Once this black hole consumes the entire car, will it stop? Or is the neighborhood,state, country & solar system next? Is ANYONE SAFE????

I’ve got to change my coolant reservoir as it is leaking streams of orange coolant on my garage floor after spirited driving. Uro part is in box waiting patiently for me. I called last Indy who did most recent flush (previous owners guy) and asked which coolant he had put in it. Orange DEX or non-DEX. He couldn’t remember and deferred to Porsche. I suspect that Porsche would want me to come in for a full flush and move to pink or purple coolant. I’m going to lose about a quart when I pull the reservoir so don’t really want to replace/flush all coolant that’s about six months old. Any thoughts on mixing DEX and non? I’ve got a 50/50 shot at guessing right
