Well put together. Short and concise, but not lacking the important info. Just what us DIY guys need!

[@MattsShop]

Thanks man, I try my best!

[@DanMestayer]

Everything I wish I knew in one video. I fought this over and over until I watched many videos. Good info. Only thing I'd add, my fluid intrusion came from a failing seal for the plastic heater core connectors.

[@MattsShop]

Thanks man. I tried to put it all in one video.

[@JesusRodriguez-nx8zi]

I had check engine for both sensors. Changed them out, new harness. cleaned the area, changed intake gasket, and code came back that same day. Drives normal, CEL turns off and on itself 🤷

[@MattsShop]

That's bizarre. I've heard this happening to some guys, and they can't figure out why. I'd check the ohms at the plug with the multimeter. That will tell you if they are reading right.

[@JesusRodriguez-nx8zi]

@@MattsShopI just tested mine with key on and both sensors read 107k ohms, anything else you think it may be! Great video btw

[@devilshockey2142]

Literally same issue with my 6.0

[@JesusRodriguez-nx8zi]

@@devilshockey2142 let me know when you fix it lol

[@TR-qr9hs]

​@@MattsShopcan u drive 3 hours with the bad knock sensor.

[@SMTMainline]

Have you considered doing a video on how to time V6 outboards using the Joe Reeves method of timing?

[@MattsShop]

I tried the Joe Reeves timing method before. I didn't like the results. I time the Evinrudes the way the manual says and then set WOT timing on the water. Dangerous, but it gives the best results.

[@SMTMainline]

@@MattsShopWhat did you dislike about the results? I know some mechanics who swear by it but I’ve never tried it myself

[@dustinryan9671]

I have a 2005 Suburban and have went through hell with knock sensors. Getting ready to replace them for the fourth time. I can't get the engine light from not coming back. Even tested the line from the knock sensor wiring to the computer and it had great connection. Going to give it ago again if I it does not work it's going to the shop I am done with it.

[@MattsShop]

Use Delphi sensors from a reliable source and make sure they read 99k-100k ohms, especially once wired up.

[@dustinryan9671]

@@MattsShop I just picked up Delphi from Autozone. I had to pay twice as much as the ones on Rockauto but if I have to take them back I wont have to wait a week. Thanks for the channel enjoy the content.

Love it

Thanks man

Hello from România!i want to see if is posibile to see how mounting water pump for Yanmar IM 2210 b.thank you very much!

[@Klassiccycles]

Can you explain the "dam" you use to seal up the sensor?

[@MattsShop]

High temp silicone to stop water from running or pooling up in the sensor cavity.

[@jasonrocha2653]

Just did mine.

[@MattsShop]

Awesome 👌

[@Socal-1776]

I’m can’t get rid of this issue took it to a mechanic I bought the sensors and harness from the dealer ohm them @99 and harness was good also code came back mechanic changed them out again with Delphi and it came back again. I took it back and he said an engine knock must be triggering it . I reset code and drove 60 miles then it came back on cleaned and test pcm checked wires from pcm to ks and it all checked out good. Truck runs good only has 133k on the 4.8 can’t figure it out and it’s ticking me off any ideas would be appreciated

[@MattsShop]

On trucks like this I'm guessing it has high miles? I'd test the ohms at the PCM connector. If it was me I might try to relocate them to the sides of the heads where the knock can't really be detected. It's probably possible to bypass them with some sort of resistor. Although that would be an experiment. Maybe think differently and try to figure out why it is knocking and fix that.

[@Socal-1776]

@@MattsShop I never hear a knock I think mechanic just gave up after changing it 2wice. lol I ordered a fancy obd that should tell me what sensors are doing . If all else fails I may relocate and cross my fingers

[@541-RAIDER]

143k miles, that pickup is barely broken in!

[@MattsShop]

I know right!

[@jahremejoefield334]

How u didn’t replace the valley pan seal while u was there

[@MattsShop]

Wasn't leaking so I left it alone.

[@vejaigajai9110]

Found u on tic tok

[@MattsShop]

Hey what's up?

[@anthonylawrencesnow]

Just tested mine and I am at 100.2 and 100.5. Do you think this is far enough out of spec to replace?

[@MattsShop]

No, look up the spec range those look like they are in range.

[@RaulAdams-ki2pr]

I hear OEM ACdelcp are not good...Any brand recommendations?

[@steveslate3601]

I used Delphi many years ago with great success. I wouldn't use anything else

[@RaulAdams-ki2pr]

@@steveslate3601 Thank you,

[@MattsShop]

I only use Delphi sensors on these trucks.

[@steveslate3601]

@@MattsShop hey Matt, I enjoy your videos. Any ideas about a po 401 on my 00 silverado? I can't find an AC Delco egr valve that fits just a Delphi. I've also cleaned passages. Hopefully you can help!!

[@JorgeOrtega-du3im]

Mine is all rusted and stuck and can get it out

[@MattsShop]

That's tough. Sometimes they break off. I'd fill the cup with PB Blaster if it was me.

[@donhacker7384]

No disrespect,, but pressure washing!!! Unbelievable. You NEVER pressure wash a engine..

[@MattsShop]

I know right, these engines should never be pressure washed. The water just sits in the knock sensor cups of the engine.

[@toomanytododge2594]

Oh chevy things I have dodges and no issues with pressure washing under the hood. Sorry just not a chevy guy anymore have an 07 classic. Beautiful shape but the interior is brittle and the lifters wiped out the cam so we switched to dodges. And they just run forever
