Slim Fit Radiator 79-93 Mustang Manual

The PROFORM Slim Fit Radiator 79-93 Mustang Manual is a direct-fit aluminum cooling solution engineered specifically for 1979–1993 Ford Mustangs equipped with manual transmissions. This slim-profile design fits within tight engine bay constraints without sacrificing cooling capacity, making it an essential upgrade for classic Mustang owners seeking reliable thermal management on street, show, or weekend cruise applications.

Built from aluminum construction, this radiator features a single-pass core design with passenger-side inlet and driver-side outlet configuration. The 29.109-inch width and 18.109-inch height profile allow seamless integration into original Mustang mounting points while the 4-inch depth accommodates standard cooling fan assemblies. At 29 pounds, the unit balances structural integrity with weight efficiency—important for vehicles where every pound affects handling balance. Manual transmission vehicles benefit from slightly lower cooling demands than automatic counterparts, and this radiator is precisely calibrated for that thermal load, avoiding oversizing that would compromise heater performance during cold-weather operation.

This radiator suits Mustang enthusiasts performing restorations, engine rebuilds, or routine cooling system replacement. Whether restoring a second-generation (1979–1986) or third-generation (1987–1993) Mustang, the direct-fit design eliminates custom fabrication and fitment guesswork. Natural aluminum finish allows for custom painting or polishing to match engine bay aesthetics. Pairing this unit with a modern electric fan system can further improve thermal efficiency and underhood airflow compared to original mechanical setups.
