Read the return policy! I installed this product and it didn't work.I spent about 2 hours troubleshooting trying to figure out what the problem was and it's a bad unit. Come to find out they don't take any items back that have been installed.

Products is a great value for the money. The people at etrailer kept me informed of my order status by email and phone. Short backorder delay but nothing to long.

The Fan control was delivered as I was told it would be, I have not had a chance to Install it yet. But I feel very sure if there were any problems to arise this company would do exactly as they say they will.
I will recommend e.trailer to anybody, And for sure use them again myself.

Works like a champ! I had some problems initially with the unit not working correctly. A call to customer support helped identify a faulty control. A new part was shipped and it works as advertised. I was able to fine tune my cooling system and my vintage Mustang is working great.

- Adjustable Fan Control Recommendation for Engine Cooling FanThe best thing I can recommend for you would be the Derale Adjustable Fan Control Thermostat # D16749. This product is adjustable from 150-240 degrees so it should work very well for you once set where you wanted it. At this time we do not offer any thread-in fan control switches like the # D16731 that you referenced that are 195 or 200 degrees.
view full answer... - What Fan Controllers Does Derale Probe D16750 FitThe probe part # D16750 is a replacement for the part # D16749 and the # D16778 but not the PWM style of controller part # D16795 that you referenced.
view full answer... - Thermostat and Probe for a High-Output, Electric Radiator Fan-and-Shroud Assembly, # D16934Because the High-Output, Electric Radiator Fan-and-Shroud Assembly, # D16934, contains two fans that operate independent of one another, you will need two Adjustable Fan-Control Thermostats with Thread-In Probes, # D16749. The wiring that comes with the thermostat is required and each fan will need a complete D16749 to make them operable. The only extra wiring that might be needed is if the mounting locations for the thermostat and/or probe are too far away. In that case, extra wiring...
view full answer... - 17 inch Fan Recommendation for Use with the Derale Adjustable Fan-Control Thermostat D16749Sounds like you factory fan draws too much amperage to function properly with the # D16749. The # D16749 has a maximum capacity of 25 amps, so as long as you get a replacement fan that draws less than that you would be fine. For a fan that draws less than that and can flow up to 2,400 CFM you would want the # D18217. The high speed power draw is 23.5 amps and the low speed draw is 17.4 amps.
view full answer... - Where does the Brass Probe Connect for the Derale Adjustable Fan-Control ThermostatThe two black wires coming from the brass probe end in a white plastic connector. That connector will plug into a mating connector on the main wire harness. I had these parts in stock, so I made a short video for you.

- How To Determine Fit Of the Derale Adjustable Fan-Control Thermostat On an ATVThe Derale Adjustable Fan-Control Thermostat with Thread-In Probe part # D16749 as you pointed out is a universal fan controller. Therefore I cannot confirm fit on specific applications. That said, what you can do to ensure fit is verify that you have a 12 volt electrical system and have a way to attach the radiator probe which uses a 3/8" NPT fitting. If so, you will be good to go.
view full answer... - Is the Derale Adjustable Fan-Control Thermostat # D16749 UniversalI pulled a Derale Adjustable Fan-Control Thermostat, part # D16749, from our warehouse to see how it installs and found that this product is universal. The plugs that you see plug into the included relays and included thread-in thermostat probe. This product connects to the fan with cut wires that will be connected with the included butt end connectors and does not require that you have a certain connector from the fan to install correctly.
