This is one of the best instructional videos I have ever seen. Being a retired GM mechanic I am completely impressed with your video. Great job guys. Great job.

I just completed mine with the help of your video, great job. I have a couple friends that worked at Chevy. They made a good point to make sure where the head bolts go into are COMPLETELY dry. If not, any water, coolant in the holes will expand and crack the block. They have seen it plenty of times. I would of never even thought of that. Use lots of air and make sure they are DRY.

Why can’t every instructional video be this good!! Thank you guys! Simple and to the point. Perfect

It was about 9 minutes into it that I realized exactly how lazy I've become and that I would just rather sell my truck 😂

Great video. Helped out this weekend. From tear down to start up was about 12hours. I don’t have power tools so everything was by hand but this was definitely an easier repair than what I was expecting. Took lots of pics for when I had to put everything back. Thank you for taking the time to do this video. Saved me a lot of money and having to miss work.

This was likely the single best how-to video I've ever seen. It's definitely worth the watch.

Seriously this is the perfect instruction video. No bs, straight to the point. The world would be a better place with more people like you guys. Lol

Went to 4 different web sites on torque spec and got 4 different answers. Thanks for the video!

Thanks for this video. I know it’s 3 yrs ago but still very helpful. For those of you doing this job, you may as well change the oil pressure sensor while you have the intake off, even if you don’t need one. It WILL leak or fail eventually. Thanks again!

Excellent video. The only part that seems unrealistic is the complete absence of obscenities. 😄

Best instructional video on head gasket replacement ever made. 👌. Thank you so much you guys. Both of you are amazing!!

Perfect. I’m used to doing my own work and rather than send to a professional who will take shortcuts and eventually fail prematurely. I will do it myself and only blame myself if anything happens. It’s a great time to freshen the heads, add heavier duty springs, rocker, maybe a set of headers. Thank you for a great video

Reviewing your video for head gasket process, I notice something that might help you which I learned when I did intake manifold gaskets a few years ago. When the wiring harness is hanging in the way of the intake - I used bungee cords to pull it out of the way and it worked great. It was hovering above the engine and I had plenty of clearance for the manifold.

This is an excellent video! Extremely easy to follow along. I am getting wiffs of coolant on my 03 pickup I purchased a week ago. I feel this is in my future, stopped by to see the “ease” of this. Your video gives me great confidence in doing a head job now. THANK YOU

Huge help. I have a 2006 Silverado with a 4.8 and the 706 heads. Replaced the head gaskets at 200,000 miles but they didn’t shave the heads and they are no warped and need replaced at 240,000. Got them off rockauto for a heck of a deal. Thanks for the help and step by step info!

Looks a bit intimidating but I like cm taking into a challenge and thanks to you guys I think I can pull this off. Great video. Thanks!

Thank you for the video. I got mine apart in 3 hours but I have a broken collarbone and a couple ribs 🤕

This gave me motivation thank u guys

I love how you don’t have to mess with the timing chain on over head valve engines

That’s probbaly the best trick I’ve seen with the extension with the hammer for the clutch fan

Awesome job. Really appreciate it. Well laid out this is the next step on my suburban. Be blessed guys. Richard Iowa.

I got a 03 Yukon with the 5.3. I was thinking today that I would take it to a shop to have new gaskets installed + oil/coolant changes. After watching this video I honestly think I could pull this off on my own as long as 1) I am patient (I tend to ruin stuff when I rush) 2) Good weather (I'll be in my driveway) And 3) I have the proper tools (I'll need a torque wrench and that fuel line tool)

Simple and to the point no extra BS thank you

Amazing video. You're a great instructor. Gonna attempt this soon when I get the time

Update*** Again, Thanks for making this video, it really helped me out! This video helped me out a lot but I had 1/64 the luck you had. Thanks for making this video. Took about 15 hours. I snapped the heads off all the exhaust bolts, had to sawzall 1 of 3 exhaust bolts to get the passenger exhaust manifold off(no possible to get the driver side manifold off, dip stick housing thing came right off after I unbolted it from the head (still dont know how I'm getting that out), my coolant cross over ( which went under the intake manifold and to the back of the motor) crumbled to pieces, the knock sensors turned to dust. I have a 2000 Silverado 1500 5.3l 150,850 miles. Got the motor cleaned up and all back together, runs great. I used enginetech remanufactured 862 heads, new head bolts, miele multilayer steel head gasket, updated throttle body gaskets and replaced a lot of other parts

What works for me is to tie a strap on the exhaust manifold to the wheel it will separate from the engine & you'll be able to remove the head 😁😀

One thing I’m going to add is mark your pushrods they HAVE TO GO BACK in the same place especially if you have some miles on the rig they all will have wear patterns and it would be very beneficial they go back right where they came from

Brother you saved me on this video!! Thank you! Next project!!!

Man thank you so much I dint know how to take off everything and put back to place a freez plug tutorial next 😅

My twin brother has this truck, he says that the instructional video is amazing but the music doesn’t make the work any less intimidating.

Replace those knock sensors while you're at it.

Nicely done. Thank you.

You guys made it look easy great work 👍

This was an amazing video, I have a 2005 Chevy avalanche that needs this type of work unfortunately I'm not that mechanically inclined, changing oil changing batteries spark plugs filters those things I can do but it seems these boys are top-notch 👍🏾, I think my best bet is just to buy another engine 🤣🤣🤣, and swallow the bullet on the labor cost 😲

I've always made good time on these jobs but damn! You guys are fast! Nice video

Very good video, going to do it on my truck. Have done all the maintenance on it. Should be straightforward, thank you guys for this great video 💯

Had a 2005 aka 2004 built Silverado, till the head gasket blew on me April Fools Day!~ Only 167,000 Miles, but got it with 57K miles in 2007 from my brother. Caused the power steering & braking system to fail at the same time, happened while driving and ended up in a cemetery easement.

Thanks. This will help me a lot.I'm just wondering about intake gasket.you guys didn't mention it.

Such a good video. 3rd time using it now lol! Great job guys, thanks!!

Do yourself a favor and take lots of pics. It makes reassembly much easier. Great vid guys.

Should have done the lifters while you had the heads off. I'm amazed none of those exhaust manifold bolts broke.

I got my head gaskets and everything replaced and that all worked out great but you forgot to mention that the rockers need special adjusting when you put them back in and I didn’t do that and now my rockers sound like shit

this was great, however there was only one really big issue that I came across. The Buick Rainier/Chevy Trail blazer have this same engine. The compartment is much smaller and working around the exhaust manifold is a huge pain. A huge exercise in patience.

About to start mine on my 2000 suburban its misfiring barely running but loses water out tailpipe so about to put two new heads on and see how she runs afterwards.

Love the happy toddler music. Surprised u guys aren’t making glitter slime

Awesome video… my only reason to look at a additional video is because I wouldn’t know about securing the rocker arms correctly. 🥴

Very good video, want to do my sierra , butblooks a lil intimidating.

Great job explaining. I think I am going to have to do this soon. I am slowly losing coolant and I think my truck has the Castec 706 faulty heads. Going to have to replace both heads. Just curious how many miles on the truck. Thx

Wow I replace head gaste in a Camry that was a job this LS engine is super easy maybe the only problem is you have broken bolts in the exhaust manifolds. But you guys did and awesome job in the truck and the video. Thank you very much but I don’t see any beer through the whole process 😂😂

Soo what did you do to clean up the old gasket material on the block

Great video, only thing I would suggest is to get rid of the background music that was playing.

It’s a good idea to replace the oil pressure sending unit & filter while the intake is off.

Love the video, hate the music. Thanks brother! 👍🏻🇺🇸

Awesome video 🤝🏾

I was looking to see how you guys address the coolant on the head bolts holes, also how to do the valve lash.

so none of the head bolts broke???? dayum!! great vid yall, thanks!

Thanks brother for this video Haves help me a lot keep it up bro Ur the

Great job very well explained 👍

My only complaint is the following since you had the heads off already. It would’ve been a good time to change the lifters even though nothing was wrong with them. It would’ve been cheaper to just get that out-of-the-way and change them because they are notorious for lifter problems. And second, you should’ve just changed the push rods as well, even though they look good they don’t cost that much but other than that, it was good video

What do you torque the rocker arm bolts to?

In need of replacing my head gaskets this video was very helpful thank you brother

awesome video! but wow this looks very intimidating. might be above my skill set lol

Excellent video thank you so much!

How much do you torque down the rocker arm bolts to?

How much did u guys charge for the head gasket job?

Did you have to rotate the crankshaft and if you torqued the rocker arm bolts what torque was set?

How tight for the rocker arms noo you never saided 😢

replace that oil pressure sensor while its easy

Do you need a tune up after installing new cylinders heads? Even if they have the same AFR , would you still need a tune since it’s a new cylinder head with a different compression rate or , you can just swap the cylinder head an it be perfectly fine?

Jeez. Had no idea you had to remove so much for a head gasket… I might as well do cam, lifters/springs, and headers while I have it all apart.

That sun moved awfully far for 1hr 45 min.😂

just wanted to thank you for great video and instructions thumbs up

Im just gonna say a prayer and hope a tree falls on my truck in the morning…

I'm working on my 08' 5.3 suburban with DOD... I took off all the spark plugs from the driver side and they were all wet with oil. And there is oil leaking on the front driver side of the head between the block and the head where cylinder #1 is at. And my oil pressure was at 20psi and lower while i was running it

When you put rocker arms in did ya torque them ? If so how much and do ya have to rotate the cam or just torque em all down

nice about to do this to my truck, this is going to help a lot, Thanks!!

Looks pretty easy but for a normal person I think is really hard...

what ft/lbs did you tighten the rocker arm bolts to? is there any valve lash adjustment?

when placing the valves back on did you have to reset the gap?

Great video I was gonna do it myself now just gonna get a mechanic lol 😆 😅

When u toqure the rockers what is the spec on them

Excellent video thanks for sharing!

Very detailed amazing job

Great vid !! BTW what caused the blown head gasket ?

awesome to the point video. noty a bunch of needles story telling.

Great Video, Thanks

EXCELLENT VIDEO GUYS ! THANK YOU !!!!!

Anything else yall reccomend replacing "while you are there?" I'm thinking knock sensors and harness. Anything else?

very good informational video

That radiator is supposed to have a plastic drain plug on the bottom driver side of the radiator.

Great video guys 👍

Can coolant leak from the head gaskets on these Chevy trucks?

Awesome job guys .!! Bravo.How did you guys clean the heads to make them looks that clean ?

Excellent work 🍻

So when did we talk about the intake gaskets? Thanks for the video!

Hey guys great job! One question tho. Do you guys do anything with timing ( top of center) like other engines?

I get this was done a long time ago, but if you guys are still around, I did this job got everything back together, I started the engine but it immediately stalled. Did some research, and found a number of things it could be, but what would you guys think is a possible issue?

Do you have to turn the cam when you torque the rocker arms?

Great video

Did you also replace the intake gaskets?
