Ideal Wiring Radiator Fan To Switch

After i put on my full aluminum half size radiator my car started getting hot while i was idling.

Wiring radiator fan to switch. Decided to wire up a switch to turn on fan when i wanted. Cut the power and ground cables from the fan motor. Attach one of the new wires to the positive wire and one to the negative cable and solder them together.

Can anyone. Take the second jumper wire and connect one end of the jumper wire to the positive wire from the fan. If you have any questions please comment.

Now find the red wire that is connected to the motor of the electric fan. Extend the other end of the jumper wire over to the positive terminal of the battery. You need to hard wire the radiator fan to a toggle switch on the dash in such a manner that the fan will shut off when the ignition key is off.

Link to fan switch below. Remove 1 2 of covering from the positive and negative wires running into the fan motor. If your mechanical fan had a fan spacer.

My old radiator fan switch only had two wires spliced into the two black purple wires going back ultimately to the fan motor. Post jul 23 2016 1 2016 07 23t09 20. 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. The fan can also be turned off manually when cruising to extend the life of the fan. However my replacement switch has three wires.
