It seems the service manuals have been taken down (or at least I can not open them). Can someone please advise me what the torque specs are for the thermostat housing for '10 3.8? I am in the process of trouble shooting a slight over heat problem. I am guessing it is a faulty thermostat (probably sticking halfway thus not allowing full circulation) since if it were the water pump, the car would severely overheat, and the electric fan is running fine.

The manual shows 12.3 to 14.5 ft lbs.
Thank you. What is normal operating temperature? Outside temp 82F running for 15 minutes. My son says the needle has moved up one tick higher than normal. This gauge does not give a temperature reading in numbers. The gauge reads at one tick less than half but he swears it was lower than that at normal operating temps. Everywhere I look in the forums they specify a degree number 200-240.

Opening temperature 82±2°C (179.6±35.6°F)

That's from the manual. Mine also normally reads 1 tick less than half at operating temp.
