RE: Heat exchanger oil cooler life expectancy

What kind of heat exchanger do you have? I am not familiar with anything other than mine. Perhaps if you elaborate on what kind of system you have a better answer could be forthcoming

On the cat 3208 that I am working on. The only way for the fluids to mix is the coolant can disperse into the raw water of the exchanger and pump overboard. Raw water cannot enter my cooling /coolant thru the exchanger.

*I am guessing here based on how the system is set up.

*Assuming the pressure on the coolant side is greater than the pump pressure provided by my raw water pump.*I think that it is.

*Can't say for sure as I don't know how much pressure is supplied by my Jabsco pump. Judging by how much water is pumped out the side of my boat it can't be that great.
