Was wondering if there was a simple way to make my e-fans cool down the coolant and engine to a specific temp after shutting off the ignition and walking away?

toggle switch is the only way i know of. get a two prong toggle switch, run one wire to power source and the other to tap in to pin 42 to ground out the pcm.

 

Yep I've been thinkin of doing this also but I don't want the toggle inside the truck so I guess I will put it under the hood.

 

There is a setting in Hptunners. Ignition off "disable temp" and "run time". I have mine set to run for a minute after the I shut the truck off.

But to make it really affective you really need an electric water pump.

 

I'm glad someone knew what I was asking. My Black Magic e-fans that I added to my old 93' GT had that capability, to bring the radiator down to a certain temp I set it to, then shut off.
I guess there is no way to do it that way on my truck.
I would like to have them run for a 60-90 seconds after truck is shut off like yours does.
Does it do it everytime the ignition is shut off, or when the PCM detects a normal operating temp? I would rather it not cycle everytime it is keyed on then keyed off.
Any insight on this?

Doesnt the Dakota Digital controller have that feature built in??

 

I would have no idea what-so-ever.
That's why I'm asking how to make it do what I want it to do.......
Anyone else?

Have nelson change your fan settings as joshluther said... It will only run if the coolent is over the "disable temp" and will only run for the time selected in the "run time" tab. I think that is as close as your going to get unless you add some type of controler.......

 

I got ya, thanks!

most definitely!! All you need to do is program it if you have the nelson harness!!! If you don't have one then you need to use relays to do it
