Thanks for the tips, got it done last nite, letting the silicone set up today, and will refill the coolant tonite after work. Kewlynx, the FSM doesnt list a torque spec, but my Clymer manual does (8-11 ft/lbs). I am curious why the recomendation for sealer on the bolt threads, it does not appear any are actually in water passages, though they are near.
