It is just plastic and aluminum so it canjust go in the trash, right. I can't imagine you would want a rebuilt radiator, but if a shop would buy the core off me, I would be happy to take the $$. Got a stock replacement. Looked at a Fluidine, which would have been nice, but would have had to do more work to make it work, and figure the stock radiator, while a weak, plastic, epoxy and aluminum piece of shit, will last another 7 years and 125,000 miles, which is probably longer than I will have the car.
