M5 bolt torque on pulley to crank pulley

[Sauerkraut]

for the life of me, I cannot find the specs for the four hex bolts (M5 I think) that hold the one pulley onto the crank pulley, the one that needs to be removed to expose the crank pulley bolt.

can anyone help? the engine is a 1.9 TD AAZ

**EDIT**

Sorry for being a rookie, I guess that is the Harmonic Balancer that should be torqued to 18 ftlb.
