Flex-a-lite variable speed controllers attach on or near the electric fan, sensing coolant temperature via a radiator probe or temperature sending unit. They set fan speed from 60 to 100 percent, depending on the built-in thermostat's setting. The thermostats have a range of 160-220 degrees F. The variable speed controllers allow greater control over engine temperature, which helps to reduce charging spikes and current load on the charging system. They keep the fans running for 30 seconds after your vehicle is turned off.
