Keep your cooling fan spinning in step with underhood temperature with the Hayden Cooling Fan Clutch 2947, a standard-rotation, thermal heavy-duty unit designed, tested, and built by application. It drops in as a direct-fit replacement for the 1988-1991 Chevrolet C1500 and K1500 [V8-5.7L], the 1975-1986 Ford F-150 [V8-5.0L], the 1977-1985 Buick Riviera [V8-5.7L] and hundreds more — see the Buyer's Guide tab for the full list.
A thermal fan clutch uses a temperature-sensitive coupling to drive the fan harder as the air behind the radiator heats up and to freewheel when it's cool, which helps restore proper airflow while limiting fan noise and parasitic drag on the engine.
Backed by Hayden's decades of automotive cooling experience, it meets or exceeds OEM requirements for fit and appearance. Country of origin: Mexico.

This part cross-references / interchanges with the following part numbers:
What is an engine cooling fan clutch and what does this one do?
It's a temperature-sensitive coupling between the fan drive and the cooling fan. This thermal unit drives the fan harder as underhood air heats up and freewheels when it's cool, helping maintain airflow while limiting noise and drag.
Does the Hayden 2947 include mounting hardware?
No. Mounting hardware is not included — consult your vehicle's service information for the correct fasteners and whether they may be reused.
Will this fan clutch fit my vehicle?
It fits hundreds of applications — see the Buyer's Guide tab for the full list of years, makes, models, and engines. Confirmed examples include the 1988-1991 Chevrolet C1500 and K1500 [V8-5.7L] and the 1975-1986 Ford F-150 [V8-5.0L].
What are the signs a fan clutch may need to be replaced?
Signs it may need replacing include engine overheating, a fan that roars continuously, excessive fan noise, or a loose/leaking clutch. Diagnose the cause before replacing, since overheating can have other causes.
What are the key specs of the Hayden 2947?
It's a standard-rotation thermal heavy-duty fan clutch made of aluminum, with a 7.2 in overall diameter, a 4-bolt flange mount, 5/16 in-18 bolt threads, and a 2.71 in spacer length.
