Default Torque lbs for Water Inlet

I replaced the gasket (between the engine and water inlet) on my water inlet on the engine, however can't find in the AIM what the torque settings should be and am worried about over torquing it.

If you know, please let me know.

Assuming you mean thermostat housing 35 ft/lbs.

Ok, if I replaced the gasket, and torqued to spec, could the housing possibly be bad and need to be replaced?

Depends on what housing, aftermarket some are notorious to not seal. Check the bottom of the housing to see if it's warped. Does it use an o-ring or a gasket, is it pot-metal or aluminum or cast iron? Did you use any type of sealant?

It appears to be aluminum, didn't use any sealant... just the gasket from advanced. when I lay the gasket flat on it, it appears it may be warped slightly.. hopefully replacing that will fix my priblem.

Thanks very much MelWff

use a thin coating of silicone gasket sealer and test the housing for straightness on a flat surface

What matters is what is the material of the part with the threads in it? If the intake manifold if cast iron or steel, 35 ft-lbs. is correct. If the intake manifold is aluminum, the the correct torque is around 23-25 ft-lbs.
