As you know there is a specific torque specs and sequence to install the cylinder head. The concept apply to removing the cylinder head as well. Most people will remove the bolts but NOT in a specific sequence as a result they may make cylinder head uneven. In this video we explain what you need to know about removing the cylinder head.

at the beginning of the video when head revving i expected that '' beautiful voice of scotty cillmer.
Thank you for sharing this video, I hope this prevents more people from unknowingly warping their cylinder head(s). I have always removed/installed in this way.
Save yourself the watch. His advice is to not zap the bolts off, but to reverse the tightening sequence in steps. This can reduce stress and potential deflection of the head/block. 0:05
@4:00 you actually tighten the bolt 😁 (you're supposed to go counterclockwise) Another thing, the sequence is diagonal on some engines so the pattern (on your pad swap 3-4 and 7-8 to get a diagonal pattern) you show may not be the correct one for some engines, always check the repair handbook on the specific vehicle/engine is my recommendation.
I’m always super cautious, I go with and 1/8 of turn, another 1/8, another 1/8 etc....takes forever 😁
An easy way to remove a stubborn cylinder head--after all the bolts are undone, find which piston(s) are closest to TDC, and release their rocker arms so that all valves in that cylinder are closed on their seats. Pull the spark plug, and pump pressurized air from an air compressor or bicycle tire pump. Often the head will pop loose.
Excellent advise . Quarter turn then half turn opening sequence. 90' and 180' degrees.
Head bolts loosen anti-clockwise. Bolts tighten in a clockwise direction take care 4:28
This process sounds very reasonable. Does the head still need to be milled flat? How about the reassembly torque process?
Pretty hard to tell if the bolt slackening sequence has much to do with it. Most of the time, if a head is being removed it's because there's been an engine failure of some sort, or the head gasket has failed. Usually because of overheating, in which case the head will be warped anyway 9 times out of 10.
48 seconds in, I thought the same as you I stop the video and I read the comments LOL.
It's where the best info is
I'm actually glad I came across this video, because I'm removing my 4 cylinder head to hopefully get a small crack welded and I didn't know the removal process
And that's why I do my own work and never let anyone touch my car.
Let's ignore the correct removal procedure, and risk damaging the heads, because I'd you're doing so something has probably gone wrong anyways. Incredibly lazy. Wow.
@@PJ-qx5yt Why else would you be pulling the head off? I'm afraid you're showing your ignorance here buddy. The fact is that if you are removing the head because you suspect there is a problem causing issues with the coolant system, then the head would not be going back on without being skimmed first anyway! In which case it absolutely does not matter how it is removed! See the logic now?🙄
Have a 2011 4 cylinder Journey. Tried to do a plug change on it.
The # 2 cylinder plug will turn but will not come out. Maybe it was put in cross treaded by the prior owner I don't know. What might be the problem causing this. How would one go about changing the head what kind of a process would that be ?
GOOD INFO !!!! All you mechanics out there i think you should do it this way.
Thankful you for the lesson,👍👍
I’m glad I watched this. I’m removing my first head tomorrow
really important video and easy to understand.
Very interesting. I never knew you had to remove the head bolts in a certain sequence.
Neither did I..... and I took one off last night...........
Great video thanks for your helpful advice
Good stuff. Rather be safe than sorry.
Thank you for this informative video.
Thank you for sharing
Omg thank you!!!
Hi I have a 2012 Mitsubishi 2.5 Barbarian DID do you have a video showing how to change the head gasket. Great Videos you have helped me many times hope you can help with this one. Many thanks keep up the good work Jon
Cool thank you.
Great video. Thanks for the info.
I wish I seen this before trying to remove mine.
Interesting.... Tq
And when you assemble it back you need to do it exactly in the reverse order, from center towards the outside.
I remember this on my VW aircooled engines.
Thank you for this video this is what I needed
I learnt sumthin! Tky❤
Very helpful! Thanks!
Thanks bro very useful
I'll skip the disagreement and just move on to the clear mistake in this video. In every sequence example, using your breaker bar, you showed a motion. Just pointing that one out.
Good man ❤
9 out of 10 ? Really I don't know a single mechanic who takes them off wrong, it must be an issue with people you know
Guys thanks. guys good video guys. helped alot guys. Guys
Very helpful ! Great video more tips pls
Thanks for the advice bro🇬🇧👍
How come most of ur videos u don't show any type of tutorial. I'm a visual learner
very good info thanks
Thank you!
it says this in the service manual for every car. anyone working on a car who can't be bothered to crack open the service manual shouldn't be working on that car in my opinion.
Some cars are bought second hand and service manual s are hard to find. Especially for old cars like the 1967 Toyota.....
Great info thanks🤠👍
Thought the thumbnail was a dog repairing the engine and i was like yeah obviously not a good idea but a good boy
thanks great video,what for a nissan frontier k24de. thanks again
i have a 2.4l 07 chevy colbalt ss and the head is stuck it wont come off all bolts have been properly removed any ideas?
I had a similiar case with an old 3 cyl engine. It was seized and the head would not come off. I filled up the cylinders with diesel fuel and left it for a couple of days. Then I went to town on it with a hammer and it was off. No damage whatsoever!
Genius
Does this apply to any car? I have a 4 cyl. rio kia.
I just used my impact gun and I started to left and moved to the right. Very fast.
This is basic stuff i learned in auto shop in high school and cat also drills this into your head in there classes. Only weekend guys would do this unless they don't have a manual, most parts comes with instructions. I think only gave men do that on blown engines...lol
Any cave man can do this..
I carefully read the manual text and understood to loosen bolts with the obviously opposite procedure to tightening.
I then proceeded to use the handy additional diagram working happily and carefully in logical numerical order meticulously loosening each bolt to the tightening pattern sequence… 💩
If you’re replacing the gasket with a new one why does it matter how you remove them.. when I stalling it’s important
Yeah better do it right or u will be redoing it again like me lmao , n dont fix ur cars 420ed out or this will happen to u also
lol true, just reminded me to
How many times he say ok?
Iv always done this the same way normal make sure you torque rgt
Why don't it say this in the service manual you would think they would mention this only has the sequence
Right....in my car manual it says to turn each one 1/4 a turn until you can take them out by hand. The most important step is says is to reinstall the bolts in there exact location that they came out of which he clearly didn't mention lol.
@@LoneWolf-ze2ht that's because most cars don't reuse the old head bolts, since they stretch. You have to buy and use brand new ones when reinstalling
If your a DIY ER AND dont have a basic haynes manual, chilton manual, all data, motor manual, Prodemand which you can get free at your local library that will explain all of that and the specs and much more so your wrong most people who know how to read know this
You are showing us how to remove the bolts but you demonstrate the 90° and 180° in clockwise direction, most Important here is another important thing, right tightly, lefty loose 😅
What about putting it back on
Reverse
Your link for your facebook page in desc. is broken
You are not uncrushing the head gasket.
9 out of 10? Everyone I know checks torque specs as it’s one of the most basic steps…if you don’t know that; best stick to Lego until someone can show you.
thx is he talking underwater??
Is there a good reason why most of the auto repair videos that I click on are with some Russian dude I can't fully understand?
Oh Ricky Booby I am a french formula un driver
The click bait has gotten ridiculous on here. This is like 15 videos titled "remove head" and literally not 1 has removed a head
It is because you can't read properly the title...
Yo this mf spittin facts
You're wasting time I'm a machanic it's simple.
Over hyped bullshit really. Ive changed a hundred cyl heads and never had a problem. No need to follow any pattern for losen.
A fucking hate the loud as beginning.
Thank you so fucking much
You just saved me like alot of bs and money
Don't ever ever try to Remove the cylinder head unless you have to ,,,crack head or head gasket only ,,, the sell head gasket liquid gel ceramic liquid repair the only thing is they last 1 year 5 months ,, may last 2 years n 6 months by changing coolant to pink for aluminum , oil must be half n half thinner n thicker than regular old high mileage plus a additive called bestline , adding a small electric fan on hood with hood scoop, also using a larger thicker radiator, n . What this does keeps cool the liquid gel ceramic formula ,specially in hot summer heat storm rough n long drives overhauls ,. A head can be rebuild without removal with proper tools n directions, less time than removal,
I will defeat you RICKI BOBBY! lol....Is this the guy from Taledega nights?
Looks like him, could be his twin brother....
