Keep the cabin cold with the Four Seasons A/C Evaporator Core (P/N 64145), a parallel-flow evaporator that installs as a direct-fit replacement for the 2013-2019 Cadillac ATS and 2014-2019 Cadillac CTS. Inside the HVAC case, low-pressure refrigerant expands across the core and absorbs heat from the air passing over it, sending cold air into the cabin.

  • Parallel-flow core: optimized refrigerant flow through the core for efficient heat transfer.
  • Application-specific design: built for the listed vehicles for a straightforward fit.
  • Sealing hardware included: contains gaskets, o-rings, or seals to properly replace the product.
  • Backed by Four Seasons: engineered and tested with over 50 years of mobile A/C experience.

Signs the original evaporator core may need replacing include weak or warm airflow from the vents, a refrigerant leak inside the HVAC case, or a musty smell. If a failed evaporator core is the cause, this replaces it. See the Buyer's Guide tab for engine-level fitment for your vehicle.
