What It Helps Address

  • Reduced heat dissipation from clogged or damaged cooling passages
  • Temperature instability during stop-and-go driving
  • Cooling system service on a Ford Fusion, Lincoln MKZ, or Mercury Milan

Installation Notes and Tips

Verify inlet and outlet hose sizes before installation. Confirm radiator dimensions against the original unit and inspect related cooling system parts, including hoses, clamps, thermostat, and coolant condition, before returning the vehicle to service. Proper system bleeding is important after installation to remove trapped air and restore normal coolant circulation.
