Title: v6 torque figures
Post by: surreymv6 on 04 January 2008, 20:24:09
Hi all
Can anyone help with the Torque settings needed during headgasket change ... ie : cams / covers / manifolds etc, also i  assume they are "stretch" bolts if so what angles  ?

Thanks in advance  .... Adrian

PS. a little pic for you :)

welcome mate :y

what makes you think the head gaskets are gone?

don't know about the torque settings for head bolts but if you have a flick through the maintenance section i'm sure you'll find all you need to know in there.

 I guess that would be because they are laying on my garage floor !  ;D ;D  but really  ... started by changing the HBV / oil cooler & plate but still leaked , after pressure testing could see a "Squirt" from the rear of the n/s head just below ignition module plate, Both heads were then removed (lovely job [smiley=lolk.gif]) i have to admit though i was quite suprised by the amount of "rot" in the gaskets

According to Mr Haynes ... 2.5 & 3.0 are the same ....

Cylinder Head Bolts

Stage 1                   25 Nm
Stage 2                    Angle tighten a further 90 degrees
Stage 3                    Angle tighten a further 90 degrees
Stage 4                    Angle tighten a further 90 degrees
Stage 5                    Angle tighten a further 15 degrees

HTH  :)

VERY IMPORTANT

While they are off check the exhaust gaskets well as this is your best chance to replace them

Yes, as a matter of course fit new multilayer metal exhaust gaskets!
