Standard Motor Products Coolant Fan Switch

The Standard Motor Products Coolant Fan Switch (also called a radiator fan switch, engine cooling fan temperature switch or coolant temperature fan switch) helps control your engine's electric cooling fan. It senses coolant temperature and turns the fan on and off as needed, so the engine stays within its normal operating range.

Key Features:

• Monitors engine coolant temperature and activates the cooling fan at the correct point
• Helps prevent overheating in traffic, at idle and under heavy load
• Helps the fan run only when needed, which supports efficient engine operation
• Built to meet or exceed original equipment requirements for fit and function
• Made by Standard Motor Products, a long-established supplier of engine management and temperature control parts

A failing fan switch can leave the fan stuck on or off. Symptoms include overheating, poor air conditioning performance at idle, and a fan that runs constantly. Replacing the switch restores reliable fan operation and helps protect the engine and cooling system.
