Facet 7.5186 Engine Cooling Fan Temperature Switch

The Facet 7.5186 is a precision-engineered engine cooling fan switch designed to automatically regulate radiator fan operation based on coolant temperature. This temperature-sensitive switch activates the cooling fan when coolant reaches a specific threshold, helping prevent engine overheating and maintaining optimal operating temperatures.

Key Features:

• Factory-calibrated bimetal disc technology provides precise temperature activation
• Direct replacement for OEM parts including Suzuki 1768050F10000, Subaru 1768050F10, and General Motors 96065719
• Designed and manufactured in Italy to OE-equivalent quality standards
• Threaded installation design for secure, leak-free mounting in radiator or engine block
• Lightweight construction at approximately 2.1 ounces (59 grams)
• Engineered to withstand harsh engine compartment conditions including heat, vibration, and coolant exposure

How It Works:

The switch utilizes a bimetal disc composed of two metals with different thermal expansion coefficients. When coolant temperature rises to the calibrated set point, the disc snaps and closes electrical contacts, sending a signal to activate the cooling fan motor. As the coolant cools and temperature drops below the threshold, the contacts open and the fan shuts off, maintaining consistent engine temperature.
