Thanks sixto, I'll see how I feel tomorrow.

What do you make of the block drain plug? It is the one on passenger rear side of the engine that looks like a huge brake caliper bleed screw?
It looks as though its in there real tight. But, when I pulled the head on the 4.5, I went to lift the head out and WOOSH! dumped coolant all over the floor.

Would like a more controlled release this time, but maybe it is better to leave that drain plug alone.
