ACDelco Gold 15-80278 (19189693) Engine Cooling Fan Clutch

ACDelco Professional Engine Cooling Fan Clutches control the speed of the radiator fan based on the temperature of the air after it passes through the radiator fins, and are the ideal high quality replacement for your GM vehicle. The clutch contains a special viscous silicone fluid that transfers force between the two halves of the clutch. A bi-metallic element on the front of the clutch housing controls an internal valve that regulates the clutch engagement. When the radiator is cold, the fan clutch slips, and when the radiator is hot, the clutch is engaged. There are some electromagnetic fan clutches that perform similarly to the viscous fan clutch. These Professional, premium aftermarket replacement engine cooling fan clutches are manufactured to meet or exceed your expectations for fit, form, and function.
