I have another friggin' antifreeze leak from the damn upper water outlet. I am beginning to think it is because of the two dissimilar metals, alum intake and steel water outlet. I would think they heat up and expand and then cool down at different rates. What ever the f#&k the delta heat loss and all that other physics bs I have long since forgotten..lol. Tightened it up a little and I think it stopped. I am damned afraid to get too much torque on those bolts as the aluminum strips very easily :rant BTDT.
