Rino,
 
Can you provide more temperature = data? Water temps=20 before and after radiator and oil before and after oil cooler if = possible. If=20 you need to move heat to the the water try placing the = exchanger=20 between the radiator out and engine water in. This should increase you = water=20 temps only a few degrees and drop you oil temps. With slightly higher = water=20 temps your radiator should also be more efficient. All my oil is cooled = with an=20 oil to water exchanger and this arrangement has worked best for me. = Yours my be=20 different. I would also place the oil side of the exchanger after = your oil=20 to air exchanger or in parallel. How much additional heat do you = need to=20 more to the water?

I need suggestions on installing an = oil/water heat=20 exchanger.
My oil temp is too high and the water = temp is too=20 low in cruise.
Should I install the exchanger between = the water=20 pump and radiator OR between the radiator out and the = engine?
