Direct Replacements / Fitment
This switch is designed to replace the following part numbers:
For Horton 993653
For Medallion 1002-05554-31
For Medallion 1002-05850-31
Function & Purpose
How it Works: As a "Normally Open" switch, the circuit is open (off) at normal temperatures. When the engine coolant temperature reaches 195°F, the switch closes (on), completing the circuit to engage the fan clutch.
Benefit: This provides on-demand cooling, optimizing engine temperature for performance and efficiency. It helps save energy by only running the fan when necessary.
Package Includes
1 x Temperature Switch
The 8037026P is a direct, high-quality replacement temperature switch that will reliably engage a vehicle's cooling fan at 195 degrees Fahrenheit, ensuring optimal engine temperature control. It is compatible with systems designed for Horton and Medallion switches.
