Thanks, I am looking to add cooling.
So, if the larger cooler does exist for the new diesel and will fit our existing bracket, I will get one of those.

 

Setrab is a good company for oil coolers. However the "leaked picture is not of the diesel. It's an HD f150, 9 row oil cooler for engine block. Anything more than that you are going to need a thermostatic plate and temp gauge. Had this on my 370z with a 25row and it OVERCOOLED during winter time. Oil temps were 140~. Better to have hot oil than cold being that you can't burn off moisture content from crankcase.
