Decent coolant reservoir
This reservoir was the same size and profile as original. It didn’t have a bumper pad as original so I had to make my own since old one could not be swapped over. New tank lid did not come with a gasket on the cap. I called customer service and he was very courteous and sent me out a replacement but that lid was also missing a gasket. I was a little disappointed I had to use original cap on a new reservoir tank.
