Can anyone tell me the exact difference between the old gt500 washer reservoir and the new reservoir found in years 11-14? Can I swap out my new reservoir for an older style?
Probably shaped differently for a reason. It sits pretty close to the fascia, and the '11-'14 fascia isn't compatible with the '07-'09. So... You could probably put an old tank on a newer car, but not the other way around. And I think the '11-'14 tank is bigger than the older car's tank.
