bupalooga Silver Donating Members 262 Member For: 12y 7m 6d Gender: Male Location: Griffith NSW Posted 04/11/15 07:44 AM Share Posted 04/11/15 07:44 AM My Thermo fans seem to be very trigger happy, this was a big pain last summer so Id better deal with it sooner. I could come home at even 3am, pull up in the car port and the thermo fans could run for like 3min after the car is turned off, no matter how easy I drove it & with the aircon off.They come of occasionally in Winter but basically all the time in Summer. Iv even had them start running as soon as I put the key in the ignition when it was last driven over an hour previously.Note that I do live in a very hot & dry area but the fans really don't need to be running like this with the car off.Temp gauge is usually a little below half.Is there a sensor or something I could try replacing?

The temp fluctuates a bit and the thermos come on when they need to, temp drops again and a cycle occurs. If you pull up and switch off just as the fans have been called to run its probably a good thing that ford made them run regardless until a cut out temp is reached.Probably could be altered in a tune but maybe not a good idea? Your car usually gets hotter when you switch off initially.

Should keep it cooler and stop them running after shutdown.

Now tuned they are quite often on when the cars running but they turn off always when I turn it off.

Without coolant circulating they wouldn't do much for the engine anyway?Sent from my 0PJA10 using Tapatalk Link to comment https://www.fordxr6turbo.com/forum/topic/91337-can-i-stop-thermo-fans-from-running-while-the-car-is-off/#findComment-1568309 Share on other sites More sharing options...

k31th less WHY; more WOT Site Developer 29,492 Member For: 17y 1m 2d Gender: Male Location: Melbourne Posted 05/11/15 10:36 AM Share Posted 05/11/15 10:36 AM Change thermostat and tune to have it come on earlier, like suggested earlier. This will keep it cooler and will only run for a few seconds at most on shutdown. Factory settings for the fans seems to bring 'em on a little too late.

I asked Pitlane to replace my thermistat with a new one and its been okay since. Does come on when needed but its not on all the time like it used to. I suspect mine had gone faulty.

spook Donating Members 180 Member For: 17y 1m 7d Gender: Male Posted 05/11/15 12:34 PM Share Posted 05/11/15 12:34 PM Not sure why but my fans turn on (low speed) as soon as I turn ignition on - no matter what temp.If temp creeps up to half way then high speed kicks in. Otherwise low speed all the time till I kill ignition.
