Electric fan 04 Yukon

[rlvaldez]

I want to upgrade to an electric fan and have read that people have used the Dorman 620-654, i would like to know if i can use this is my 2004 Yukon and what harness/wiring i would need and where i can get them. Thanks.

Yes, those will work. You can get the harness here: http://www.ls1fans.com/2003__Truck_SUV.php

You will also need to have your PCM (engine computer) programmed to turn the electric fan function on. You can get that through Blackbear Tuning. They are on this site.

That's the fan and harness I have sitting in a box waiting for me to put them on.

what ever you do make sure all the connections on the relays are tight or otherwise youll be melting the relay harnesses and relays left and right. I had to actually take the wires out the relay harnesses and plug them directly to the relays
