Thanks

Duffy,
My thoughts: Water will seep easier than coolant 'cause it's viscosity is LESS than coolant. Water just evaporates & doesn't leave a green "CALLING CARD." I always run Bars-Leaks for a week before puttin' in coolant for those unknown seepages that might show up in 80 year old iron. I add 1/2 bottle of Bars-Leaks after draining first water & installing coolant. Bars-Leaks is very safe & won't plug up stuff! (CHIEF said so!) Bill W.
