AUTO COOL CONTOLS RADIATOR OUTFLOW TEMPERATURE - YOUR THERMOSTAT CONTROLS ENGINE TEMPERTURE~
THE HF CONTROLLERS WILL POWER BRUSH OR BRUSHLESS FANS. AVOID USING A LOW FREQUENCY CONTROLLER ON A BRUSHLESS FAN = IT WILL VIBRATE AT LOW RPM,
THE HF COTROLLERS HAVE SOFT START, AC FAN SPEED CONTROL, AND A COOL DOWN TIMER. RADIATOR OUTFLOW TEMP IS CONTRLLED WITH FAN RPM. ALL OUR SENSOR WILL WORK WITH ANY OF OUR CONTROLLERS, NO YOUR ECU! HF CONTROLLERS RUN AT 7000 CYCLES PER SECONDS.
Darryl,
I just wanted to let you know that the HF-125 I ordered from you this summer has been absolutely great. As I said, I haul a lot, and big trailers, with my Powerstroke, and now that I'm running your controller, I'm finally getting the benefits of converting it to electric fans. All these years hauling trailers and I've been religious watching temps - I still am, but I can tell you it doesn't matter now if it is 40*f or 100*f, loaded, unloaded, headwind, no wind, 50mph or 80mph, the temperatures are stable all the time. I could not be happier with your controller. In fact, I'm so happy I just ordered a second one for one of my other trucks that I'm converting to electric fans now that I have found the proper way to control them.
Thank you so much for making a quality product.

Full line of sensors for the Auto Cool Controllers
Copper Inline
Sensors:
If you have a PLASTIC radiator outflow port, you need use the inline copper sensor. If you use the standard brass sensor on the plastic port, it will not absorb the correct amount of heat. This will lead to a lower fan RPM that will let the radiator run hotter than normal.
The copper inline sensor can be ordered in 1.25 - 1.50 - 1.75 and 2 inch OD. Measure your hose ID for the best copper inline sensor fit. Be sure to email the diameter required.
One year warranty
on all sensors!

Standard Brass Sensor:
With each controller sold, we supply a standard brass sensor as standard.
However, if you order a Brass Plug or Copper
Inline Sensor, we do not include a Standard
Brass Sensor.
The Standard Brass sensor is mounted on the OUTFLOW port under the rubber hose. The sensor detects the outflow temperature and sets the fan RPM to keep the outflow port at a constant temperature.
If you have a radiator with plastic tanks and ports, you may want to order one of the copper inline sensor or the 3/8 inch brass plug sensor.
This sensor has a five foot twisted pair of 20 gauge wire that is connected to your Auto Cool Controller. If you add wire to the sensor line, be sure to solder the splice to avoid open failures down the road.
If you order one of the Brass Plug Sensors, please email us the size you need. 1/8 - 1/4 or 3/8 inch.
A short YouTube video on the Brass Plug sensors from the Auto Cool Guy. 1/8 - 1/4 - 3/8 NPT
Be sure to use TEFLON tape on this type of sensor
for proper seal and no leaks!
We can make you a special sensor to order. This one has an extra port for a drain.
Customer wanted to measure radiator inflow and outflow temperature with 1/2 inch ports on his radiator
The Standard Brass Sensor will form fit all out flow ports sizes! No need to tell us you want X size Standard Brass Sensor!!!!!!
We now have three Brass Plug Sensors.
1/8 inch - 1/4 inch and 3/8 inch
Be sure you tell the Auto Cool Guy the
size of the sensor you need for your
radiator. You can send an email or even a
phone call. All three have the same price.
Mount the Brass Plug Sensor close to the
outflow port if you can - on the bottom of the
radiator.
We supply extra twisted pair wire to extend
to your Auto Cool Controller.
BAD IDEA - LEADS TO
LEAKS IN RADIATOR
The guys at Brand X controller company has you stick probes into your radiator core. This can lead to leaks from vibration over time and miles.
Use only our sensor for Auto Cool, the brand X will not work!
THE STANDARD BRASS SENSOR
Here is a simple trick to raise or lower the temperature range of your controller. Running to COLD, install a resistor in SERIES with one lead of the sensor. Start with 1000 ohms to about 5000 ohms, or use a small pot to set it. Running to HOT, install a small resistor across the sensor terminals. Start with about 100,000 ohm and lower as needed. Use a small pot to adjust this and and replace with a fixed resistor. Call the Auto Cool Guy if you have any questions.
