Ok, first you need to take the rad fan shroud off, and unplug the temp sensor in the bottom right corner. Then its held on by 2 bolts through brackets on the slam pannel, and the 3 coolant hoses obviously

Also you'll want to take the grill off as there are 2 plastic air guides bolted to the front, which need to be removed before it will come out. 3 of them can be accessed through the grill (just) and one can be accessed from behind on the right side, you'll need a small 13mm ratchet/spanner

Then it just sits in the front crossmemebr, it can be a bit tight but give it a damn good wiggle

Dont forget to transfer the ruber washers from the old one to the bottom lugs, and the temp sender in the bottom right corner.
