I have a 07 TB LT with a 5.3 LH6 engine.. The engine is shot i found metal shaving under neath inside the oil pan the truck dis not over heat it just stalled on the hwy and didnt turn over. Tried spinning the fly wheel but no look it is out. What would be my cheapest way to fix this? Simply purchasing another engine (ard to find and expensive) or buying a short block and replacing? If there is any other engine that u know are capable of just quick replacing and plug amd play please let me know

I would suggest getting one from someone parting out a vehicle, LH6's seem to have been used in 1500's for 3 years, so they shouldn't be that rare...  Shouldn't be that expensive either.  At least not if you are near any major city.

 

Personally, if I was really happy with the condition of the Trailblazer (everything works, not rusty, drives well, it's a vehicle I like), I would buy a cheap engine, even from a junkyard, slam it in there just so I could drive it around, and then take apart the bad engine, see how viable the bits are for rebuilding it, and either rebuild it, or buy another cheap engine, and rebuild that one to eventually be the 'good' engine.  But I have a garage and a good selection of tools, so it's a reasonable option for me....

      I recently acquired a 1951 Chevrolet 6100 missing its engine and would like to refurbish it. However, Instead of putting in the original engine (Chevrolet 235) I am looking for an engine that came out in the next 10-15 years to put in my truck that will out put 200+ horsepower without being out of touch with the truck. Any advice would be greatly appreciated.

      Hey Guys,
      I have the opportunity to pick up a 2019 5.3 engine & transmission with 20k miles on it fairly cheap. I have an 09 sierra that I'd like to swap it into, currently running a stock 5.3. My question is:  Is it a big deal to make a change between years like that? I've replaced engines before in older trucks but never with this type of age difference, I don't want to get in over my head.
      Thanks!

      Hey everyone, I picked up my 6.2L 2020 GMC Sierra AT4 about 3 or 4 months ago. I haven't gone ham on it or anything crazy, mostly just normal in town driving, a little highway driving,  and one 400 mile trip on the interstate & highway pulling an 18' enclosed trailer (just helping someone move, so the trailer wasn't heavy; just furniture and stuff, not snowmobiles or anything heavy like that). The truck only has a little over 2,000 miles on it. From the beginning I always thought the engine sounded kind of weird, had like a ticking or clicking noise to it. Everyone else told me they couldn't hear it, and said I was crazy; until yesterday one guy said it sounded like my engine had a tick. Can hear it the most once the engine is warmed up. I took it to the dealership and asked them about it. They said in older models it'd be a sign of lifters going out, but in the new models that it's normal unless it gets any louder or starts sounding more aggressive.
       
      I'm kind of a little nervous since my brother just found out in his 2015 GMC Sierra All Terrain his fuel pump is leaking and letting gas into the oil; he first started noticing the problem when his mpg started going to crap a couple years ago, but the dealership kept telling him it was just the fuel blend in the winter time, even though it was happening year round. Finally he took it to a different mechanic (other than the dealership) and they figured out the problem really quick, and they assume it has been happening for a couple years now. Along with that they also figured out why his breaks would go out at low speeds, something with the vacuum system. To fix both problems was going to cost him about 3 grand parts & labor.
       
      I'm hoping mine isn't a mechanical flaw like what he found in his truck, especially not this early. However, I have had to bring my truck into the shop 2 times already - once for a "service steering column" warning where they said the wiring coming unseated and they had to reseat it; and once because the infotainment system was defective and wouldn't turn on so they had to replace it; and yesterday I had a "service steering column lock" warning show up on the display, but I wasn't close enough to a dealership to bring it in so I'll have to wait for that one to pop up again.
       
      Has anyone heard that ticking/clicking engine noise on their 2019 or 2020 Chevy or Silverado? What the is it? It just doesn't sound normal.

      I recently installed the upgraded digital dash in our LTZ that did not have it thanks to White Automotive.  The process turned out to be quite a bit more daunting than I had expected. I had found a few posts (here and another better start here) that talked about upgrading the gauge cluster, however I could not find any specific step by step instructions to gain access. 
       
      With plenty of reasons for everyone to access the radio, center console, and gauge cluster, I thought a step by step tutorial would make the project immensely easier for anyone willing to do it. And trust me, If I can do it, you can do it. 
       
      This "How To" is in first draft form. I just wanted to get it out there for anyone who wants to do this or has been struggling with how to get the specific trim pieces that are required off. 
       
      Photos will be added to this tutorial after Christmas
      A Video will be added to this tutorial after New Years
      ---------------------------------------------------------------------------------------------------
      Tools needed
      7mm socket with 6 inch extension & ⅜ ratchet , plastic interior trim removal tools, T15 Torx bit
       
      Plastic Interior Trim Removal Tools are absolutely necessary. Using metal tools or screw drivers will 100% damage your interior!
       
      We used this kit from Amazon that costs around $16.  <------ This is not a referral link. Just being helpful and showing as an example. 

      Prepare by cleaning out center console, cup holders, charging area, side console storage areas, and by moving the front driver/passenger seats backwards. 
      Using towels, create a soft area to store interior pieces during work
       
      The Steps
       
      Pry infotainment decorative chrome/painted trim away, starting at the bottom around the HVAC vents on each side, then the top.  Remove square access cover directly next to the accelerator pedal.  Remove the 7mm screw under the decorative cover.  Place fingers in drivers side footwell console storage area and use moderate force to pull the side of the center console away.  You do not have the totally remove the panel. There are approximately 8 clips to pull loose towards the top and front of the panel.  Do the same on the passenger side, however there is no screw to remove before the panel will snap out. There are approximately 8 clips to pull loose. You do not have to totally remove the panel.  With the center console lid open, use a pry tool to pop the clips holding the top of the center console area to the center console assembly.  Pull up and disconnect approximately 10 clips around the cup holders, charging pad and/or storage pad area  and up to directly below the radio/climate controls. Do not yank the trim too far away, there are wires connected to the bottom of this trim piece.  Gently position the tray as far rearward as possible without removing the wires, or gently remove the wire connectors and place the console on your soft area.  Using a pry tool, remove the thin, curved piece of trim directly under the piano key switches. There are five clips to remove, each releasing directly towards the rear of the vehicle, parallel to the floor of the vehicle. Release  two clips on each side then pull gently to remove the center clip. Position console tray (if still attached) to remove two T15 screws at bottom of infotainment/climate control unit.  Unscrew top four T15 screws holding infotainment/climate control in place at top of unit.  Using pry bar, pull infotainment unit away, releasing approximately 8 clips around the unit. Use caution, HVAC ducting will come out with the unit, so only pull directly out.  Disconnect Unit or lean out to continue on for access to gauge cluster.  Using a plastic pry tool, release the leather infotainment trim, but only along the side of the cluster.  Using a plastic pry tool, remove the leather gauge cluster hood. The approximately 6 clips are released pulling straight up.  Remove the fuse access panel on the driver’s side door opening.  Using a T15 bit, remove the two screws holding the HVAC/switch unit in place.  Using a pry tool, pull the HVAC/switch unit directly away from the dash. There are approximately 8 clips holding it in place.  Unscrew three 7mm screws holding the front cluster trim piece in place.  Using your hands, pry the cluster trim piece away from behind the steering wheel, including the trim piece on the top of the steering wheel column that is attached.  Remove four 7mm screws holding gauge cluster in place.  For 2019 trucks, slide red locking tab and lift cam lock to remove cluster harness.  Reverse steps to reassemble.   
       
      Please comment with any suggestions, edits, or comments. I'd like this to be as helpful as possible.

      I’m trying to install new front end parking sensors to my 2016 GMC Sierra like @pgamboa on his YouTube video. Only not sure what todo with the front bumper, I’m trying to save money and not have to buy a new one with the sensor holes since mine current one is in excellent condition. Does anybody know how can I get the layout for the holes for exact placement and size? I figured I can drill them out myself but I’ve already looked everywhere online and can’t find anything on this. My last option would be go find a truck and physically measure them out, can anyone help?
