hello peeps,im wondering if anybody has any ideas why the fans wont come on in mysaff 4by4,have just got a new fan switch for it and tried that still to no avail,so next was told it could b the thermostat so then changed that.still nothing and im stuck for wot else it could b as it used to cut in quite low on temp gauge b4,it also works if you run it live on constant so dont i suspect the wiring to b at fault as so i know the fans work ok.i dont know wot to check next and im running out of ideas and dont want to end up cookin the damn thing so any sugges, would b agreat help.ps wot do you reckon the chances of the new fan switch being faulty too.(gen ford 1) as im at my wits end thanks again rick e.

 

check the fuse box as they burn inderneath you will have to do a rewire job its a common fault and has cliamed a few engines and head gaskets so get it done soon

 

IF you bridge the fan switch it works yes? or have you got a fan bypass switch somewhere. Unplug the fan switch an dbridge the plug with a paper clip. If it works the fault must lie with the switch. If not the plug is probably fubar

 

Join the 2 wires together that go to the temp switch in the rad and see if they kick in! If they do your new switch is fooked if they don't then you have a wiring fault elsewhere.

 

So true

 

Common fault on Cossies. Mainly the 2wd ones.

Fuse melts and you end up with needing a rewire.

Check the fuse and bridge out the fan switch plug and see what happens.

 

Had this on my old 2wd mate. If I started the car from cold and left it to tick over on the drive the fans would kick in when the engine reached the req temp. However if I was to drive the car and get everything hot and load the electrical circuits as normal the fans would not operate. After numerous hours I eventually traced the fault to a dodgy engine earth lead. Hope this helps mate.
