Head bolts torque settings

SOURCE: torque settings

1. Tighten the cylinder head bolts sequentially in three steps. NOTE: Perform each step twice. 1st step torque: 39 Nm (4.0 kgf-m, 29 ft. lbs.) 2nd step torque: 69 Nm (7.0 kgf-m, 51 ft. lbs.) 3rd step torque: 98.1 Nm (10.0 kgf-m, 72.3 ft. lbs.) Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the first step.

dear friend-your torque setting is cold 66 nm

Torque all headbolts to 29 ft lbs with a good and accurate torque wrench, then tighten them further in two steps 90 Degrees per step. But if you've replaced the head bolts with new ones tighten them and additional 90 Degrees.

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.
