Depends on where in the circuit the cooler is relative to the filter. If
the cooler is before the filter, than it will tend to accumulate crud.
Even so, since some crud is small enough to pass through the filter (that's
why oil turns black) a used oil cooler can be pretty arteriosclerotic.

fact, I'd scrap most any cooler of unknown parentage. Who knows what sort

little bits just waiting to dislodge into your motor!
