I've seen a few of you that have replaced your diverter valves. I need to do my wife's CM. However, there's a water hose in the way that I can't seem to get loose. Does anyone know of some detailed instructions for replacing the valve on the CM? any I see out there are for the regular Cooper S cars

Thanks in advance!

 

Is it the hard-line that connects to the turbo? Or do you mean the hose that runs to the expansion tank?
The hard line isn't an issue, as you can wiggle around it. The soft line that goes to the expansion tank just gets pushed out of the way when you undo the expansion tank and move it out of the way. It isn't the easiest process, but it definitely works. I removed and installed mine at least 15 times without disconnecting any lines or hoses. after the first few times, it becomes pretty easy to do
