You shouldn't need to touch the alternator
We need to verify this. Mine says 10Nm
Wikipedia agree with you on the engine, though. I don't know.

I thought you referred to the thermostat housing. What all did you have to remove? You shouldn't have to remove the alternator.
I did refer to the thermostat housing and to get to the thermostat since it's under the Alternator the Alternator needed removed. Am putting a new thermostat in the 2009 Buick Lucerne CXL
Ok. Manual didn't mention removing the alternator.
So 10Nm for the thermostat housing.
Is that the only torque spec you need?
10Nm or simply snug tight.
So just snug tight on two the Thermostat housing bolts?
that's the spec for the 4.6L engine
We need to verify this. Mine says 10Nm
Anyway, I would just tighten it to 10 N-m, and then monitor it. If it seeps .... tighten it some more.
