Re: colling system
It's probably the same radiator, just by a different manufacturer. It would depend on whether you want to keep all OEM parts on it (more expensive) or go with aftermarket stuff, which is obviously less expensive. What kind of warranties are one each one? How many miles is on this vehicle? If taken care of, a radiator shouldn't fail all that often, especially on a newer vehicle.....unless it's got a ton of miles on it.
