Hi Jon,
I am sure others would confirm that you probably should take steps to
isloate the leak, like pressure testing for example.
About 3 months ago I was driving along on the freeway and the overtemp
buzzer went off, and the temp gauge was glued to the top. Of course
immediately pulled off, let it cool down, and added water to see if I could
understand more about the problem. It came out as fast as I put it in.
The problem was the plastic distribution unit, it had a large hole in it,
like a whole section of the thing just blew off somehow. I replaced it with
the GoWesty stainless steel version, costs about $10 more than the stock
plastic part and well worth it. So you might want to consider this if you
are disconecting things in this area. The GoWesty part description suggests
that the distribution unit is a failure prone part.
Here it is: http://www.gowesty.com/ec_view_details.php?id=4328
Pretty straight forward to replace, had to remove the air box, and then just
some clamps from both below and from inside the engine compartment.
