Did you clean the old gaskets off when the water pump was replaced?
Yes, but sometimes some of the old gasket is still stuck on the engine and if you did not clean the old gasket off it would leak there.
the old gaskets were already completely gone..dude that had the truck before me didnt do any up keep
There is a torque spec for them but if they are tight they rarely leak. (I do not use a torque wrench on them)
30 ft lbs is the torque spec
