1)	Assemble Your Kit + Notes
	Below is the total kit I used. As you can see, there aren't many tools required for this job at all. The choice of which Radiator / Electic fan to buy is up to you, either the £150 one or the £356, but the more reliable would be the BMW one. NOTE: After speaking to some one in the US, I was told that his radiator fan could be pulled out by only carrying out till Step #11, hence if your car is not the same model as mine, please check if the fan can be removed in this way, without taking the car apart as in Step #12 onwards.

2)	Engine Cover - Removal
	Remove the main big BMW cover (Intake Manifold) at the front of engine using this method:
1)	Remove the 2 clips at the front - pull up and then out the small round black pins (expanding rivets) with a flat head screw driver
2)	Un-clip the hook on the top left
3)	Remove the large hose on the top right
