Standard Motor Products TS116 Engine Coolant Fan Switch

The Standard Motor Products TS116 is a direct-fit replacement engine cooling fan switch, also sold under the Intermotor brand. This temperature-activated switch monitors coolant temperature and signals the electric radiator cooling fan to engage and disengage at the correct threshold, helping maintain optimal operating temperature and protect the engine from overheating.

Key Features:

• Engineered to meet or exceed original equipment (OEM) specifications for precise fit, form, and function
• Features a custom wax pellet design that expands when heated, activating a snap-action electrical contact that sends the signal to the fan controller
• Incorporates a formed bimetallic contact arm that uses the different expansion rates of two fused metals for creep-action actuation and consistent performance
• Each unit is individually calibrated and tested to confirm switch actuation at its specified temperature
• Robust construction using high-grade materials designed to withstand the demands of daily use
• Sold individually
