coolant in raw water system

[michael tero]

hey guys i've got an isuzu 260 h.p model # a-6bg1t engine . i'm getting coolant into the raw water strainer /intake. any help sending me in the right direction for finding the leak would be greatly appreciated ! i've got a call into a diesel mechanic but will continue to try to run this down myself as well . thanks much.

How was it winterized? If the exhaust elbow is "freshwater" cooled it may be cracked and bleeding back.Put a pressure tester on the expansion tank and put a little (10psi) pressure in it and see if it holds overnight.

crack in the heat exchanger.

had the heat exchanger pressure tested, now just to find out what it's gonna cost.
