By far the best video I've seen on this procedure, hell this might be the best video I've seen on any auto repair! After watching a few others I didn't want any part of this repair but now I feel like it's no problem. Ordering the parts now.
I change mines two time now and the code keep coming up do I need to change the wire? Is there a certain brand that I need to use? How do you know how much tork to use?
I did mine about month ago it is showing same check engine light so I went and got AC Delco I guess these trucks get finicky with other sensors.
Doing this currently on my 2000 Silverado and the throttle body is a little different. I don't have any connect on the left side and it looks a little different. The cables are just moved out of the way for now but can't really leave the throttle body on in my case
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
My GM parts guy says Most Gaskets on the GM Engines are designed to be REUSABLE…….. 1999 and Newer
Thank you guys for your help with this information video. So clear and very informative ,save me tons thanks again appreciate you both best wishes
Do not try to bend the evap line like the guy in the video. Mine cracked off at the rear fitting doing that. Luckily it was repairable but it’s not a bad idea to have a spare evap line ahead of time.
Always replace both knock sensors,harness & gaskets u don't want to do all of this all over again
Great video, but it coulda used a lot more light.
Great video, links to step-by-step breakdown of how to to the job and buy everything you see/used in the video except–the intake gasket. If you're going to do all that for folks that may be doing this for the first time, would it hurt to put a GM part number or a link to one in the comments? Something?
