009 Cooling System Upgrades Chillin Out
|
Controlling an electric fan can be as basic as using the properly sized wiring through a high-amp relay and a toggle switch on your dash. However, we suggest a thermostatic switch of some sort, as a toggle switch can be forgotten in the heat of stop and go traffic. A basic thermostatic switch can be inserted into the water jacket of the engine or into the radiator core. The Flex-a-lite variable-speed fan controller is just one option shown here. The controller senses coolant temperature at the radiator and can turn the fan speed on from 60 to 100 percent. View Related Article
