If you're looking to replace the rear heater core in your 1987 Ford Mustang with the 5L V8 engine (E7TE), the OEM part number E7ZZ-18456-A is essential. This component is responsible for providing heated air to the rear passenger area. Common issues include leaks and reduced heating efficiency, typically due to corrosion over time. When inspecting, check for signs of coolant leakage and ensure the hose connections are secure. Installation requires removing the rear seat and accessing the core, so plan for some disassembly. Make sure to verify that the casting number D7ZZ-18456-B matches if sourcing from a junkyard to ensure compatibility across models from 1987. Always check for any discrepancies in connections or mounts before finalizing the installation.
