Because mixing types (Not up on the exact different types) of coolant can cause serious issues. if you currently have Porsche Antifreeze, you would need to flush it out completely before replacing it. I flushed mine twice before refilling with Porsche coolant from Porsche coolant. I'm not sure I flushed out all of the old. I think you would have to pull the hoses off the radiators and make sure they were drained
