If you’re reading this and about to install the CBC, do yourself a favor and remove the coolant pump and drain the coolant. I barely got the fan shroud out with the pump in but I could not reinstall with the coolant pump installed so I removed it and the fan shroud slid right in. Also, bleeding the cooling system on the s55 has a specific procedure. I did it 4 times and the coolant level never dropped. I had to drive the car until the drivetrain warning came on (coolant pump dry running) filled the reservoir, drove it again, dt warning, topped off, drove it again, no dt warning but coolant level dropped a bit so I topped it off. I drained all the coolant into a clean bucket so I knew how much coolant had to go back into the system. Hope this helps!
