Verify reverse rotation, flange mount dimensions, bolt pattern, and pilot measurements before installation. Mounting hardware is not included. Confirm the fan bolt circle, clutch diameter, and overall height match the original unit on the vehicle. For best results, inspect the radiator, water pump, and fan blades during replacement to ensure the cooling system is operating correctly.
