Facet Engine Coolant Temperature Switch

The Facet Engine Coolant Temperature Switch (also called a coolant temperature sensor, engine temperature switch or cooling fan temperature switch) monitors engine coolant temperature and sends a signal when it reaches a set point. Depending on the application, that signal can control the electric cooling fan, feed temperature data to the engine control unit, or drive the dashboard temperature gauge or warning light.

Key Features:

• Senses coolant temperature so the cooling system can respond to changing engine conditions
• Helps the engine stay in its normal operating temperature range
• Supports reliable cold starts, fuel management and fan operation when the signal is used by the engine management system
• Made to meet the fit and function of the original equipment part
• Sealed construction resists coolant, heat and vibration

Facet is a European aftermarket manufacturer of fuel pumps, ignition components, sensors and switches. A failing coolant temperature switch can cause overheating, a fan that runs constantly or not at all, poor fuel economy, hard starting or a false gauge reading. Replacing it restores accurate temperature sensing and dependable cooling control.
