Where does the radiator fan connect to?
Where does the radiator fan connect to?
A manual radiator fan is bolted to the water pump and runs off of the same belt as the water pump. An electric radiator has wires that connect it to the car’s electrical system.
Where does the wire from a cooling fan go?
The red wire from our relay connects directly to the cooling fan, and the black wire from the cooling fan connects to ground, both wires will utilize our supplied fan harness.
Do you need a relay kit for a cooling fan?
A relay kit, our part number CCFKRL, will include everything you need to properly wire up your electric cooling fans, with the exception of additional wiring needed to complete all of the circuits. The first part of the installation is to install the electric fan to your radiator, and remove the mechanical fan.
How big of a wire do I need for a fan?
RECOMMENDED WIRE SIZES: 8-10 GA: FAN POWER AND GROUND. 16-18 GA: ALL OTHERS. SIGNAL CIRCUIT 12V SWITCHED (IGNITION OR FUSE PANEL) Power “ON” when key is in the “RUN” position. 1ST RELAY TURNS ON FAN WHEN TEMP SENSOR IS ACTIVATED BATTERY 86 30 87 85 12V SWITCHED WIRE TO GREEN WIRE AT A/C CLUTCH.
What should the ground signal be on an electric fan?
The temperature sender, if used, is designed to provide a ground signal at about 185 degrees, and will shut back off when the temperature drops below 165 degrees. This wire (gray in our kit) supplies the ground signal to trigger the relay. The orange wire on the relay should see a 12 volt signal when the ignition switch is turned on.
How do you test a radiator fan relay?
Open your hood and take some time to locate your fusebox, which is mounted in front of the passenger side of the firewall. Remove the top cover to expose your fusebox and relays, check your radiator fan relays and remove them. Inspect for any damage to the pins or the body of the relay, such as bubbling or melting.
What is the function of a radiator fan relay?
The function of the cooling fan relay is to convert a low voltage signal from either the electronic control module (ECM) or a thermostatically controlled sensor. The cooling fan relay takes the low voltage signal and internally switches the relay “on” to allow battery voltage to be supplied to the radiator cooling fan.
Where is the radiator fan switch?
The radiator fan control switch is located on the transmission side of the engine near the EGR valve in same location as the coolant temp sensor for the Fuel Injection ECU.
Where is the radiator fan relay swich located?
The circuit controlling the fan contains a temperature-sensitive cooling fan switch and relay. The switch is threaded into the thermostat housing where it senses engine coolant temperature. The cooling fan relay is located in the left front corner of the engine compartment, just in front of the radiator coolant reservoir.
