The Temperature Switch 185 On / 165 Off by DeWitts Radiator is a precision-engineered component designed to automate the thermal management of your vehicle's cooling system. This electric switch serves as a critical interface between your radiator and electric cooling fans, ensuring that airflow is maximized only when necessary to maintain optimal engine operating temperatures. For enthusiasts looking to buy a reliable solution for heat regulation, this component offers a set-and-forget approach to cooling.
Technical specifications for the Temperature Switch 185 On / 165 Off dictate its specific operational window. The unit is designed to trigger your electric fan at a coolant temperature of 185 degrees Fahrenheit and disengage the fan once the temperature drops to 165 degrees Fahrenheit. This 20-degree differential is strategically selected to prevent rapid cycling of the fan motor, which can lead to premature wear of the electrical components and unnecessary strain on the vehicle's charging system.
Installation of this device is straightforward due to the 3/8 inch NPT male threading, a standard size found in most performance intake manifolds and radiator bungs. Utilizing a high-quality temperature switch is essential because it eliminates the need for manual toggles or less accurate probe-style controllers. By monitoring the coolant directly through the NPT port, the sensor provides real-time data that ensures the fan engages exactly when the engine requires additional airflow to prevent overheating during idle or low-speed operation.
When reviewing the requirements for a high-performance build, the integration of a Temperature Switch 185 On / 165 Off is often a top priority for maintaining consistent performance. The compact physical profile of 1.4 by 1.05 by 3.1 inches allows for installation in tight engine bays without interference. This electric switch is sold individually and provides the professional-grade reliability required for both street and track applications where thermal stability is paramount.
