SOURCE: tightening head

New Headbolts are recommended

Long bolts are torqued to 46'lbs + 90 degrees.

Short bolts are torqued 43'lbs + 90 degrees.

Start in the center, and work to the edges, torquing the bolts in two stages.

Rockers are torqued to 22'lbs.

SOURCE: serpentine belt tensioner will not tighten

If the tensioner will not keep the belt tight then the tensioner is bad and will need to be replaced. The spring on the inside will loose it's tension over time.

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

SOURCE: head bolt tension setting

these specs straight from service info
single cam
25Nm + 70deg+ 70deg+ 30deg
twin cam
25Nm+70deg+70deg+ 30deg

alot of after market gasket sets are the 25Nm and 3 lots of 60deg and the extra 10deg bolts are meant to be replaced (use once only) alot of bolts tend to start stretching when doing last 10 deg use oil on threads and washers under bolts 25 and 3 lots of 60deg is correct and more commonly used.

Head tensions, daewoo lanos, 2002 1.5 litre, what are they without the degrees?


I just googled it and it would seem the bolts should be greased and tightened initially, in the correct sequence, to 34 lb-ft and then tightened a further 90 degrees.

Initial torque and degrees is all you get on engines originally built by robots...

Hi do i need to replace the main bearing and the conrod bearing bolts on the opel corsa 6W engine 2006 model


it is good mechanical practice to replace all bolts that are operating under tension. That includes con rod bolts , big end bolts fly wheel bolts , head studs and crank shaft bolt. Some manuals recommend the replacement of cam shaft sprocket bolts as well. This practice is recommended where the engine is driven at high rpms. It is recommended practice because the tension effect actually twists the bolt and this combined with the tensional stress makes the bolts prone to failure. As it adds considerably to the cost many mechanics do not follow the practice but will charge for the new bolts as well.

Torque on head bolts 3.0


This must be done in a specific sequence In THE ORDER described. It is important to know that Ford used a torque to yield tightening process. This effectively stretches the bolt to keep it tensioned. So removing these bolts means you have to throw them away...they cannot be re-used. ALWAYS use new bolts.

Follow the sequence shown in the diagram below and perform these 5 steps EXACTLY (yes, you do two quarter turns at the end):

1. Tighten all bolts to 37 lbs-ft

2. Loosen the bolts one full turn

3. Now torque all bolts to 22 lbs-ft

4. Tighten all bolts an additional 1/4 turn (90 degrees)

5. Tighten all bolts another 1/4 turn (90 degrees)

Hi i'm eduardo and i have a '94 nissan pathfinder 4wd...engine 3.0.... i want to know the head torque specifications .


Hi Eduardo:
Check this information (click over pics for zoom)...

zjlimited_1062.jpg

Fig. 20: Exploded view of the cylinder head assembly-VG30E engine


zjlimited_1063.jpg

Fig. 15: Cylinder head loosening sequence-VG30i and VG30E engines


zjlimited_1064.jpg

Fig. 17: Cylinder head torque sequence-VG30i and VG30E engines


Install the cylinder head with a new gasket. Apply clean engine oil to the bolt threads and seats, then install the bolts with washers (beveled edges up) in the correct position. Note that bolts 4, 5, 12 and 13 measure 5.00 in. (127mm), and are longer than the others. The other bolts are 4.17 in. (106mm) long.

Tighten the bolts in the proper sequence, in the following stages:
Tighten all bolts, in order, to 22 ft. lbs. (29 Nm).
Tighten all bolts, in order, to 43 ft. lbs. (59 Nm).
Loosen all bolts completely.
Tighten all bolts, in order, to 22 ft. lbs. (29 Nm).
Tighten all bolts, in order, to 40-47 ft. lbs. (54-64 Nm). Or, if you have an angle torque wrench available, tighten them an additional 60-65 degrees.


Hope this helps; remember to rate this answer. Good luck.

I have a 1998 Holden Astra eng noEL20B24119 and want to know the Head bolt torque settings and sequence. The engine is the transition model with twin tappet cover seals. has the torx star headed bolts.


I cannot find a EL20B in my data,but all Astra listed had the same head sequence as shown:

10 6 2 3 7

9 5 1 4 8

the torque specs for the C20XE,C20NE,X20XEV were all
25nm(18lb/ft),-then 90 deg,-90deg,-90deg.
Z20LET were as above plus an additional 15deg.
Same data for smaller and larger engines(except a couple that were 45deg instead of 15)
Make sure that you replace the head bolts with new,they are torque to yield bolts that are designed to stretch to 'plastic' state,and should not be reused.
Put grease(graphite if you have it) under bolt heads and washers,oil the threads.
Usually the head sets come with the torque specs.
I hope this helps you.
