Can someone please let me know if the oil and/or the coolant are required to be drained inorder to replace the two o-rings in the oil cooler? Thank you very much.

The coolant pipes can be left attached, but I think you need to drain the oil otherwise you'll have a mess... I need to do this, along with change both coolant hoses on the oil cooler on a 2000 S80 T6.
