Could not find the specs for this but it should not be very tight. Sludge could be locking up the threads and it is best to manually turn it slowly, backing off and turning to get it loose.
If you are removing the oil cooler, I believe it is not necessary to remove this. At side of oil cooler there are a few 10mm hex bolts holding the cooler housing.
