Just did this repair while I watched this video. Took 7 hours, 2 trips to the parts store to get the right tool to remove the fuel lines. I broke one heater core hose and the PCV vent hose, another trip to the store. But the transmission shop was going to charge over $800 to do this. THANK YOU! My truck runs great again with 226, 000 miles

Took me exactly 2 hours, bought all tools and parts suggested and
It went perfect . Followed and paused video as I moved along. Thanks!

Just did this to a 2006 Suburban. It was really easy and I also changed out the cam shaft position sensor as well as oil pressure sensor. Figured I might as well since I had access to them. I also put a bead of silicon around the rubber boots of the knock sensors to help keep water out of them. Overall the job took me about 3 hours and I’m fairly new to working on my own vehicles.

I love how 26 minute video is gonna turn out to a five hour job for me😂😂

One of the best mechanic I’ve seen on YouTube by far, well explained and very experienced as seen. Awesome video

[MrBlueBerry]

Followed this entire tutorial step by step, huge help! No code, no check engine light!

Every time I watch a repair video like this I think to myself how much I miss carburetors.

Just did this for my construction bosses truck with 420, 000 took 3 and a half hours, the guide was amazing. Was able to get the parts I needed and prep was super easy next times going to be alot less confusing

[moisesvaldez]

Great freaking video. Like how he's reading out the size of sockets and tips he gives as he's going along. I gotta replace my knock sensors on my 2004 Silverado and this will definitely help.

finally a vid that shows how to disconnect the plugs, ty

[davidProvins-hb]

This video was precise and well documented and informed. Other video's didn't show the level of detail like this guy does. 5 out of 5 stars

just finished, took about 2 1/2 hours maybe 3. Really simple. Would have been faster but one of the sensors was rusted and I took a few breaks cause of the heatwave. Thank you so much for the video.

[MrDavedep]

It took me just over 5 hours. I stopped for some water breaks but mostly just kept at it. Thank you for a great video! The positive tone in your voice really helped my confidence. I took the laptop to the garage with me and used it to make sure I didn't miss anything, which I did anyway. Duh.... EGR valve wasn't connected snugly.

[MrCreed]

This video was super helpful. Took ab 4 hours including plugs and wires while it was apart and having to clean the ports and vally was really the only hard part. Having a lift didn't do me any favors either! Great work guys!

[GATV]

Thank you for this video, it helped me immensely. Worth the effort to not pay big bucks for a mechanic to do it for me!

[hunterhall]

I just did knock sensors on my 2001 2500HD 6.0. This video was super helpful, other than a few minor differences on my truck. My only complaint is you either don’t have the same throttle cable setup or you skipped the part on how to remove them. My truck also has many different sensors and connections, especially around the throttle body. Overall super helpful though

[nathan___]

Whats the name of that tool you used to help remove the fuel line hose ?

[MyLifeThai]

I just finished installing the knock sensors in my 2003 Silverado 2500HD. Thank you so much!

[kentmunz]

Great video! Just changed my sensors yesterday and this video was a tremendous help! Appreciate the step by step and tips. Took about 3 hours for me. Got a couple estimates for $550-650, then came across your video, and so glad I did.
