Standard Motor Products Engine Coolant Fan Switch

The Standard Motor Products Engine Coolant Fan Switch (also called a radiator fan switch, cooling fan temperature switch or coolant temperature fan switch) helps control your engine's cooling fan operation. It senses coolant temperature and signals the electric cooling fan to turn on and off at the right time, which helps keep operating temperature in the normal range.

Key Features:

• Monitors engine coolant temperature and triggers the cooling fan at the calibrated temperature point
• Helps prevent overheating in stop-and-go traffic and at idle
• Helps avoid unnecessary fan operation, which supports efficient engine warm-up and fuel economy
• Engineered by Standard Motor Products, a well-known supplier of engine management and electrical components
• Designed to meet or exceed original equipment form, fit and function

A failing fan switch can cause overheating, a fan that runs constantly, or a fan that never turns on. Replacing it helps restore reliable cooling system performance. Choose the exact part number for your application from the options listed on this page.
