Does anyone here use the Dakota Digital PAC 2750 or the Painless 30140 Fan Controllers? If so, I would like to here your opinions on reliability and functionality. Any problems at all?
I have a disconnect on my battery that I regularly use.Thanks for the comments everyone!
Jim and Roger,
Have you ever disconnected the battery since you've installed the controller? Did you have to reset/reprogram the controller all over again?
Great news, Roger.. And it kicks both fans on high when the a/c is engaged, correct? Not just one fan?I have a disconnect on my battery that I regularly use.
The controller has never lost it's settings.
What's the point of that? You're not cooling the engine, just the radiator.I just recently had a switch installed so sometimes when I shut the car off I turn on the fan so it can run a long as I feel needed.
Good to know, Rick.. thanks. However I will be mounting the controller inside. If I was running a modern engine I would use the PCM as well.One of those units mentioned had water ingress problems, though they may have been fixed by now. I forget which one.
That is something I'd want to know about.
Myself, I'm using the PCM for the EFI for fan control. Dual fans, half speed/full speed.
You and I discussed this quite some time ago. Some manufacturers do it. I'm sure you've seen the warning messages under the hood. With the Dakota, the fans wont start unexpectedly. They will only continue to run (for the time choice that you program in) if they were running at the time you shut the engine off. Probably not a real safety factor especially if you set the time short.What's the point of that? You're not cooling the engine, just the radiator. It would be different if you could circulate the coolant too, but that would require an electric water pump drive.
When you first turn any car off the heat spikes as the water is not flowing. The twin fans blow so much heat off radiator and engine you would be surprised. Like when a motorcycle moves through air it really transfers off the heat, stop and cooling goes way down except for the oil doing it's job. IMHOWhat's the point of that?
