I tried my best to flush out the PO's green prestone coolant and I filled it up with G05.

While I believe I was able to flush most of the green stuff out, there's still a ever so slight green tinge to the coolant....

I realize this will it make it slightly more prone to corrosion, but how much worse?

"It'll probably be fine, just change it in 3 years"

or

"Reflush it... hope you haven't destroyed your cooling system after driving on it for 2000 miles"

There's a list of things I need to have done to the car, I'm just trying to prioritize.
