[C320-list] Coolant leak

[Robert Seastream]

All:

Please see attached pix.  I had to rotate the brass T fitting (below  
my thumb in pix) and associated pipe at its' left so that the sensor  
on the T would clear the (upgraded) alternator casing below it.  I  
rotated it about an eighth turn; the pipe turned also.  This fitting  
is connected to hoses that seem to feed the loop in the hot water  
heater, given the path they take behind the refrigerator.  Now I have  
a slight coolant leak at the end threaded into the engine.  Since I  
rotated the fitting towards the bow, that means I unthreaded the end  
entering the engine by that eighth turn.  Both ends of the fitting  
seem to have been coated with something.  Should I merely try rotating  
the fitting back to its' starting position (if possible-might not  
clear alternator), or need I now remove the fitting and recoat the  
threads?  I don't know what was used.

Bob
