I am not really a fan of cleaning oil coolers; for what they cost I prefer to change them - in the process of cleaning them it is often possible to loosen sludge and debris that then comes free after you refit the cooler, it can then find its way into somewhere you don't want it - like an oil gallery to a main bearing.  It is possible to have them ultrasonically cleaned; which does a more thorough job, but I've still known people to have problems afterwards.
