Manufactured to OE specifications for fit, function and reliability, this 2-pin temperature switch helps maintain correct engine operating temperatures, protects against overheating and ensures efficient cooling system performance. It is an essential replacement item for maintaining the reliability of the vehicle's cooling system.

What This Product Does:

• Monitors coolant temperature within the cooling system.
• Activates the electric radiator cooling fan when required.
• Helps maintain optimum engine operating temperature.
• Prevents excessive heat build-up during low-speed driving or idling.
• Supports efficient cooling system operation.
• Protects the engine from overheating-related damage.

Symptoms Of Wear Or Failure:

• Cooling fan fails to operate when the engine reaches operating temperature.
• Engine temperature rises higher than normal.
• Engine overheating during traffic or idle conditions.
• Cooling fan runs continuously regardless of temperature.
• Inconsistent cooling fan operation.
• Temperature warning light activation.
• Reduced cooling system efficiency.
• Overheating during warm weather or heavy traffic conditions.

Why Replacement Matters:

• The fan temperature switch plays a critical role in controlling cooling fan operation and maintaining stable engine temperatures. Over time, repeated heat cycles, age and electrical wear can affect the switch's ability to accurately detect coolant temperature and activate the fan.
• A failed switch can prevent the cooling fan from operating when needed, significantly increasing the risk of overheating. Excessive engine temperatures can damage gaskets, seals, cooling system components and, in severe cases, major engine components.
