  • Restricted coolant flow from an aging core
  • Damaged inlet or outlet connections
  • Oil cooler connection wear at the radiator assembly
  • Overheating caused by reduced heat transfer efficiency

Verify inlet and outlet orientation before installation: inlet diameter is 1 3/8 in. on the left and outlet diameter is 1 1/2 in. on the right. Confirm the vehicle uses the OE-style quick-connect outlet pipe and quick-connect oil cooler fittings shown in the specifications. Transfer any required components from the original radiator as needed, and inspect hoses, clamps, and coolant condition before refilling the system.
