What This Radiator Helps Address

  • Overheating caused by a leaking or restricted radiator
  • Coolant loss from cracked plastic tanks or aged seams
  • Reduced heat transfer from a worn or clogged core
  • Temperature instability during stop-and-go driving or towing
  • Cooling system service needs on OE-style replacement applications

Installation Notes and Tips

  • Verify the vehicle uses the listed down-flow configuration before installation.
  • Confirm inlet and outlet orientation: right-side inlet and left-side outlet.
  • Use the correct mini 13 psi cap specified for the application; cap is not included.
  • Inspect hoses, clamps, and coolant condition before installing the new radiator.
  • Flush the cooling system if contamination or debris is present.
