While the engine cooler is not a component that goes bad often, it should always be replaced after a catastrophic failure. If metal has been pushed through your engine, it can accumulate in the oil cooler. Since these oil coolers have a stack plate design, it is nearly impossible to clean out any metal debris.
An easy way to test the oil cooler is to remove the oil filter and pressure test the cooling system. Any air escaping from the area on the area where the oil filter screws on is an indication of it leaking internally. This should be replaced.
