Having problems with your 1997 Pontiac Grand Prix ?
How do you know when your radiator needs flushing
There is a tester u can buy at an auto store that checks the potency of the existing anti-freeze especially if u just purchased the car used....no telling when the last owner flushed it.....it all depends on mileage...every 30,000 or more is sufficient unless u have had radiator problems with dirt and gunk in them....
