Facet Engine Cooling Fan Switch

The Facet Engine Cooling Fan Switch, also called a radiator fan switch or cooling fan thermo switch, controls when your engine's electric cooling fan turns on and off. It reads coolant temperature and signals the fan to run when the engine needs more cooling. This helps keep operating temperature stable in traffic, at idle and under heavy load.

Key Features:

• Temperature-activated switching that engages the cooling fan at the right time
• Helps prevent overheating and the engine damage it can cause
• Helps avoid running the fan longer than needed, which supports efficient engine warm-up and operation
• Built to meet or exceed OE form, fit and function
• Made with durable materials for reliable performance in under-hood heat and vibration

Facet is a long-established European manufacturer of automotive fuel, ignition and engine management components. Replacing a worn or failed fan switch restores proper cooling system operation. Symptoms of a bad switch include a fan that never runs or runs constantly, and engine overheating.
