Electric Cooling Fan Faq Learn how to properly wire single or dual electric cooling fans using a relay kit and a temperature sender. see diagrams, video and tips for high horsepower applications. Learn the benefits and methods of wiring dual electric fans for your car's cooling system. see a diagram and instructions for using two relays and one thermostatic switch.
How To Properly Wire Electric Cooling Fans The cooling fan wiring diagram below is what we’ve found to be the simplest and most reliable method. it uses a 40 amp electric relay and electric fan sensor. start your wiring project by taking both of the positive wires from the fans and run them to the yellow wires on each relay (tab 87). Use wire connectors to secure the wires. connect the wires: connect the red wire of the cooling fan to the positive terminal of the power source and the black wire to the negative terminal. if the cooling fan has a yellow tachometer wire, connect it to the appropriate pin on the motherboard for monitoring fan speed. The gauge of the wire that you use in your cooling system wiring harness is very important. spal’s greg goeders explains why you need to make sure you’ve got the right size wiring running to your cooling fan. “you have to make sure the wires used to power the fan are ample sized for the electrical load the fan is expecting to see. This wiring diagram shows the connections between the various components in the system and how the fans are activated. the diagram typically includes the following components: thermostat: this temperature sensitive switch activates the cooling fans when the engine reaches a certain temperature. fan relay: the relay is responsible for.

Step 3: install the electric fan relay. after wiring the electric fan to the proper power source, the next step is to install the electric fan relay. the electric fan relay is an important component that controls the operation of the electric fan. it acts as a switch, turning the fan on and off when needed. Yes, you can. but it is risky. the electric cooling fan setup has a high amp draw on start up, which can blow the 30 amp fuse that protects the relay and wiring. most relays have a 30 amp fuse. if this fuse blows, the cooling system goes offline, meaning the engine will overheat. a dual fan setup with a large and small fan.
