It's pretty easy-straight forward type deal. Hassle though in that you have to remove the coolant resivoir- one of the small hoses off the main attatch to it. The other small hose that comes off the main lower hose goes to a pipe that is kinda hidden. One of them feel it but can't see it too well deals.

And of course like most things, I think i spent over an hour the first time replacing it, where I threw the old one on after work, in the dark, in about half an hr.
