    All engines

Intended for compatible 1986–1993 Ford Mustang applications. Verify exact engine size and configuration before ordering. Cooling hose routing can differ between engine options. Confirm radiator inlet and outlet locations. Check thermostat housing orientation. Verify water pump connection points. Confirm heater-core and bypass hose routing. Check hose inside diameters before installation. Verify clamp size and type for every connection. Aftermarket radiators may use different neck diameters or positions. Engine swaps can significantly change hose requirements. Supercharger, turbo, or custom cooling modifications may affect fitment. Do not allow hoses to contact belts, pulleys, fans, sharp edges, or exhaust components. Recheck all clamps after the first heat cycle and inspect for leaks.
