Fix my orignal radiator or just replace??

If the radiator is original to the car then yes have it repaired but if its not then I would go aftermarket just please do your homework on radiator brands there are plenty of choices from super cheap to high dollar but in my humble opinion rads are a you get what you pay for kind of item and the cheap rad is all fine and good till you overheat and are stranded on the side of the road (ask me how I know this one)
