What This Radiator Helps Address

  • Overheating caused by a failing or restricted radiator
  • Coolant leaks from cracked tanks or worn core assemblies
  • Reduced cooling efficiency from damaged fins or internal blockage
  • Transmission cooling concerns when the radiator’s cooler circuit is compromised
  • Fitment issues when replacing the original Chrysler PT Cruiser radiator

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler connections before installation. Flush the cooling system, inspect hoses and clamps, and confirm the fan, thermostat, and coolant condition are in good working order before installing the new radiator. Proper bleeding of the cooling system helps prevent air pockets after service.

Quality Assurance

Denso radiators are manufactured to OE-level standards and undergo durability and function testing before release. That testing process supports reliable performance and proper fitment for Chrysler PT Cruiser cooling system service.
