not accessible from underneath.  So using a towel and some upholstery tools I was able to go between the hood and the hood vent, slide the tool over to were the clip was and with some restraining force was able to pop it out. The first pop was the scary one, after that I knew about what force was needed to pop them out. Make sure the tool is lined up with the clip. Out of the 11 only 1 clip broke.

 

Here's some pics of what the back of the hood scoop looks like and the upholstery tools used.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      By Jsdirt · Posted

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
