I bought the flex-a-lite 292 for my 03 Silverado with 28" wide radiator. The wiring directions are a little weird. Also I am trying to get the old fan off with the single big nut and having problems. After I do get it off and remove the fan, what should I do, go buy a big nut or put the fan clutch back on the end of the water pump without the fan? The directions kind of suck, needs more pics. I also don't like having to cut into the A/C wiring and somehow need to figure out which wire is the trigger wire and whether it is + or - . Probably call them tomorrow...

I think I found the answer to my question in Tbyrne's post about his install.

 

If anyone else is thinking about using these here are a few quick notes that will help your install.

 

The fan controller needs to be connected to a wire that is hot when the truck is keyed on and cold when it is off.

 

If you take the cover off of the fuse box under the hood and then lift up the cover that has the fuses in it you see 6 different sections. I used a wire in section 1 ( top left hand corner). Count two wires over from the right and 3 down.

You will find 2 wires here. I used the purple one on the right.

 

You also need to tap into the activation wire that goes to the clutch compressor for the AC.

 

There are two wires there. I used the green one. (I guess that's the positive wire.)

 

These tips should help you get through the install in a couple of hours.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
