Non-Thermal Fan Clutches operate based on the shaft speed of the water pump. At low and idling speeds the clutch allows the fan blade to turn at almost a 1:1 ratio. At high speeds the silicone fluid contained in the clutch will lose its ability to transfer the energy from the shaft to the fan clutch body (and therefore the fan) and the fan is then allowed to almost free-wheel, removing its load from the engine.

Features & Benefits

  • Low cost alternative for some standard thermal clutches.
  • Spins at about 30-60% of the water pump speed.
  • Cannot replace a heavy-duty clutch.
  • Identified by the smooth, steel faceplate, (without a thermal spring assembly), on the front.
