With the smaller coolers (I'm not sure about the larger coolers on the S model) this is not an issue. I did not drain the coolant. I had some clean rags and lifted the cooler straight up after removing the bolts and quickly put the rags under the cooler. Make sure you clean all surfaces before putting the new seals in-place. After you get the cooler re-mounted remove the coolant fill cap and make sure you flip up the coolant bleeder valve to get all the air out of the system (while running the motor), add a little Porsche coolant if needed. This really is an easy job.
