The Flex-A-Lite Variable Speed Controller and Relay Kit (Model 31163) is a precision automotive fan controller featuring a built-in relay and a threaded temperature sensor with multiple adapters. It operates fans starting at 60% power, increasing speed as engine temperature rises between 160°F and 240°F, and continues cooling for 25 seconds after shutdown to protect your radiator. Engineered for dual-fan electric systems, this USA-made, machined black controller offers seamless installation and reliable thermal management.
