Pulling vacuum after third radiator install on 991.2
This question is for those have have installed a third radiator or maybe just used a vacuum purge tool on the existing 2 radiator 991.2 system. What is the expected psi that should be able to be achieved when pulling a vacuum on a system that was not fully drained? Vacuum tool would be the Schwaben Air purge Tool.
There is an entire routine prescribed by Porsche for coolant replacement involving warming, engine revving and the like. I suggest that you get ahold of the technical repair book

Does anyone have a link to Porsche document? Would be neat to see since there are quite a few suggested methods. Thanks
