What It Helps Address

  • Cracked or leaking radiator tanks
  • Corrosion or damage in the original aluminum core
  • Restricted coolant flow from an aging radiator
  • Overheating caused by a failing factory radiator
  • Cooling system service on a 2010-2013 Mazda 3 or Mazda 3 Sport

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this radiator uses a left-side inlet and right-side outlet. Confirm core dimensions and mounting layout against the original unit before removal, and inspect hoses, clamps, and coolant condition during service. For best results, flush the cooling system and check for leaks after installation.
