How To Torque Cylinder Head Bolts

http://www.ericthecarguy.com/
Well this was a fun one to make. I believe I covered everything but if you feel I haven't please let me know in the comments below as well as any tips you might have to add as well. I'm not trying to make a big deal about "pound feet" or "foot pounds" I'm just trying to put that out there, the important thing is that you get the proper torque and get the job done right in my opinion, what you decide to call it is up to you.

As always, stay dirty

hi Eric again thanks for the video.... where can i find ALL the torque spec. for my 1997 honda accord if any.

Philippines 1:3

@mrlakayna In a Honda service manual for your vehicle.

Here is a dumb question.....

When torque specs are listed by the bolt size which determines the size of the bolt, the thread diameter or the head size?

I decided to 'do the job right' the other day and torque everything to spec instead of just to what feels right. The bolt head took a 9/16" socket. So I was cranking it up to spec, 75 ft. lb, while thinking "this feels way too tight" and it snapped off. Should it have been spec'd by the thread size instead, which was 3/8" and only 21 ft lb?

[EricTheCarGuy]

@Patrick1776Henry Yea, fastener size is based on thread pitch and the diameter of the fastener itself NOT the head size so keep that in mind. Ex. if the bolt size is 10mm x 1.25, the diameter of the fastener is 10mm, the head size may be 14mm. This is actually an excellent question.

i was wondering, i took out my intake manifold of my gm blazer... the torque specs are 23 ft-ibs to intake manifold, throttle body tbi220 is 18 ft. lbs. can i do this with a 1/2 torque wrench or a 3/8 ? because i found a nice digital torque wrench that is 1/2 it includes ft ibs to nm to in-ibs, i need to ask because since a 1/2 wrench handle is longer than the 3/8 even if i do the same torque specs i may brake the bolts? or doesnt matter as long as i do it right an slowly ? thanks :)

[EricTheCarGuy]

@X2N18 The rule is to try and use the wrench that has the spec you looking to achieve in the MIDDLE of it's range, if it's close to one end or the other of the effective range of the wrench try to find another wrench where the spec is closer to the middle of it's operating range.

Hey Eric, I am rebuilding my Cylinder head for my 95 Honda Civic SOHC Vtech, and I wanted to ask what is the proper way to assemble my Rocker arm, I did the sequencing but not torqued them yet, I noticed that some of my rocker arms that contact the valves some move freely and some of them don't is this normal? or will it fix itself after valve adjustment. Also is this related to the TDC of that particular piston.Have you any videos about this?

Thank you.

You will not find on youtube a better lesson on torque than this. Thanks Eric!

[frias333]

Eric is one of the few that will actually explain everything the way it should be done. Sharing knowledge is always great especially with those who are especially motivated about learning!! Thanks Eric;)

[RickyTippyTappy]

thats the torque specs for a 97 accord with a f22b. i thought that the 6th gen accord with the f23 was to be torqued to 22 ft/lb and then to 90 degrees twice and three times if they are new bolts

[GuyRWood]

Another great vid Eric! I'm 39 and use ft/lbs myself. Weird thing is, I've got a mate who's a real car freak who's in his fifties and he uses NM. Go figure..?

[TripInsure]

You are very good at explaining things. thanks

[A2892Z]

I always torque wheel nuts when possible, to 105NM especially locking nuts. Never do them with a air gun always, a torque wrench.

[cruzin33]

thanks for the tip on storing a torque wrench. I just went and zeroed myn out.

erick your videos are very instructive thanks for taking the time to do these videos i am not a mechanic but i feel like they are very understandable i have a 93 honda a ccord that burns a lot of oil like a quart a day can you tell me what the problem may be also my brother tested the pressure on the cylinders and one of them had a low pressure do you ha ve any videos on that subject thans again
