Engine M100.985 6.9
Anyone have information on the tightening torque of:
- the four M6 bolts on the thermostat cover-to-housing?
- the two M12 bolts on the thermostat housing-to-water pump?
Steel bolts and aluminum alloy threads.
Any tips would be welcomed.
You may find info in the Forum Library. I have the M117 service manual . ::)
A good general guide.
Thanks, TNNBenz, I found the tightening torque for the two M12 bolts, with 8.8 grade If I remember correctly = 23 Nm ("Thermostat housing to coolant pump bearing housing") - on page 158 in the "Manual_100-985_Mechanical_04_82.pdf".
Thanks, rumb, great table in general. However, it seems that the torques in the table you forwarded are too high compared to the workshop manual, probably due to the soft aluminum threads?
I couldn't find the torque for the four M6 bolts. Probably around 10 Nm?
