How the Auto Cool controllers operate:
The sensor is measures the OUTFLOW temperature of your radiator
and then sets the fan RPM to regulate the OUTFLOW temperature you have dialed with the black knob. So if you have set the OUTFLOW temperature 10 to 20 degrees F. below your thermostat temperature you will have rock solid engine temperature. Use a laser temperature gun at the OUTFLOW to
check your regulation. Check it parked and motor at an idle.
Also keep in mind, that three things are going to effect the fan RPM.
First is your speed, second is motor loading, and outside air temperature.
Starting your engine for the first time you will NOT see the fans start.
I do not want to hear the BS term "KICKING ON." When the radiator has reached about 140 F, +/-, the fan or fans will start to turn slowly. The fan(s) will increase RPM and reach the point of regulation that you have set with the black knob. For A/C fan speed control, there is a small pot on the side of the controller that sets this fan speed. The radiator control will over ride this fan speed.
Brushless fans: If you have this type of fan, it will fibrate at low RPM unless your purchase our 7Khz HF-125 controller.
Our controllers have Soft Start that limits inrush current from starting a dc fan motor from a dead stop. This is what brand X controller boys fail to realize and why their controllers keep burning out. Auto Cool also has a cool down timer, so when you turn off the ignition, the fans will operate for under a minute.

ATTENTION:
YOU WILL NEED THE HF-125 FAN CONTROLLER @ 7,000 HZ IF YOU HAVE A BRUSHLESS FAN MOTOR.
If your run a brushless fan on a low frequency controller, the fan will vibrate out of control at low RPM.

DIESEL RADIATOR TEMPERATURE CONTROL
Hi good morning Darryl The Auto Cool Guy, from the Philippines Islands. Here is my HF-125 up and running smoothly on my 2000 LN166 Toyota Hilux 1kz-te diesel engine with rear mounted radiator beats that heat in the PI!
Best regards, nelbin binag

Sensor Warning: If your radiator OUTFLOW port is plastic, do not use the Standard Brass sensor. It will not get true heat transferred to the sensor! This will result in very low or no fan RPM.
US ARMY ORDINANCE:
CALLED UP FOR A TOUR IN SOUTH EAST ASIA AND ASSIGNED TO THE 295TH ORD. FROM HASTINGS & GRAND ISLAND, NEBRASKA
10-68 TO 10-69.
The photo on the left is the Auto Cool Guy. Location was north of Quan Tri City just south of the DMZ. When we were out of our base camp we always carried our M16s and at least 8 clips of .223 ammo with 20 rounds in each clip.
The photo on the right was taken one night outside of our hooch in Da Nang. For some reason I loaded 35mm high speed slide film in my camera and had it mounted on a tripod ready to go that night. As we were drinking beer and such, all hell brook loose and the sirens went off. Then we heard one of our NCOs telling us to get into our bunker. We answered back to this NCO that we were busy drinking and taking war photos. With my camera and standard lens I shot this time laps photo of a Cobra gun shop spraying 7.62mm rounds on the Da Nang perimeter. In the morning all the MPs found was a dead water buffalo. So you see all the fun you can have in the Army!
We have been building pulse width modulated radiator temperature controllers right here in the USA starting in 2011. We design and build quality and what the customers want!
The Auto Cool Guy supplies the Standard Brass Sensor with your controller. However, if you purchase a Brass Plug Sensor or one of the Copper Inline Sensors, we do not supply the Standard Brass Sensor as the default sensor with your order.
Attention Australian buyers: The cost to ship controllers to your country has gone way up! Fed-X will be the system used from now on. We will get a shipping cost and email you the added expense. There may also be a delay in Pay Pal payments to us. What a bloody mess!
