Head bolt torque order andft lbs. - Hyundai Motor 2003 Elantra

Hi,



Here is torque steps for cylinder head bolts on your vehicle:



Install the cylinder head and torque the head bolts in numerical order using the following 5-step procedure:

Torque all bolts to 22 ft. lbs. (29 Nm).
Torque all bolts to 58 ft. lbs. (78 Nm).
Loosen all bolts completely.
Torque all bolts to 22 ft. lbs. (29 Nm).
Torque all bolts to 54-61 ft. lbs. (74-83 Nm), or if an angle wrench is used, turn all bolts 80-85 degrees clockwise
Torque sequence:

The site that has that information is called alldata and it is not free.

This is for 201 cubic inch--3.3L engine--engine code R.
1st step 45 ft lbs
2nd step 65 ft lbs
3rd step 65 ft lbs
4th step do not use torque wrench but turn 90 degrees
Bolt torque after 90 degree turn should be over 90 ft lbs, if not replace bolt.

SPECIFICATION LOOKUPS

Cylinder head bolts are usually tightened to around 65 ft-lbs, depending on what the car is.

There's more than 4 cylinder head bolts... There's usually 10 bolts.
There's also a sequence for tightening the bolts:

cylinder head tightening order Google Search

When tightening cylinder head bolts do it in 'stages' and follow the sequence .. ie.. tighten the bolts finger tight first, then torque them up to about 25 ft-lbs. Wait 2 minutes.

Then tighten them to about 45 ft-lbs in sequence. Wait 2 minutes.

Do it again up to about 55 ft-lbs. Wait 2 minutes.

Tighten them up to 65 ft-lbs or whatever is recommended for your car.

Tightening in order/sequence pulls the cylinder head evenly onto the block. Waiting 2 minutes between stages allows a 'stretched' bolt to 'settle'.

I'm not sure what engine you have in your 95 grand am SO I will give you both the 4cyl and 6cyl Specs. Also you didn't ask for the torque sequence. I will include that as well for both. 2.3 DOHC Quad 4cyl: Torque sequence---> front ' 7 3 1 5 9 ' of engine ' 8 6 2 4 10 ' Step 1: torque bolts 1 thru 6 (26 Ft/Lbs & 90 degree turn) Step 2: torque bolts 7 & 8 (15 Ft/Lbs & 90 degree turn) Step 3: torque bolts 9 & 10 (22 Ft/Lbs & 90 degree turn) Recheck final torque in sequence *** CAUTION *** This engine uses "Torque To Yield" (TTY) head bolts that means they permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed in order to obtain proper torque. 3.1 liter V6 Torque sequence--> ' 6 2 3 7 ' ' 5 1 4 8 ' Step 1: torque bolts in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION *** This particular engine uses "Torque To Yield" head bolts(TTY) (that means the bolts permanently stretch during the initial installation.) You MUST use NEW head bolts when replacing or reinstalling the cylinder head in order to obtain the proper torque.

I dont know which engine you have.

420a
1. Torque all center bolts to 25 ft-lbs, torque the 4 corner bolts to 25 ft-lbs
2. Torque all center bolts to 50 ft-lbs, torque the 4 corner bolts to 50 ft-lbs
3. Re-Torque all center bolts to 50 ft-lbs, re-torque the 4 corner bolts to 50 ft-lbs
4. Tighten all bolts in the sequence from #1-#10 an additional 1/4 turn.

7-Bolt 4G63
1. Torque all bolt to 58 ft-lbs in order
2. Loosen all bolts completely to 0 ft-lbs
3. Torque all bolts to 15 ft-lbs in order
4. Tighten all bolt 1/4 turn in order
5. Tighten all bolts an additional 1/4 turn in order.

ARP Head Studs
1. Tighten all bolts to 40 ft-lbs
2. Tighten in steps of 10 ft-lbs increments until the specified torque that you are looking for is reached. This can vary with the amount of boost you plan on running.

Loosen Headbolts in this order:

1 5 4
3 6 2

Tighten Headbolts in this order:

3 1 6
5 2 4

Following the tightening order, torque Head Bolts as following:

1. Torque All to 22 Ft Lbs
2. Torque all to 51 Ft Lbs
3. Loosen all 180 degrees
4. Loosen all 180 degrees
5. Torque Center Two bolts to 25 Ft Lbs
6. Torque Outer 4 bolts to 11 Ft Lbs
7. Tighten all bolts 90 degrees
8. Tighten all bolts 90 degrees again

Make sure you tighten all of them down the first 90* and then go back and tighten them another 90*. Also make sure you put some lube between the bolt and the washer, and put some sealant on the bolt threads. Use GM Thread Sealant.

Here is a picture of the torque procedure.
Bolt #11 threads must be coated with loctite 592 sealant before installation

Tighten all bolts in order to 22 Ft/Lbs.
Tighten all bolts in order to 45 Ft/Lbs
ReTighten all bolts in order to 45 Ft/Lbs
Tighten bolts 1-10 in order to 110 Ft/Lbs
Tighten bolt 11 to 100 Ft/Lbs
Tighten bolts 12-14 to 110 Ft/Lbs

Cylinder Head Tightening Torque and Sequence.

Tighten cylinder head bolts in order shown.
Tightening torque: 36.1 ft. lbs. (49 Nm, 5 kg-m)

Loosen bolts in reverse of order shown.

Retighten cylinder head bolts in order shown.
Tightening torque: 18 ft. lbs. (25 Nm, 2.5 kg-m)

Mark cylinder head bolts for rotational reference.
Rotate cylinder head bolts 90°(1/4 Turn) in order shown.

CAUTION:

• Do not reuse the old cylinder head bolts.

the torque is a 4 step process

1 torque all bolts to 22 ft/lbs
2 torque all bolts to 45 ft/lbs
3 recheck all bolts to 45 ft/lbs
4 torque bolts 1 thru 10 to 110 ft/lbs
bolt 11 to 100 ft/lbs
bolts 12 thru 14 to 110 ft/lbs
bolt #1 is the fourth bolt from the front on the passenger side....#2 is the fourth bolt on the drivers side then you continue in a clockwise order
