Expert Answers about Radiator Fans
- How Does Push-In Probe Install on Derale Fan-Control Thermostat
- Yes, the Derale Replacement Push-In Probe for Adjustable Fan-Control Thermostat # D16760 does get inserted into the radiator core between the fins.
This is a replacement probe for either the Derale Adjustable Fan-Control Thermostat with Push-In Radiator Probe # D16759 or the Derale Single-Fan Adjustable Fan-Control Thermostat with Thread-In Radiator Probe # D16779. Both of which can be set to turn on when the temperature reads anywhere between 150 to 240 degrees and will shut off once...

- A dual-fan 4,000 CFM set-up would move more air over a larger portion of the radiator than a single 3,600 CFM fan would. The dual-fan set-up would be my recommendation.

- Diodes like the # RM-790 are just to prevent feedback by allowing electricity to only flow one way and wouldn't provide the same function as a transfer switch to go between the two power sources, if that's what your goal is. You would need a automotive grade relay with two trigger wires to separate the two power sources so that the fan can be triggered by the ECU at the set temperature and with your switch.

- A transmission cooler has plenty of gaps between the coils and fins that will allow air to easily pass through it. The transmission cooler will not interfere with the cooling process in any way.
I have linked you to some FAQ articles that you might find helpful.

- The Flex-a-lite Direct Fit LoBoy Electric Radiator Fan - 2,500 CFM # FLX328 is a puller fan without controls. If you want thermostat controls you will use # FLX318 which is the same puller fan but with the addition of the controls.

- The Derale 4 inch diameter High-Output Fan # D16104 is designed for a 12-volt electrical system. If you could find the appropriately-sized battery that would fit on your bike, it should work. You'd have to pull the battery off the bike to charge it frequently, however.
The fan is a puller-application designed to pull air through a radiator, so it would need to install inboard of the radiator.

- The Derale Adjustable Fan Control Thermostat you referenced, part # D16789 will not shut off at a certain vehicle speed, but at an adjustable fluid temperature.
The temperature at which the fan turns on is adjustable between 150-240 degrees Fahrenheit. The fan automatically shuts off once the fluid cools by 10 degrees. So, say you set the thermostat to turn the fan on once the coolant reaches 190 degrees. At 190, it would turn on and run until the coolant reached 180 degrees.

- The key temperatures to monitor when towing are the transmission fluid, engine oil and coolant temperatures. Each of these fluids will have different ranges that you will want to stay within.
For transmission fluid, the ideal operating temperature is between 160 and 200 degrees. If you find that you are running over 200 degrees, I would recommend installing a supplemental transmission cooler, like part # D13504, if you do not already have one. I also recommend using the Ford radiator...
