996 C4 Flywheel Bolts

[dlipka]

Hi - Does anyone know how much to torque up these bolts?

Are these bolts different on a 996 TT?

Thanks,

Derek

For C4 it is 25 Nm (19 ftlb.) plus 120 degrees tightening angle.

Yes, a 996TT is different (different engine and flywheel - and 996 is 8 flywheel bolts and 996TT is 9 flywheel bolts).

What do you mean by plus 120 degree tightening angle?

You turn the bolt head an additional 120 degrees. This needs to be a precise angle measurement and is usually accomplished by using an "angle torque gauge" such as this one:
