Friend of mine has twin crusaders. One is operating normally. During a multi day cruise
, the other engine
ran fine for the first three days then overheated at the start of the fourth day. He immediately shut it off and checked it over. He discovered the coolant
reservoir was empty so he refilled it. And refilled it. And refilled it. After it took a lot of coolant
, it was fine the entire day. The next day, the same thing happened. There are no obvious signs of leakage in the bilge
so we’re theorizing the leak is in an exchanger and the coolant is being ejected with the exhaust
. We thought about throwing some dye in the coolant to see if it shows up in the discharge. Any other ideas or diagnostic approaches?
