Engine Cooling Fan Switch for Chrysler and Dodge

Standard Ignition TS-165 is an engine cooling fan switch built with a formed bimetal contact arm and factory-calibrated actuation points. It uses a snap-action electrical contact to send the signal to the fan controller when the specified temperature is reached.

• Female connector gender
• Male blade terminals
• 2-terminal design
• Factory-calibrated and tested for switch actuation at the specified temperature
• Wax-pellet and bimetallic thermal switching design for precise electrical contact movement

Detailed Product Information

The TS-165 is an engine cooling fan switch from Standard Ignition, engineered for service work where accurate temperature-based fan control matters. The thermal element expands when heated, triggering the electrical contact to transfer the signal to the fan controller. Standard Ignition calibrates each unit during production to confirm the lower-temperature set point and verify proper operation. This part cross-references Gates 51766 for the same application.
