    Replacement Fan Clutch For original and reproduction C8OE-B 390 390GT 427 & Early 428 Cobra Jet Fan

    Reproduction thermal fan clutch that fits 1967-68 289 engines, 1968 302/390/427/428CJ engines, and 1969 351W engines, all with original Ford thermal cooling fans. Slightly larger in overall diameter, (still fits fine), and retains the correct spacing from radiator. We know that these will fit Mercury Cougar and Ford Mustangs 1967-69.

    Closest reproduction fan clutch on the market that fits the original and reproduction C8OE-B 7 blade power fan. Hayden fan clutch with an overall height of 2.98 inches. Similar design as originals, with thermal activated clutch. Overall diameter is 7.20 inches. Application for the C8OE-B 7 blade fans include 1968 390-2V, 390-4V, 427-4V, and 428CJ engines, additionally this fan was installed on the 1969 Mercury Cougar and Ford Mustang with S code 390-4V or 390IP engines.

    • Varies the fan speed with temperature of the air behind the radiator.
    • Engaged (high speed) operation provides maximum cooling.
    • Disengaged (low speed) operation provides fuel savings and noise reduction.
    • Greater life expectancy than a non-thermal clutch.
    • Briefly engaged at cold start-up.
    • Engages at about 170° radiator air temperature, (about 30° lower than coolant temperature).

    The air temperature coming through the radiator is sensed by the bi-metal thermal spring on the front of the thermal fan clutch. It expands and contracts with the change in air temperature operating a valve inside of the clutch. When cold, the silicone drive fluid is pumped from the working area to the reservoir. When hot, the valve opens allowing fluid from the reservoir to be transferred to the working area thereby increasing the fan speed. The clutch disengages as the air temperature decreases, closing the valve and allowing the silicone fluid to be pumped back into the reservoir.

    A thermal fan clutch is engaged on a cold startup because the fluid drains into the working area when the engine is shut off. The fan clutch will slow down shortly after startup as a result of a pumping action produced by a difference in speed between the shaft and the body of the clutch.
