So after about 4 months of slow coolant loss i finally have a puddle in my driveway!!!! my excitement is due to the fact its not being lost in the engine. Although the timing cover is leaking and my question is should i replace the water pump as well? or just change the gasket on the pump? also anyone know torque specs?

 

If you are going to pull the water pump to fix the leak, you may as well replace the pump. It's cheap insurance against an impending failure.

Torque the pump fasteners 15-22 lb/ft starting at the topmost fastener and working clockwise. (4.6L; 5.4L should be the same; don't know about the 4.2L.)

 

There's coolant coming from your timing chain cover ??? Last time I looked there was oil in there..

 

there is 2 coolant passages they go through the cover to the water pump.
