Torque specs for opel corsa 1.4 comfort utility 2005 model


Assume you are needing the cylinder head torque specs?

The head bolts are angular torqued and best practice is to fit new bolts and ensure all the female threads are thoroughly cleaned. I recommend greasing the bolt threads and washer faces.

The initial torque (following a spiral pattern) is 25 NM followed by angular movements of (degrees) 90 + 90 + 90 + 45
I generally start the engine and thoroughly warm up and allow it to cool before the final 45.

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.
