Keep your mechanical cooling fan working with under-hood temperature using the US Motor Works Thermal Fan Clutch (MPN 22157). It installs as a direct-fit replacement across a wide range of 1999–2020 GM trucks, vans, and SUVs — including the Chevrolet Silverado 1500/2500, Suburban, Tahoe, and Express, plus the GMC Sierra, Savana, and Yukon and the Cadillac Escalade — with V6-4.3L, V8-4.8L, V8-5.3L, and V8-6.0L engines. See the Buyer's Guide tab for the full list of 49 applications.
A thermal fan clutch drives the engine cooling fan when the engine is hot and lets it freewheel as things cool, so the fan pulls air when it is needed. If a worn or seized clutch is the cause of your cooling problem, this replaces it.

What does this fan clutch do?
A thermal fan clutch engages the mechanical cooling fan when the engine is hot and lets it freewheel when cool, so the fan draws air only when it's needed.
What vehicles does MPN 22157 fit?
Direct-fit for many 1999–2020 GM trucks, vans, and SUVs — Silverado, Sierra, Suburban, Tahoe, Yukon, Express, Savana, and Escalade — with V6-4.3L, V8-4.8L, V8-5.3L, or V8-6.0L engines. See the Buyer's Guide tab.
What are signs my fan clutch may need replacing?
Signs include a constant fan roar, the fan freewheeling with poor cooling at idle, silicone fluid leaking from the clutch, or a loose, wobbling fan. Diagnose the cause before replacing.
Does it include fan mounting hardware?
Yes. This clutch ships with the fan mounting hardware.
Which way does this clutch rotate?
It is a counter-clockwise rotation fan clutch. Confirm it matches your vehicle's fan rotation before installing.
