Spring type

Hello, what parts are you looking for? With all respect, Amazon is a horrible place to search for parts. I would suggest trying a local parts store or dealership near you for the best possible experience and trouble free fitment. I don't have any idea what springs have to do with cooling system or engine components. It's likely that the information Amazon is seeking is about the vehicle in whole but don't have anything do with the parts you are seeking. That said, have you performed testing for the concerns you are experiencing?
