Keep cold air blowing through your dash vents with the Four Seasons A/C Evaporator Core 64177, a parallel-flow evaporator core that drops in as a direct-fit replacement for the 2021-2025 Ford Bronco. Inside the HVAC case, the evaporator core is where liquid refrigerant absorbs heat from the cabin air passing over it, cooling and dehumidifying that air before it reaches the vents — so a leaking or clogged core means weak cooling, refrigerant loss, or a musty smell.

  • Parallel-flow core design: engineered so its core design meets or exceeds OE performance and efficiency.
  • Optimized refrigerant flow: the internal passages are designed for optimized refrigerant flow through the core.
  • Application-specific design: built to the specifications of the listed vehicle for a proper fit.
  • Includes sealing components: contains gaskets, o-rings, or seals to properly replace the product.

Backed by over 50 years of mobile A/C experience from Four Seasons. If a failed evaporator core is the cause of your weak or lost A/C cooling, this replaces it.
