Needless to say, this is a serious PITA, especially since mine looked like it was chewed by a rodent. I would also suggest you replace everything you take off that's run with the serpentine belt, i.e., alternator and water pump. You don't want to have to go back in there in a couple of months.

Yes, it's always good to replace parts while you're in there for this job. We have some water pump super kits that are perfect to add onto this project list. can check them out here: Mini Cooper & Cooper S (R50/R52/R53) - Water Pump, Thermostat & Hoses - Page 1
