Verify radiator dimensions, inlet and outlet sizes, and cooler line spacing before installation. This radiator is a direct-fit style replacement for the 2004-2006 Lexus RX330 with tow package, so matching the original configuration is important for proper installation. Inspect hoses, clamps, and cooler lines for wear before reassembly to help prevent repeat leaks.
