This answer was rated:

Is it better as a small repair shop to get a machine that cleans and renews a vehicles coolant as opposed to replacing it, or a machine that removes the old coolant, and replaces it with new coolant? What are the pros and cons of each?
I would go with removing the old and putting in new. The pros and cons are that it is less expensive to reuse the coolant but will not be as clean as the new. Also electrolysis is more likely to happen in used coolant so in the long run better off to spend a little more money and put new in.
