Total mechanic newbie but knocked this replacement out of the park yesterday. Couldn't have done it without these gents and this superbly made video. Cheers!!

Just did mine today while watching this video step by step. Really helped a lot. Not that hard of a job, just a lot to take loose. I did go a step further and put new intake gaskets in and permatex around the covers on knock sensors. Thanks for the video

Not at all - it looks like a handful up front but take your time and most people should be able to do it

Thanks guys. I'm about to perform this exact repair on my 5.3 and you have by far the most clear and thorough step by step guide I've found so far with the best camera angles too. I will most certainly be referring to this as I work. One other detail worth mentioning is that GM has a technical service bulletin out about the knock sensor replacement. They recommend removing the foam seal on the rear side of the intake manifold visible at 14:25 in the video upon re-installation. This is to allow any intruding water to easily drain out the back. Also, they suggest placing a dam of RTV sealant around each knock sensor hole with a small opening facing the rear of the engine to further prevent water intrusion. Cheers.

swapped out the oil pressure sensor and intake manifold gaskets while I was at it and really cleaned the block being careful nothing got in those holes and even then, took me about 3 hours. just pausing a playing the video going step by step! you guys are amazing!

While you have the intake off, consider replacing the oil pressure sensor. Especially if it’s pegging out at max.

These guys are great!!! I just used their list of steps to work on my Yukon. I checked off the list step by step so I didn't forget anything. It went great!! Thank you so much for a great video and I loved the check list. You guys rock!!

This is a great video. I have watched several videos on replacing the knock sensors. Your video had all the fine details and very well explained to make the job easier for someone to do this. I really like that you explained the socket sizes needed and torque specs. Saves someone time digging thru the tool box and trying sockets to find the size and saves time looking up the torque specs. I'm about to do this job shortly on my truck. Thanks.

Thank you guys for a very informative video. After watching a couple of times I was able to get this job done in just under 4hrs. Not to bad for a carpenter. Top notch step by step instructions. Thanks again!!

3 steps. Thumbs up. Subscribed. Click bell icon. I gotta do this job on my '02 5.3L Silverado. I've been watching dozens of "how to" videos for the last 2 weeks and I must say that this video is hands down the BEST VIDEO on this subject. Thanks. Great camera work.

Thanks so much for this video. I was not wanting to pay to have this fixed, but the job seemed daunting. It wasn’t simple, but your video seriously helped so I could do it. I did replace the manifold gaskets, cleaned out the throttle body, replaced the knock sensor gaskets in the valley pan, replaced the valley pan gasket, and also replaced the oil pressure sensor.

Great video, my friend and I followed it step-by-step on his '04 Suburban 5.3L and were very successful, almost couldn't believe how well it went.

I just completed this repair on a 2006 Tahoe. This video was spot on and really helped me to understand the proper techniques. After purchasing the sensors and a few tools, I completed the job in about 3 hours, including a few breaks. The rear connectors on the injectors were a real bitch. I would recommend disconnecting the negative terminal of the battery to be safe.

👍🏽 did it myself no issues. Recommend replacing wire harness.

This is the second time that I have used this video to replace the knock sensors. Thank you, guys, so much. I am hoping that I never have to do it again. Plus, all in all, with your help in the video it took me back to the days when I loved working with cars, most of all my 41 Chevy Special Deluxe Coupe. Thanks again for the detailed video, it will give confidence to those that might not have all the courage to jump into this type of project. 3/19/2022

I just performed this repair on my 2005 Suburban 1500 LT 5.3L. Took about 2 hours start to finish. This video was exactly what I needed! I took my laptop to the shop, watched some of the video, paused, then performed the task. At first I was fearing the fix, but after I got into it, it flowed like milk-n-honey. I did use some Red RTV Gasket Maker on the knock sensor wiring harness rubber gasket. I also replaced the manifold gasket. You guys did a great job with this video! Fear no fix!

THANK YOU!

Honestly never work on my cars and just by watching this video step by step I was able to complete this repair! Thanks

Superb video. I will probably have to tackle this job soon on my '04 Silverado. (DTC but no check engine lite). I am so thankful you guys took the time to explain it all in such perfect detail and with nothing unnecessary (unlike so many videos). Thanks again - great job!

I'm tackling mine next weekend! Your video gives me the confidence to do it. And step by step instructions! Thanks a ton.

Thank you guys for knowledge. Just got done doing this project on my 2000 Chevy Silverado. Really not a bad job. Did everything like you suggested and turned out great. You are great in detail and recommend this video for anybody with one of these older Silverados or vehicle with the 5.3 vortec. Thanks for your help. God bless.😊

Nice and informant. I had a few other items on my 2001 5.3. ERG line and throttle/cruse cables. Service engine light still on. I'll for information to clear. That was a lot of work. You guys really helped me out.

I just did this repair today it took me just under 6 hours. Well worth the time to do it myself. Had to remove the valley cover for the back knock sensor was rusted on tight so I had more work added. After I was all done my truck runs so much better. Made a big difference in engine performance. Still need to get the code cleared. Thanks for the informative video.

Great video guys; even my wife was impressed. I did change my intake gaskets because they " crushed" unevenly on one or two intake ports and i thought it would be prudent to go ahead and change them. I did have to clean a lot in that area since i have 263,000 miles on it . thanks for a great video.

Thanks guys, followed this one for my 1st time removing the manifold on an ls. Found tons of oil in the manny but didnt have the ls6 valley cover to fix it for good. Plan to pop her open again down the road, cant wait to cut my time in half!

Great video, it helped me a lot with my 2007 Silverado classic only difference was injector harness. I did have an issue where the rear knockout sensor was rusted. I wasn't even able to put a ratchet on it. It got so bad where the top was basically missing. It only left the knockout sensor body walls and threads to the engine. I ended up removing the "valley" so I can remove the rear sensor. Besides the rusted sensor this video was very helpful. I would recommend to add RTV sealant to prevent water to get in the sensors. Again great Video!

Great video! Really helpful! Got it done in four and a half hours!

You guys are Amazing Very informative and helped me fix my sensors without missing any step.

This the real deal here. Was thinking on taking it to a shop, since i don't have too many tools. But after watching this, i'm just gonna buy what I need and do it myself. Awesome video. Screw the thumbs down.

I would never put it back together without cleaning everything - especially the valley pan and other stuff not normally accessible. Nice job.

Friendly tip. If you do this its wise to replace the harness at the same time. Over time the heat cycling of the wires can make them brittle. It would be a shame to have to do this again because a wire broke a month or 2 later. Also I highly recommend to stick with AC delco sensors

I just performed this on my 2004 silverado, hardest part was removing the fuel line (becuase i didnt have the special tools) and disconnecting the 2 hoses under the throttle body. other than that it was allot of fun and easy, re assembally is even more fun and allot easier than disassembly. One part in this video i saw was to prevent future corrosion to that back knock sensor is remove a small foam piece in the back top of the intake manifold.

thiis is a fantastic video explained extremely well, i just pulled this code i will take the weekend to do this job thank you for this video

Definitely emphasis needed on INCH POUNDS for the intake manifold bolts. First one I set to 44 ft lbs like a complete dummy because I wasn't paying attention enough and sheared it right off. Yay!

love the video 🙌🙌but the way he handled the evap line 😭😭😭we know damn well our shit gone snap if we do some bending like that 💀💀💀

Video really helped, what didn't help was when I snapped off the fitting behind the throttle body, then had a literal rats nest under my manifold, and then I had to pull the lift plate to get to the back knock sensor and then had to use a special extractor tool because it was rusted to shit. But, I really do appreciate yall.

Thanks for the video. It really helped me do the job my self. $56 each sensor at Autozone $126 for both. Lifetime warranty. There’s was only one problem I ran into during the process. Last sensor was rusted and corrected. The first sensor came out easy and looked new. The rear was not to good. I said dear god help me get this off with out issues. I gently press down with a 22 mm socket and waaala. I was thinking the worse when I seen that sensor in bad shape. The clips that snap to the sensor broke off as I tried picking up the plastic plug. But I manage to make it work with out changing the harness. I sealed the black plugs to prevent moisture with the single middle wire. I also had to unplug the gas line with a small screw driver. Didn’t have the tool. I now need to reset the check engine light and hope it stays off. Thanks for the video. I saved easy $600 to $1,000. Maybe more

Very detailed video you guys rock! Thank you for all your help and knowledge. I’ve seen on one video this person cleaned the knock sensor holes and blew compressed air in before replacing them. Do you think that’s necessary or extras? Also, he placed a lot of silicone lines to try to stop water from going in the knock sensor holes. 🕳 In addition, he removed a foam padding because it holds back water or antifreeze if one of radiator hoses ever broke. That’s how the sensor starts rusting because of the liquid that stays in there 🕳 . It eventually evaporates but still damages the material. You guys are the pro though let me know if that silicone thing is effective or not?

Terrific video. Thank you and your staff for the step by step instructions. QUESTIONS; should you replace fuel injectors while doing this repair? Should you replace the intake manifold gaskets with "Fel-pro metal snap-in gaskets (heavy duty) or the standard snap-on gaskets that came with the engine? Finally, should you replace the oil sending sensor and the crankshaft sensor when you have the intake manifold off? Thank you for our quick response.
