  • Coolant loss from cracked plastic tanks or aged core seams
  • Poor heat transfer from a worn aluminum core
  • Cooling system service needs on a 2004-2005 Mitsubishi Lancer
  • Replacement of an OE-style down-flow radiator with matching inlet and outlet locations

Installation Notes

Confirm clearance for the integrated oil cooler connection and compare the original radiator dimensions to the CSF 3128 before installation on your Mitsubishi Lancer.
