Chris, as Bob has already written, you have to drain at least some of the
coolant. However, there's no reason you can't drain it into a clean
container and reuse it if you're certain it's good.
But note that what deteriorates are the rust inhibitors, and most testers do
not test for them (only for glycol, which doesn't wear out). If it's been
in the car more than 2 years (even if the car hasn't been started/driven),
I'd take this opportunity to change it. When it starts looking rusty, there
has already been damage done ...
