Electric Cooling Fan Temperature Probe How To

2011 May 13
by admin

 

Flex-a-lite's most popular fan controllers are adjustable between 160 and 240 degrees. These controllers are operated by a probe that can either be put in the core of the radiator fins or the radiator inlet. Putting the probe into the radiator fins is accurate, does not require any special tools and, when done correctly, will not damage your radiator core. You've probably been taught that radiator cores are delicate and you shouldn't touch them. The truth is that, while you do need to be careful, it's easier than you might think to push one of our temperature-sensing probes into the radiator without causing any problems at all.

Tips for a successful fan controller installation:

  • Position the probe close to the coolant inlet (top of radiator)
  • Insert the probe until there is about an inch remaining outside of the core
  • Don't insert and remove the probe in the same position several times
  • Route the temperature probe and all wires before mounting the controller to make sure everything will reach
  • Always run the positive and negative leads from the controller directly to the battery

As always, you can call our tech line at 253-922-2700 if you have more questions.

    Okay, I have to admit that I've never liked the idea of pushing something through my $500 aluminum radiator. But I've installed two of these and it's no big deal. They work great!

    is it allowed to mount the variable speed controller in the engine bay of a Streerod? small room, hot air, maybe wet as well? i bought one and have to know this to be sure, thanks, Marcel

    What if the fins are too close to allow the probe to be inserted? Can it be mounted elsewhere (zip tied or epoxied to the tank or fins)?

      It is designed to be inserted into the radiator fins. If you can't use it in your radiator, we have a fan controller with a thread-in temperature probe. Give us a call at 253-922-2700.
