This engine cooling fan clutch uses a thermal control that responds to under-hood temperature: it drives the fan when the engine runs hot and lets it slow as things cool, which helps limit fan drag, noise and unnecessary load.
Backed by Hayden's decades of automotive cooling experience. Country of origin: Mexico.
What does the Hayden 2710 fan clutch do?
It's a thermal fan clutch that couples the engine cooling fan to the fan drive. It drives the fan when the engine is hot and lets it slow as things cool, helping limit fan drag and noise.
Will this fan clutch fit my vehicle?
It's a direct-fit replacement for many vehicles, including the 1975-1987 Ford F-150 4.9L / 5.0L / 5.8L / 5.9L / 6.4L and 1961-1987 Ford F-250 3.6L / 3.9L / 4.9L / 5.0L / 5.8L / 5.9L / 6.4L. See the Buyer's Guide tab for the rest.
Is mounting hardware included?
No. Mounting hardware is not included. Consult the vehicle service information for the correct fasteners and whether they may be reused.
What are signs my fan clutch may need replacing?
Possible signs include engine overheating at idle or low speed, a continuously loud fan roar, a fan that freewheels, or fluid seepage. Diagnose the cause before replacing, as other cooling components can produce similar symptoms.
What does standard rotation and thermal mean on this clutch?
Standard rotation (STD) matches the factory drive direction for the listed applications, and thermal means it uses a temperature-sensitive control rather than an electronic one. It is a non-electronic, standard-duty unit.
