Oil Cooler Reinstall

[Tyee II]

When reinstalling the oil cooler on a 7.3 do I need to use sealant on the bolt threads ? Do these go into the oil and coolant passes or are they dead bottomed ? Is there a torque spec for these ? Thanks in advance for your replies.

The diesel supplement manual specifies standard torque for 3/8 and 5/16 coarse threads, IIRC 24 lbs for the front header and 14 lbs for the rear header. I used thread sealant on mine. Didn't figure it would hurt to use the white permatex sealant.

They are blind holes, no need for sealant
