Nm for studs > exhaust manifold

[Rinus]

Hello,

 

before I will mount cast-manifold,

I will place some fresh exhaust manifold studs (bolts?)

 

Does anyone know how many Nm these need,

so I will not screw up the head

 

thanks

Hello

 

This is from the workshop manual for the US spec car, it's very useful.

If you're asking how tight are the studs wound in, then hand tight until they bottom out.

 

The nuts that are used on the studs to hold the manifold on are as posted above.

Many thanks guys, usefull info!!

 

@ Tlicence;

Thats what I meant, how thight they shoud wound in, so hand tight will be ok...

 

Next problem would have beenbe how many nm's the nuts should have ,

so 39-40Nm will go for that,

 

thanks!
