Can I drive my car a few miles with a leaking radiator before it reaches red zone?

I owe you guys an apology. I referenced an old write-up and set of instructions that I had come across that are slightly different than what you provided me. Those are the ones that got me confused and didn't show numbers matching the photos: https://www.2carpros.com/questions/saab-9-3-1999-saab-9-3-1999-saab-9-3-removal-radiator

Anyhow, thanks again.
