3.6L GM Engine Torque Specification/Sequence: Cylinder Head Bolts
Вставка
- Опубліковано 1 сер 2020
- Showing you guys how to properly torque down the cylinder head bolts on the 3.6L GM engine. This should apply to Acadia's, Outlook's, Traverse's, and Enclave's with the same 3.6L GM Engines.
First Pass (15mm bolts)- 22 FtLbs Second Pass- 150 Degrees
First Pass (13mm Bolts)- 11 FtLbs Seconf Pass- 75 Degrees - Авто та транспорт
Thanks for putting this up. Greatly appreciated!
Very helpful, thanks ✨🛠️👏🏼
Don't forget to get new bolts as the bolts are designed to stretch!
When you do timing chains how do you determine what location to put the camshafts for top dead center. Is top dead center at stage 2 position or stage 1?
what is the bolt removal sequence?
Will those specs work for a 2013 impala 3.6L dohc flex fuel head cause im having issues with getting the gasket to not leak coolant into the head n mixxing with the oil
What about the Camshaft cap bolts?
I have a 2007 Saturn Aura XR 3.6 is mine the same as this?
What about 3.0 v6 cadillac srx 2010
What should the end foot pounds be near if you don't mind me asking is it below 80 and is there just that 150 degree second faze and that's it it didn't seem very tight for how hard they where to take off
Thanks for watching!
To answer your question properly, I did some research. 150 degrees is equivalant to around 73-80 FtLbs but don't quote me on that. The reasoning behind torqueing down in n is because engineers figured that it would be more consistent when tightening down torque-to-yeild bolts. Which is why you should never reuse headbolts.
Personally, I feel that the reasoning they feel tighter when taking off is because of the pressure these bolts endure during its lifetime and. Also, if you reuse the head bolts and loosen them up after tightening them down,, they won't feel as tight when you first took them off.
Can you verify/confirm, which head bolts, aperently there is a couple that are exposed to the coolant system and should have "sealant" on the threads before torquing?
During the course of me reassembling back together, I did not see any mention of putting sealant on specific bolts that would prevent coolant to leak through. The only other thing that would be used on the threads is Loctite, which is a type of "glue' that would help prevent any bolt from loosening up after assembly.
My 3.6 spun a rod bearing. Just got it back from the shop and I desperately need the torque specs for the rods and mains. Could you please give me them?
I do apologize for my late response.
what.the.total.torque.on.pounds.cylinder.head..not.
Is the push rods hard to change on that engine
there’s no push rods, it’s the DOHC
I ordered head bolts and got threadlock with it. Is that for the smaller bolts?
Could you elaborate more on what you mean by smaller bolts?
@@HP38567 2 smaller bolts in the front
Do the cams have to be removed to get to the head bolts
Yes you do
thanks for this video. Do you have the torque spec for the camshaft caps?
Thank you for watching!
The Torque Spec of the camshaft caps is 89 InLbs!
I was looking for the same thing ty!
Glad it helped!
Hi So that means around 7.5 foot-lb ?
What’s the torque specs on a 12 Arcadia Gmc 3.6 head gasket
The same
Dd you remove the head with engine in the car?
yes you can, there is enough space to pull the heads.
Great Video do they recommend replacing the head bolts
Yes, these bolts are torque-to-yield bolts so they stretch during assembly and need to be replaced when removed. You may reuse them but they may not torque down properly so you may see head gasket failure in the future.
@@HP38567 Thank you
Don't cross thread it bro careful lol.
