How to Wire a Cooling Fan to Your Car (DIY Electric): 9 Steps

This ignition wire will be in your cabin under the dash connected to your key system. Here you'll also learn about duty-cycle controlled cooling fans. The older trusty relay is also used, but how it is controlled is what has changed. Here you'll also be exposed to the current path, voltage and sensor signal input. The Hyundai Sonata is a mid-size sedan manufactured and marketed globally by Hyundai Motor Company since its introduction with model year 1988. The hydraulic cooling fan is integral to the fan shroud and is located between the radiator and the engine.

If so do you know if they come in different temperature turn-on specifications? Since the wire is now connected we need to do a safety tip! Part of our wiring diagram training series here on this channel. This switch is controlled by the thermostat and closes to complete an electrical circuit when electricity needs to be supplied to your condenser fan motor and compressor. We will be using a butt connection to fuse these together. Since my engine is not stock 1971 Riviera 455 cubic inch big block the cooling fan previously that was installed is just not enough to cool it down. Herein you will find also detail information about service, troubleshooting and testing procedures for power cord, motor capacitor, fan motor winding, compressor motor winding, thermistor, electric heater, blower wheel, evaporator, condenser, propeller fan, and fan motor.

This will likely be back to your contactor. Take some zip ties and tie them to a stationary place in your engine bay! The dealer will charge you 400 to pull the bumper off, or you can buy the part for 45 and cut the hole in the plastic near the passenger headlight assembly and replace it yourself. Then use the thermostat for the switch cause they are low volts. I suspect you were not getting power to the fan motor so you will need to take a look at the radiator fan relay, this is a special solid state relay mounted to the inside of radiator core support on the right side down behind the bumper. Switches arent designed for high voltage and abuse but the relay is. Now easily tape the wires and butt connection to hold it in place. Voltage drop at the dash harness is reduced, and overall switch and electrical system performance and longevity are enhanced.

Radiator Fan Relay

A relay is a type of heavy-duty remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. The change over relay is at rest and provides a path between pin 3 and 4 to the right fan motor, the circuit is complete at pin 2 of the right fan motor when returning to earth. So now we have a wire that goes through the engine bay to the cabin of your car! Safety is always the highest priority. Perhaps you need to activate an electric fan or nitrous system by means of an automatic switch. The wire through the fire wall will now be connected to the switch.

I would swap the sensors depending on the season. This provides automatic fuel pump shutdown after a crash or engine failure, and also prevents the fuel pump from running if the ignition is left on. In 12-volt automotive electrical circuits, even small amounts of resistance can cause significant amounts of voltage drop. When the relay is energized turned on , the high current required to operate the accessory flows from the power source, through the relay, and directly to the part. A far better solution is to use a relay. When the engine stops running, oil pressure drops, the switch opens, and the relay de-energizes. This guide will explain how to wire your new condenser fan motor using a four wire setup or a three wire setup when using a single run capacitor or a dual run capacitor.

The switching of the power circuit is done by the 3 relays which, are controlled by the control unit. You can use a wire nut and electrical tape to tie it off. Therefore any failure of the fan blade, hydraulic fan drive or fan shroud requires replacement of the fan module because the fan blade and hydraulic fan drive are matched and balanced as a system and servicing either separately would disrupt this balance. High pressure line from steering gear pump to hydraulic fan motor; 4. Now take that blue wire and tap into the red wire after the fuse and tape it up! This can cause the voltmeter at the dash to display a significantly lower voltage than the actual battery voltage.

The factory headlight switch and beam-select switch need only energize the relay for it to send full battery power into the front lighting system harness. Simply wire the common lead white to the common terminal, the contractor lead solid brown to the F terminal, and whatever lead came from the compressor and you should be set. The troubleshooting sections describes detail symptom, probable cause and remedy of the problems e. Think of the contactor almost as a gatekeeper — two legs of 115 volt electric supply need to flow through it in order for your system to function properly. Modern cooling fan circuitry has advanced a great deal and is now as complex as any other side of the automotive electronic industry. Like your contactor, your capacitor needs to be wired correctly in order for it to function properly.

This will likely be back to your contactor. Gone are the days when the control method was a simple resistor. Now take the power wire from your fan and connect it to the wire that is going through the firewall. Battery recharging system Engine start system Headlamps Electronic ignition system Fuel Injection and Ignition System Scheme of a chain of sound signals Headlamp circuit diagram Radiator fan motor Heater circuit Circuit air conditioning circuit Stop lamps, direction indicators, alarms Tail Lights Starter circuit diagram Radio. Now cut the excess zip tie off for a clean look. One relay per fan is sufficient for systems with two small fans.
