Common Cooling Issues It Can Address

  • Overheating caused by a leaking or restricted radiator core
  • Coolant loss from cracked or aged plastic tanks
  • Reduced heat rejection from a worn factory radiator
  • Cooling system service needs on Ford Ranger and Explorer platforms
  • Fitment replacement for vehicles using the specified cross-flow, 1-row layout

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this unit uses a left-side inlet and right-side outlet. Confirm the vehicle uses the correct 1-row, cross-flow configuration and the proper 1 1/2-inch hose connections. The radiator cap is not included, so reuse or replace the cap separately as needed. For best results, inspect hoses, clamps, and coolant condition during radiator replacement.

Quality Assurance

CSF states that its factories are ISO/TSO certified and that its radiators are engineered and wind-tunnel tested for cooling performance validation. Part number 3277 is built to OE-style standards for consistent fitment and cooling-system service.
