Two ways to do it, one is messy, the other is well, messy.
First method:
Remove filter, drain as much from system as you can. next, disconnect lines from remote filter canister (remember which lines goes to which side of remote canister). Set your adjustable air compressor output to 15-20lbs and insert air hose in to line, insert other line in to bucket, turn on airhose and allow
oil to be pushed out by air pressure. Clean up mess, reattach lines lower lines and fill
oil cooler with fresh
oil until upper line is full, reattach line, fill oil filter, add oil to pan, prime and fire it up.
Second method:
Remove oil cooler from front of car and throw away, replace with new one....
