C5 3.0 HDI Torque Figures

[DHallworth]

Evening all,

I’m in the process of changing the timing belt on the C5.

The belt is changed and tensioned but I’m struggling to find the torque settings for the water pump bolts, the idlers, tensioners, etc. There’s nothing at all about them in the pages from the workshop manual I have.

Does anyone know where I can find the torque settings?

Thanks,
David.

Amazing, thank you very much!

That’s great peace of mind.

If I could be really cheeky, you don’t have the tightening sequence and torque figures for the sump bolts, do you?

Thanks,
David.
