Four Seasons 64173 rear a/c evaporator core for the 2020-2025 Ford Explorer and other vehicles is the plate and fin coil that cools cabin air as refrigerant flows through it.
Weak cooling at the rear vents or oily residue around the rear A/C connections can mean the evaporator core is failing. Those signs can also come from elsewhere in the system, so with the engine off, look over the visible fittings for oil stains and have a shop leak-test the system before you replace the core.
The same core fits the 2020-2025 Lincoln Aviator and the 2020-2025 Ford Interceptor Utility. If your vehicle isn't named here, run its year, make and model through the Buyer's Guide tab before you order.
Gaskets, o-rings or seals for a proper replacement.
