2005 Silverado 1500 5 3 Low Speed Cooling Fan Wiring Diagramо Cooling system diagram for 2005 chevy silverado. the cooling system in a 2005 chevy silverado is an essential component that helps regulate the temperature of the engine and prevent overheating. understanding how the cooling system works can help you troubleshoot and maintain your vehicle. radiator: the radiator is the heart of the cooling system. Fan control relay. pin 30 to negative side of low speed fan. pin 85 ign power. pin 86 ecm x1 harness pin 17. pin 87 to ground. pin 87a to positive side of high speed fan. with the requested information above i'll be able to wire up the fans to the factory location and put together a write up on how to do the install.
2005 Silverado Cooling Fan Wiring Diagram If so, then the 2 wires that go to pcm have a disconnect, you can remove the end and then probe each wire on the relay side of the harness with a simple ground and it should make the fans turn on. my build log: silentbravo's 2001 gmc sierra 2500hd. 2003 gmc sierra rclb. my channel. 3. after the vehicle is shut off if the engine coolant temperature at key off is greater than 101°c (214°f) the low speed fans will run for a minimum of 60 seconds after 60 seconds, if the coolant temperature drops below 101°c (214°f) the fans will shut off. the fans will automatically shut off after 3 min. regardless of coolant temperature. Relay trigger wire (in addition to the low speed green trigger wire). when all three relays are energized a. ground path is provided for the left cooling fan, as well as battery positive voltage to the right cooling fan – thus. during high speed operation both engine cooling fans have their own ground path, resulting in a parallel 12 volt. List of elements for 4.3l vin x, a t wiring diagram for chevrolet silverado 2005 1500: engine coolant temperature sensor (rear of left cylinder head) intake air temper ature mass air flow sensor. splice pack sp205 (in dash harness) 4.8l vin v, a t wiring diagram, except hybrid for chevrolet silverado 2005 1500.

Start with taking both of the positive wires from the fans and connect them to the yellow wires on each relay. you will then need to run switched power (usually from your ignition switch, but modern replacement wiring harnesses usually have a fused fan relay trigger wire) to the blue wires on the relays. next, both of the black wires from the. Shreveport. this is a step by step tutorial on how to upgrade any 99 02 gmt800 truck or suv to the 05 06 gmt800 electric cooling fans. this same setup can be used on 03 04 trucks as well, however the only difference is the wiring that connects to the pcm. i will also add that a custom tune from someone like blackbear performance (who is a site.
