Flex-a-lite 33054 Variable Speed Control Replacement Kit;

Flex-a-lite's developed a new variable speed control to actuate engine cooling fans. The Variable Speed Control (VSC) can be set between 160 and 220 degrees and senses cooling temperature via the radiator core. The VSC will vary the fan speed from 60 to 100 percent depending on engine cooling needs, and will operate the fan at 60 percent when air-conditioning is on. VSC features a built in 5-second delay to reduce charging spikes at start-up, and a 30 seconds delay after shut down if additional cooling is needed. A terminal for Flex-a-lite's manual switch allows the electric fan to be turned off through water crossings.
