5523Pathfinder Posted September 6, 2009 Share Posted September 6, 2009 (edited) Anyone who has hooked up a electric fan controller on your rig....... Where did you get the switched power source from??? Everything else is hooked up, just need that info. Location, wire, connector, any extra info would be appreciated!

beastpath Posted September 6, 2009 Share Posted September 6, 2009 i ran a wire through the firewall on the drivers side and hooked into one of the wires coming out of the fuse box. dont remember which one. make sure it is one that only powers on when you turn the truck on, like fuel pump or something.

5523Pathfinder Posted September 6, 2009 Author Share Posted September 6, 2009 Well, I only have about a 1 1/2 foot lead. I dont really want to run it all the way inside. I did find a switched source on top of the engine hand my harness reaches. Im going to try ther ena see what happens. Im sitll looking for other options if this doesnt work.

Toby Posted September 6, 2009 Share Posted September 6, 2009 I'd suggest the fuse box personally. But if you're going from an underhood source it'd be a little more difficult. No matter what just make sure you fuse it lol. Can never be too careful. Link to comment Share on other sites More sharing options...
beastpath Posted September 6, 2009 Share Posted September 6, 2009 yeah, shouldve said that I added a manual switch in the cab too. any switched source should work though. Link to comment Share on other sites More sharing options...
5523Pathfinder Posted September 6, 2009 Author Share Posted September 6, 2009 Well, it finally got hot enough and ran. I dont have my temp probe here with me at the moment, so I dont know exactly what temp its coming on at. But it is working. Link to comment Share on other sites More sharing options...

Wasn't the pathfinder already equipped with an E-Fan? Or did you just install a more efficient fan? Link to comment Share on other sites More sharing options...
5523Pathfinder Posted September 6, 2009 Author Share Posted September 6, 2009 it had a fan, but the controller went out. The old controller isnt availble anymore and the new one was different. I have a laser thermometer at work Im going to bring home and see what temp it comes on. What temp do others have thier set at? I know the newer cars with e-fans dont come on until over 200 degrees. right now it comes on with the needle about half way. Link to comment Share on other sites More sharing options...
Precise1 Posted September 7, 2009 Share Posted September 7, 2009 Isn't 190ish the good running temp for these motors?? I remember someone (of knowledge) posting this in a thermostat thread... What does that equate to for the e-fan setting, I'm not sure... B Link to comment Share on other sites More sharing options...
beastpath Posted September 7, 2009 Share Posted September 7, 2009 180 is supposed to be optimal for the our trucks. the fan should come on when the thermostat opens, so if you put in a 170* thermo set it at 170, if its a 180* thermo set it at 180.

5523Pathfinder Posted September 7, 2009 Author Share Posted September 7, 2009 Well, I went for a test drive and the temp needle never went above half way. Like I said, I will bring the laser thermometer home on Tuesday night and maybe tinker a bit. All is well though. Link to comment Share on other sites More sharing options...
jj big shoe Posted September 9, 2009 Share Posted September 9, 2009 Is it an adjustable controller? Just pop the radiator cap off (when cold, of course), start the engine and wait for the coolant to start flowing, then dial in the controller.

87pathy Posted September 9, 2009 Share Posted September 9, 2009 i ran a wire through the firewall on the drivers side and hooked into one of the wires coming out of the fuse box. dont remember which one. make sure it is one that only powers on when you turn the truck on, like fuel pump or something. you should hook it to a thermostat and constant power. so that when you shut the engine off, it continues to cool. but automatically shuts down with either a switch, or thermostat Link to comment Share on other sites More sharing options...
ca91pathy Posted September 10, 2009 Share Posted September 10, 2009 I pulled power for mine off the coil. It is only a trigger and the amperage comes from the battery Link to comment Share on other sites More sharing options...
beastpath Posted September 10, 2009 Share Posted September 10, 2009 you should hook it to a thermostat and constant power. so that when you shut the engine off, it continues to cool. but automatically shuts down with either a switch, or thermostat thats the way it is hooked up now, but I don't agree with having it run when you shut the engine off. Why do that? The fluid is not circulating through the engine as the waterpump is not running, so essentially you are just cooling the fluid in the radiator and wasting some power from the battery. I mean, the mechanical fan doesnt keep running after the engine is shut off. just my 2cents Link to comment Share on other sites More sharing options...

frecklecolouredbrain Posted September 11, 2009 Share Posted September 11, 2009 i did this a while ago and had an issue with the switch not getting hot enough. engine temp would be at max before the 180C switch kicked on. measured the coolant and it turns out that when my coolant is at 200 my rad is 175-180. but I never got the controllable switch. On the plus side, it doesn't matter what speed i'm at, just the rad is enough to keep the needle centred; It only starts to overheat if I idle for a while, so i figure i'm just gonna wire the switch to my brake lights and put a manual over-ride in there somewhere. That way, if i forget about the switch, it'll come on while i'm at a red light. Everybody, put your hand up if you hate electrical too!! Link to comment Share on other sites More sharing options...
jj big shoe Posted September 11, 2009 Share Posted September 11, 2009 Do you have the temp probe in between the radiator fins snug? I have an adjustable t'stat and put the probe inside the upper radiator hose. If the probe wire is thin enough, take the hose clamp off at the radiator and slip it in there. You might get a bit of a leak, but simply wrap the radiator neck with some electrical tape before you put the probe in and the hose back on. The tape should make a softer seat so the probe wire sinks in and will seal any gap between the radiator inlet and the hose once you clamp it down.

5523Pathfinder Posted September 11, 2009 Author Share Posted September 11, 2009 I was able to use the previous temp probe position. So far so good. I will be checking the temp this weekend. Link to comment Share on other sites More sharing options...
