Confirm vehicle fitment by year, model, and cooling-system configuration before installation. The 2007-2008 Toyota FJ Cruiser application is listed with an oil cooler, and the 1993-1997 Toyota Corolla application includes the noted dimensions. Inspect hoses, clamps, caps, gaskets, and related cooling-system components during replacement so the new radiator can be installed on a clean, leak-free system. Verify all mounting points and connections match the vehicle before filling and bleeding the cooling system.
