Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line connections, and overall dimensions before installation. Flush the cooling system, inspect hoses and clamps, and confirm that the radiator mounts and fan shroud alignment match the original setup. Because this unit includes internal engine oil cooler and internal transmission oil cooler sections, check all fluid circuits for leaks after installation.
