There's a drain plug for the coolant on the thermostat housing (bottom, driver side corner of radiator). You only need to drain enough so that the coolant tank can be removed (about 2-3 quarts). Most single-use clamps can be replaced with standard clamps. The only sensor connection that's tricky is the passenger sider intake runner flap sensor (one of the two under the front carbon-fiber cover). Get a piece of stiff wire, grind down one end so its flat like a screw driver and bend it in the necessary shape to un-clip the sensor. The Bentley CD instructions for the removal is 13 pages, so its hard to give all the tips in one post.
