My new setup for spring.

Oil cooler is after the filter, but the filter has a bypass on it for when the oil is thick, like cold starts, or when the filter gets clogged.

I would not re-use the cooler. Have you ever cleaned an oil pan with bearing material in it? Even when you can touch it, it can be though to get everything out. If you think you going to get everything out by "flushing it out real good" dream on. Once 10 GPM of oil is pumping through that thing, any little spec you didn't get will work it's way out and into your motor.
